Were The Americas Settled Twice?
A team of paleoanthropologists report in PLoS One analyzed the skulls of several dozen 11,000 year old Paleoamericans and compared them to the skulls of more than 300 1,000 year old Amerindians. They concluded that based on the morphology, there were two distinct waves of colonizers from Asia.
While we know from a couple genetic studies there are at least two, if not 3 or more waves of colonizers, the morphological evidence is now beginning to make a lot more sense along with the genetic evidence. There’s some concern why the authors didn’t have more North American and Asian samples for comparison, but that’s almost always a critique in any anatomical study.
Two comments in the Science Now news article are particularly entertaining regarding this topic:
“Very interesting–don’t tell some of the tribes in california–they won’t be able to handle real information like this.”
“Exactly. It sounds like the Amerindians stole the land from the Paleoindians? I guess they should pay restitution, right?”

Inuk’s Ancestry: The 4,000 Year-Old Paleo-Eskimo Genome
Hi all, this is Kambiz. I’m resurfacing to share with you a new Peopling of the America’s research that peeked my interests. The Nature paper is titled, “Ancient human genome sequence of an extinct Palaeo-Eskimo.” The preserved nuclear DNA of a 4,000-year-old man’s tuft of hair, found out of Greenland’s permafrost, has been sequenced and many new pieces about his phenotype and ancestry are published in the current paper..
Aside from his brown eyes, brown skin and facial hair, there are similarities (that I don’t know of because I haven’t read the full paper) which most closely resemble those found in indigenous inhabitants of eastern Siberia… Possibly the Saqqaq. The findings support the implications of the team’s mitochondrial DNA analysis of the hair previously published in Science in 2008. We’ve covered that paper before, here and here. The previous study also showed patterns of Siberian origin, and a distinct break between the Dorset culture and the ancestors of modern Inuit people.

Discrepancy Between Cranial & mtDNA Data Of Early Americans Or Sample Size?
There’s an interesting discussion brewing about on Dienekes’ Anthropology Blog about the ancestral discord between the genetics and craniometric traits of native American populations. I wanted to point it out to all in case you don’t subscribe to Dienekes. The discussion revolves around a rather new PLoS One paper addressing the observation that while native American mtDNA remained relatively static since the Holocene, the cranial morphology of the group has undergone major shifts. The paper is open access and can be found at this link, “Discrepancy between Cranial and DNA Data of Early Americans: Implications for American Peopling.”
Dienekes addresses 3 hypotheses as to why this could be. I generally subscribe to the third hypothesis he mentioned. But in focusing on the paper I have found some concerns about the study sample. Firstly the samples originate only from Argentina. I’m not surprised about this as the researchers are Argentinian scientists, however how can one draw ‘implications for American peopling’ when the sample is confined to 16 individuals from Patagonia and the Pampas? What happened to checking out specimens from Brazil, central America, and the northern territories?
Furthermore, the samples come from a 1,500 year time frame… starting at 7,800 years ago. We know the earliest migrations to the Americas started 40,000 years ago and people didn’t just make a B-line to Argentina. Populations dispersed. So to make conclusions about Paleoamerican and Amerindian groups based off of 16 skulls from a narrow spatial and temporal window in the peopling of the Americas is flawed, even if these 16 skulls seem to be consistent with morphological and genetic variation patterns interpreted as differences between Paleoamerican and Amerindian groups.
I don’t want this to turn into a time old critique on sample size and distribution analysis. I think we all know that bioarchaeological and paleontological studies also have many reasons to narrow samples. Sometimes it is political, while other times it is based plainly on accessibility to samples as to why a study is narrow. But that doesn’t give anyone an excuse to go ahead and publish it!

More Older, Maybe Even The Earliest, Dates For The Occupation Of South America
Dienekes briefly introduced a new paper which attempted to reassess the age of the earliest human settlements in southern Chile and Argentina through radiocarbon dating. This is an important anthropological paper since the dates on peopling of Americas are being pushed back further and further. You may remember the seaweed analysis from Monte Verde, Chile from May, which confirmed the older, contested radiocarbon dates of the site.
This new paper, “AMS 14C dating of early human occupation of southern South America,” is similar in that the authors reanalyze carbon bearing material (charcoal or animal remains) from the Arroyo Seco 2, Paso Otero 5, Piedra Museo, and Cueva Tres Tetas sites in Argentina and the Cueva de Lago Sofia 1 and Tres Arroyos sites in Chile.
For all but one of the sites, the re-dating yielded consistent results to the previously published dates. But Arroyo Seco 2 had older dates, calibrated to as old as 14,000 years ago. And in fact show three different occupation periods, one around 14,170 to 13,840 years ago, another around 13,710 to 13-350 years ago, and a final one around 13,210 to 12,950 years ago. If you had any doubt on whether or not the material indicate human occuptation, the bones from Arroyo Seco 2 clearly show signs of human modification and were found associated with a lithic assemblage. An example of megafauna taphonomy from Arroyo Seco 2 can be found at this link. Also there, you’ll see some of the stone tools and artifacts recovered.
The authors challenge the Monte Verde site, stating their analysis has pinpointed the earliest known occupation in South America, but the difference is only in 50 radiocarbon years. Somewhat negligible given that level of atmospheric 14C haven’t been strictly constant…. even over 50 years they can vary. Regardless, this study reconfirms what many recent studies have been telling us, that there were pre-Clovis cultures in the Americas existing for several thousand years.
Just who those people were and how they got there is still rather unresolved. Craniofacial analysis of human burials from the site dating to 8,500 years ago (I know, no where close to 14,000 years ago) indicates that those Arroyo Seco 2 people differ considerably from the more or less contemporaneous Lagoa Santa people. But, mitochondrial analysis suggests that extant populations are related to those that made the migrations over Beringia. It is certainly possible that other people traveled by boat and did not contribute a significant impact to the current genetic makeup of south American populations. Either way, the Americas was peopled much earlier than what I was personally taught, and that is exciting.

Peopling Of The Americas: Eva de Naharon, A 13,600 Year Old Skeleton Found Near Tulum, Mexico
National Geographic News is running some press about the oldest skeleton found in the Americas, Eva de Naharon, at 13,600 years old. This would make her the oldest known human in the Americas, but as of now no peer reviewed journal has reviewed the research. The discovery of the skeleton, along with three others, were actually announced in a bulletin dated back to June on Mexico’s National Institute of Anthropology & History website.
The site is located in the Mexican state of Quintana Roo, which is on the Yucantan Peninsula. I’d map the actually cave but I can’t seem to track down a locality name nor any GPS information. Alls I know is that its somewhere near town of Tulum.
The lead investigator of the study is Arturo González, who says these particular remains have 10 teeth. Surprisingly, the skull morphology does not exhibit many affinities to northern Asian populations, you know like Siberians and the like. This conclusion comes from Alejandro Terrazas, of UNAM. Rather, the skull exhibits South Asian, almost Indian, like traits. No discussion nor description of what the actual traits are provided.
The remains have been dated via radiocarbon. But the remains have since been flooded over as the ice caps melted after the last glacial maximum. David Anderson says the saltwater that’s covered the remains affects carbon-14 dating. But the presence of elephants and giant sloths in the cave give some bio-chronological support to the date.
So is this surprising? Yeah, but there have been signs pointing to a much older occupation of humans in the Americas. Recently, a genetic study suggested that the peopling of the Americas started around 17,000 years ago and a redating of Mexico’s Toloquilla footprints indicated that people may have been in or around central Mexico by 16,000 years ago. Furthermore, sites inside Chile have been redated to be as old as 14,200 years. But, should the radiocarbon dates hold, this will be the oldest American skeleton. You may know of Kennewick’s 9,300 years old date, but with Eva de Naharon antiqutity at 13,600 years, this maybe a significant find.
The peopling of the Americas is one of my favorite subtopics in anthropology and Eva could shake things up especially if the carbon-14 wasn’t affected by saltwater and her physical traits are really south Asian-like. I guess we gotta wait until González and team excavate, clean up, and analyze Chan hol, the fourth skeleton at this site and submit their analyses to a journal.
On Mexican Toloquilla Footprints and the “Peopling of the Americas”
This post is intended as a follow-up to Kambiz’s review of the new dates for Toloquilla footprints. Frankly, it’s been very tiring to read and watch all the current and past powwows about the validity and veracity of pre-Clovis sites. Science is currently making a huge methodological mistake by assuming that the early presence of humans in the Americas has to be “proved.” In fact, we need to do the opposite:
- let’s assume that all continents (America, Africa, Europe, Asia/Australasia) had modern humans (anatomically AND behaviorally) for at least 40-50,000 years ago;
- then let’s try to demonstrate, using geography, archaeology, paleobiology, odontology, craniology, genetics, kinship systems, ethnology and linguistics and simulating different population scenarios, that all but one of these continents were in fact peopled from an adjacent continent earlier than the set date;
- whichever continent turns out to be most resistant to this kind of multidisciplinary experiment will be the one from which humans originally radiated to all other places.
Right now, hypothesis 1 cannot be rejected for any of the continents, including America. And it’s not the matter of whether Tom Dillehay mixed up the strata in Monte Verde or Toloquilla footprints may not be 40,000 years old. Clovis-I proponents (as well as the new wave of 16,000-YBP-proponents) should understand that “pre-Clovis” is first of all not found in Siberia/East Asia, and that they need pre-Clovis sites in America in order to make “the peopling of the Americas” empirically demonstrable (Dziebel, G. V. 2000. The Test of a Null Hypothesis for the Origin of American Indians //Current Research in the Pleistocene 17: 125-127. Corvallis, OR: Center for the Study of the First Americans). Once convincing lithic and paleobiologial evidence is presented to show that humans indeed peopled the Americas, then we can move on. As of now, scholars are methodologically confused, hence all the irrational fights around pre-Clovis sites.
It’s true that archaeological finds earlier than 12,000 YBP have been slow in coming in the Americas. Notably, some of the most interesting ones indicate human presence vicariously: scat in Oregon, footprints in Mexico, skin flakes in Pendejo Cave. There are several reasons for this paucity:
- Looking for the traces of human activity, we apply the standards of the European Paleolithic, thus assuming ad hoc that these standards are universal and will turn up legitimate finds in Africa, Australia, Asia and America. But what if pre-Clovis in the Americas was an adaptation based mostly on soft, perishable technologies? What if humans didn’t utilize stone tools that much? According to Alan Bryant, only 20% of tools collected from a modern tribe are lithic; the rest is bone, fiber, wood. These tools will never be highly visible in the archaeological record;
- Population size and density were very low;
- Methodological confusion referred to above regarding what has to be proved and what has to be assumed;
- Ongoing biases against America as an old continent and the legacy of the conquest. In Transcaucasia, for example, the Azeris and the Armenians have been having land disputes for centuries; not surprisingly, the scholars on both sides have been trying to justify their respective governments’ current land claims by portraying the other party as a “recent” immigrant into the disputed area. By the same token, the colonization of the Americas naturally led to the suppressed estimates of the native populations’ age. And let’s not forget that we’d decided that America was a “new” world long before scientific method has prevailed in the descriptions of nature and culture. America as the New World, i.e. the world not mentioned in the Bible, is a relic of our pre-scientific worldview, and its short Clovis-I chronology is a local survival of the original world short chronology presented in the Bible. As of now, after decades of search, there’s no scientific evidence that indicates that America is a recently populated continent. Only a perverted logic would require a small group of “dissidents” to prove that America is old.
The new dates for the Toloquilla footprints at 40,000 YBP are fully consistent with the fact that Siberia hasn’t furnished the necessary evidence to demonstrate the origin of the earliest American lithic assemblages outside of the Americas. It means that the roots of Clovis, Nenana and other incipient early American archaeological cultures are in America, all the way back to 40-50,000 YBP, unless convincingly demonstrated otherwise.
Redating Mexico’s Toloquilla Footprints with optically stimulated luminescence
The peopling of the Americas is one of my favorite subjects in anthropology. Lately, we’ve seen a whole slew of studies that focus on this topic but through a genetic lens, the most impactful of which indicates that people began migrating to the Americas roughly 16,000 years ago.
But there are some inconsistencies with this date, especially the 325 foot-like prints found in Valsequillo Basin’s Toloquilla rock quarry in Mexico.
These footprints were within a soft, damp volcanic ash along a lakeshore shortly after a volcanic eruption. This type of volcanic tuff is known as the Xalnene. Samples of the Xalnene tuff were sent off to the Berkeley Geochronology Center for argon-argon and paleomagnetic dating. The results, published in this 2005 Nature study, “Age of Mexican ash with alleged ‘footprints’,” indicated the ash layer to be 1.3 million years old, making many wonder as to whether the indentations were even made by humans.
The team that initially found the prints have revisited the dating of the Xalnene tuff at Toloquilla. They say that the ‘dating of the ash is complicated by the fact that an eruption occurred underwater.’ The team reanalyzed the tuff by optically stimulated luminescence (OSL), a method that requires sampling deep within the tuff and in complete darkness. The samples are then irradiated with an atomic reactor and when ultraviolet light is shone onto the irradiated samples, the resulting fluorescence reveals how long it has been since the rock was last exposed to sunlight—or volcanic heat.
The results of the OSL redating were shared at last week’s meeting of the American Geophysical Union in Florida. Right below the ash, the sediments date to 70,000 and 100,000 years old. The sediments above, date to 9,000 to 40,000 years old. With this time range, it is possible to confer the OSL dates with carbon-14. The team did just that, radio-carbon dating the ages of shells in the sediments above and below the ash layer. The dates of all three layers therefore suggest the footprints were made about 40,000 years ago.
This date indicates humans were in the Americas 25,000 years before the coalescence dates from the most recent genetic studies, and 27,000 years before the Clovis culture. So it begs one to ask if the foot prints are even made by humans? The team scanned the foot prints with a laser scanner and constructed images to compare to footprints made by volunteers trotting on a beach in the United Kingdom.
Ultimately, this study challenges argon-argon and paleomagnetic dating. Paul Renne, of the University of California, Berkeley’s Geochronology Center and Rafael Suárez of the Museo Nacional de Historia Natural y Antropología in Montevideo, Uruguay both are critical… they wonder why there isn’t an archaeological record for 27,000 years.

4,000-year-old frozen hair mtDNA sequenced from a Greenlandic Saqqaq settlement. Pt. II
A bit belatedly due to my relocation to Boston, I’d like to contribute a few observations regarding the phylogenetic position of the mtDNA sequence uncovered from a 4,000 year-old lump of hair in Greenland. Kambiz has already reviewed this Science article, hence the readers should have a good idea of what it took to obtain this valuable piece of ancient DNA.
Although Gilbert et al. (2008) claim that the ancestry of this sequence is unique and goes directly back to Siberian populations, I don’t think this statement is borne out by facts. First, they overlook the fact that the clade D2 is divided between Na-Dene (D2a), Aleuts (D2b) and Eskimos (D2c). The fact that D2a is found in Na-Dene populations all the way down to the Apaches (see Derbeneva et al. 2002. “Analysis of mitochondrial DNA diversity in the Aleuts of the Commander islands and its implications for the genetic history of Beringia.” Am J Hum Gen 71: 415-421) is something the article completely left out.
Second, their claim that “D2 derives from an Asian-specific Hg D4e and not from any of the 5 Native American founding haplogroups (Hgs A2, B2, C1, D1 and X)” is based on confusion. On the one hand, D2 was reported among such Mexican groups as the Tarahumara and Nahua, with no recent relationship to Beringia (Penaloza-Espinosa et al. 2007. “Characterization of mtDNA Haplogroups in 14 Mexican Indigenous Populations.” Hum Bio 79 (3): 313-320). On the other hand, the confusion regarding the distribution and phylogeny of D lineages in the Americas has recently been reinforced by Tamm et al. (Beringian Standstill and Spread of Native American Founders. PLoS One 9 (2007): 2), who label the oldest known D sequence from the On Your Knees Cave on Prince of Wales Island, Alaska (10,300 YBP), as D4h3 and claim that it’s identical to a range of Native American groups distributed all the way from Alaska to Tierra del Fuego (Chumash, Tarahumara, Mapuche, etc.).
Gilbert et al. (2008) openly consider D1 a subset of D4. However what the On Your Knees Cave actually demonstrated is the fact the assignment of some sequences to either Asian-specific D4 or to Amerindian-specific D1 can be problematic, for these two subclades may stand in a sister relationship to each other (Kemp et al. 2007. “Genetic Analysis of Early Holocene Skeletal Remains from Alaska and Its Implications for the Settlement of the Americas.” Am J Phys Anth 132: 617). That’s how one can explain the apparent confusion created by the Tamm paper and the Gilbert paper, in which a D sequence found all over America is considered to be Asian-specific, and the relatively autonomous D1 clade is declared a subclade of D4.
An analogy with another ancient DNA study of the sequences from several individuals at China Lake, BC, which recorded a “modal” M lineage in prehistoric American Indians (Malhi et al. 2007. “Mitochondrial haplogroup M discovered in prehistoric North Americans.” Journal of Archaeological Science 34, 4: 642-648), may point to the same situation with the On Your Knees sequence. It’s one of the “modal” D sequences that predates the fission into D1 and D4 lineages in Beringia. Consequently, what Gilbert et al (2008) actually found was a sequence that doesn’t fall outside of American Indian and Eskimo-Aleut mtDNA variation (all the D branches from D1 through D4 may have representatives in the Americas), but constitutes an interesting survival of an ancient Beringian population with links to modern Aleuts and Na-Dene.
Although Beringia appears to be a late Pleistocene/early Holocene refugium and a genetic melting pot, it’s still unclear whether there was an identifiable migration from Northeast Asia to America. It’s more likely that Beringian hunter-gatherers trickled into interior Siberia (the so-called “Paleoasiatic” peoples such as the Chukchi and the Koryaks, but also the Kets, are the modern examples of this back-migration) as well as along the coast into Greenland. The fact that Gilbert et al. reported only one single sequence makes any further generalizations about the genetic layers in Greenland premature, for any random act of gene flow, transcultural adoption, or slave trade could account for its presence in the territories historically occupied by the Eskimos.
4,000-year-old frozen hair mtDNA sequenced from a Greenlandic Saqqaq settlement
A couple days ago Science published a peopling of the Americas paper. The paper is based on ancient mtDNA analysis of hair from a site in Greenland called, Saqqaq, also known as Qeqertasussuk, Disko Bay. The authors were able to identify a unique haplogroup, not shared by other Native Americans, which suggests that a different group from north Asia settled in what is now Greenland and then disappeared.
The paper is titled, “Paleo-Eskimo mtDNA Genome Reveals Matrilineal Discontinuity in Greenland.” The twigs associated with the site were dated by Carbon-14 to be roughly 4,000 – 3,100 years old. Four human long bones were excavated but were in poor condition. A clump of permafrost-preserved hair was also excavated. While hair is mostly made up of keratin protein polymers, the shaft of hair follicles often are an abundant source of well-preserved ancient DNA. 
The authors first honed in on this, first PCR amplifying, cloning and sequencing just the mtDNA HVS1 sequences. It was found that the hair derives from a single clade, Hg D2. D2 is shared with Aleuts of the Commander Islands as well as Sireniki, Yuit, Chukchi, Buryat, Khamnigan, Yakut, and Evenk peoples. Hg D2 is not found in any European and Inuit populations, and that determined that there was no contamination from the excavators.
Unlike the other ancient DNA paper we heard about earlier this week, the authors of this paper decided to sequence the complete ancient human mtDNA genome. The FLX sequencing-by-synthesis developed by 454 Life Sciences and Roche Diagnostics was used primarily, as well as traditional pyrosequencing for shorter segments. The genome was sequenced approximately 11 times over and approximately 16,497 bp of the 16,569 base pairs genome was assembled. All of the Hg-diagnostic SNPs they found in their first pass, the HSV 1 trial, were re-confirmed, further validating no contamination.
Comparing the Saqqaq genome to the Cambridge Reference Sequence indicated the Saqqaq differs at 40 SNPs. At these 40 SNPs, no detectable contamination or mosaic sequence variation was found. Comparing this nearly complete mtDNA genome to 300 complete Native American mtDNA genome sequences indicates that the Saqqaq sample is distinctly different from modern and ancient Neo-Eskimo people. From the paper,
“The sample is closely related to D2a1a, a common mtDNA haplogroup found among Aleuts, in particular those of the Commander Islands, who are descendants of a forced colonization of the Medny and Bering Islands in the mid 19th century. The sample is also closely related to a subset of the Siberian Sireniki Yuit. However, the Saqqaq sequence is unique, and does not share specific mutations with these groups (n.p. 8,910 for D2a1a and n.p.16111-16366 for D2a1b) but rather branches off of the root of D2a1 on the basis of two homoplasmic (n.p.14226-16092) and the putatively heteroplasmic (n.p.11234) private mutations.
Based on the contemporary Sireniki Yuit and Aleutian mtDNA data, the coalescence of the D2a1 clade was estimated to 2,000±3,400 years using the synonymous transition clock (23) or 7,500±4,500 years when the clock is calibrated over all coding region sites.”
This cladogram provided in the original paper documents the differences much better:
The observation that ‘Hg D2 derives from an Asian specific Hg D4e and not from any of the 5 Native American founding haplogroups,’ indicates to the authors that migrations that first lead human populations to colonize the far North of the New World all the way to Greenland first. This is not a crazy claim, we now know there were multiple migrations into the Americas and the current mitochondrial diversity of Native Americans indicates very few ancestral mothers, but with this new study we now know the diversity of Native Americans was at least diverse in at least one more lineage.

The Genius of Kinship: Human Kinship Systems and the Search for Human Origins
Thank you, Kambiz, for letting me introduce my new book to the Anthropology.net community.
The story behind The Genius of Kinship is an interesting one. In 1991, then a student of history at the St. Petersburg State University, I wrote a course paper on the traditional social organization of the Shoshone Indians as could be gleaned from ethnographies and trappers’ accounts. Why would a Russian student be interested in the Shoshone Indians is an entirely different story to be told on a different occasion. Let’s just say I was researching Shoshone Indians because they were not widely known in the Russian ethnological literature. My advisors apparently noticed my interest in pre-industrial social structures, and recommended that I explored Shoshone Indian kinship structure in greater detail next year. I poured over literature on kinship studies in Russian, French and English for a few months and then looked at Shoshone kinship again. I was struck by their logical consistency and by the fact that this elegant simplicity was not mentioned anywhere in the basic literature on kinship. Typical case studies came from Australia, Southeast Asia, Oceania, Sino-Tibetan languages, but not from North America.
I thought that was puzzling: kinship studies, as we all know, were founded in the mid-19th century by the American lawyer, Lewis Henry Morgan, on the basis on Iroquois and other North American Indian tribes/nations. The birth of kinship studies coincided with the birth of anthropology as a romantic quest for the origins of Western civilziation. But by the end of the 20th century American Indian kinship structures are nowhere that prominent. Possessed by a pioneer’s zeal, I ventured into kinship terminologies around the world and initially amassed a database of over a thousand kinship nomenclatures from many linguistic families. In 1997, I defended my research as a Ph.D. dissertation at the Peter the Great Museum of Anthropology and Ethnology in St.Petersburg, and in 2001 I published it as a book entitled The Phenomenon of Kinship. Without a particular premeditation, I followed in Morgan’s early footsteps when he wrote The Systems of Consanguinity and Affinity of the Human Family (1870) and conceived of kinship terminologies as a source of information about ancient human population dispersals. (Morgan as a famous social evolutionist emerged with the publication of Ancient Society in 1877 when he attempted to explain the diversity of human kinship structures as a matter of stages in the progressive maturation of humankind.) Over and over again, I caught myself thinking that American Indian kinship structures are unique and can provide a missing link for the evolution of Old World kinship structures.
When I came to the U.S. in 1997 as a Ph.D. student in Anthropology at Stanford, I faced another puzzling irony of history: it’s not just American Indian kinship structures that have been eclipsed from the anthropological agenda, American anthropologists were not doing kinship studies at all. As Sylvia Yanagisako said upon learning about my Russian research, “But nobody does this stuff here anymore.” Truth be told, she herself was part of a “revival” of kinship studies in the U.S. in the late 1980s but more along the lines of gender, with “kinship” being scowled at as a spurious Victorian invention. For some inexplicable reason, she was sceptical of kinship systems, structures, lineages, and especially terminologies. Speaking to other feminist professors at Stanford’s Department of Anthropology (later Department of Cultural and Social Anthropology) such as Jane Collier and Carol Delaney, I couldn’t figure out where all the good old kinship studies went. Where were Lowie, Kroeber, Radcliffe-Brown, Malinowski, Fortes, Levi-Strauss, Dole, Murdock, Tax, Scheffler, Lounsbury, Dumont, Allen, Barnes, Trautmann, Tyler, Kronenfeld, componential analysis, generative analysis, equivalence-rule analysis and other proud representatives of the anthropological tribe? Yanagisako, Delaney and Collier all referred me back to David Schneider who allegedly “proved” that “kinship” was a malignant excresecence on the body of the discipline manifesting all the imaginable vices from racism and colonialism to the masculine bias.
It didn’t make much sense: coming out of a former Soviet country with all its anti-racism and anti-colonialism and anti-capitalism-with-its-severe-exploitation-of-women-and-children, I still felt okay about kinship. Of course, it’s a tough field, not for everyone, but anthropology and kinship are inseparable. You can critisize, develop new theories, change paradigms, but still groom the central concept of the discipline. That’s how I felt.
Across the Main Quad at Stanford, another group of American anthropologists was setting up a different anthropology department called “Anthropological Sciences.” Jim Fox was teaching anthropological linguistics, Joanna Mountain population genetics, Merritt Ruhlen Greenberg’s multilateral comparison, Bill Durham general evolution. There was no kinship studies either, but at least Tom Trautmann once came in with a talk, Hill Gates asked me about the Russian kinship theorist, Mikhail Kryukov, and Joanna Mountain heard about African “segmentary lineages.” Needless to say, the Anthropological Sciences people were very much into out-of-Africa theory of human evolution. Correspondingly, they were supporters of Clovis-I in the Americas. I took classes with Joanna Mountain and worked in her genetics lab. She was a student of Luca Cavalli-Sforza. I also heard wonderful presentations from Richard Klein on African fossils, Peter Underhill on Y chromosome, Marcus Feldman and Lev Zhivotovsky (a Russian geneticist from Moscow) on autosomal markers, and Joe Greenberg on the peopling of the Americas. When Greenberg passed away in 2001, Christie Turner flew in from Arizona for the memorial conference, only to reiterate the “consensus” between his odontology and Greenberg’s linguistics as a rock-solid proof of a recent origin of American Indians. (By 2005, Matsumura and Hudson in “Dental Perspectives on the Population History in Souteast Asia” //
American Journal of Physical Anthropology 127 deconstructed Turner’s celebrated Sundadonty category as a result of relatively recent admixture, thus depriving his general theories of much of their power.) In 1997-1998, Tom Dillehay’s Monte Verde was coming into spotlight, and John Rick grudgingly accepted Dillehay’s dates, with a caveat that “Tom probably mixed up the strata” but now it’s too late to disprove his Monte Verde tome.
So, I was caught in a cross-fire: on the one hand, feminists and post-structuralists “proved” that kinship studies was the unfortunate invention of the confused Cro-Magnon male; on the other hand, archaeology and genetics from across the Quad “proved” that humans came from Africa some 50,000 BP and peopled the Americas no earlier than 11,500 BP (okay, 12,500 BP but Dillehay must have confused the layers). In 1986, Greenberg tried to endorse the latter view linguistically with his tripartite division of American Indian languages into Amerind, Na-Dene and Eskimo-Aleut. (This classification was eventually rejected by the actual specialists in American Indian languages, and with it went down the linguistic counterpart of the out-of-Africa model.) But there was a gap between molecular genetics and linguistics, namely demography, social structure, marriage practices, residence patterns and kinship terminologies. Only this sociocultural bit of evidence could imbue our human origins story with necessary realism. I thought kinship studies could definitely furnish this missing link, and whether human kinship is about “biology” or about “culture” was an utterly secondary matter. I was contemplating terms like “idenetics” and “gignetics” (from Greek gigno ‘to give birth’, a cognate of gen-) to dub this mature state of kinship studies in the 21st century.
Human origins and dispersals research in the 1980s-1990s was driven by “physical” disiplines, those being archaeology/paleontology and genetics. Sociocultural data, meaning linguistics, kinship systems, mythology, were lagging behind. As late as 1980, Robert Austerlitz published a paper in a highly-specialized linguistics periodical called Ural-Altaische Jahrbucher calling attention to the fact that American Indians harbor much more linguistic diversity than the Old World. In 1992, Johanna Nichols published Linguistic Diversity in Space in Time and concluded that our perspective on early human languages comes from America and Australia/Oceania and not from Africa and Europe. Sociocultural anthropology was supposed to contribute kinship studies to the growing interdisciplinary effort, but it forsook it for the sake of abstract ethical polemics. This is all the more bizarre and unfortunate, since anthropology had been working with worldwide databases of kinship terminologies and forms of social organization long before blood groups were discovered, never mind mtDNA sequenced. (In 1967, Murdock sampled 800 kinship terminologies for the patterns of sibling nomenclature that gave a pretty good overall resolution of what patterns are found on what continents.) And the futility of post-modernist moralizing was vividly manifested “across the Quad,” where any reflexivity was tantamount to heresy. Both versions of anthropology looked equally sterile to me.
As a true patriot of Stanford’s Anthropology, I escaped the split of the department into Cultural and Social Anthropology and Anthropological Sciences by migrating for two quarters to the University of Chicago. I listened to terrific Terry Turner on the Kayapo, the late Kostas Kazazis on Indo-European historical linguistics and Balkan dialectology, flamboyant Michael Silverstein on evidentiality, and cowboy-hatted Ray Fogelson (once Yanagisako’s professor at the University of Washington) on American Indian studies and psychological anthropology. I saw legendary Marshall Sahlins from behind and narrowly missed Eric Hamp and Paul Friedrich. And lo and behold, Tom Dillehay himself was there teaching “Andean Prehistory” for half-a-year from the University of Kentucky. For his class, I wrote a paper suggesting that a crucial piece is missing from our human origins research (namely, kinship systems and related linguistic typology), that the out-of-Africa theory is quick and premature, and that if we look closely at American archaeology we won’t be able to see the exact process by which an adventurous group of Siberian hunters colonized the Americas. Symptomatically enough, Cavalli-Sforza assumed a relatively recent entry into the Americas in order to substantiate his claims of an African origin of modern humans; genetically, American Indians and Africans are polar opposites, hence, if we know that America was peopled late, then we can be sure that Africa was the cradle. Looking at Pleistocene archaeology with a critical eye leads one to believe that the data can’t exactly justify using America as an inverted yardstick for Africa. Clovis tools are found everywhere in the Americas but not in Siberia; microblades are found everywhere in Siberia from 20,000 BP but in America they never penetrated south of the Vancouver Island.
Dillehay gave me an A-, and put me in touch with a fellow out of California by the name of Alvah (Pardner) Hicks who’s been trying for a good decade to convince people to look at America as a possible homeland of modern humans. Hicks was in the midst of the 1990s hoopla around the peopling of the America: he attended conferences, dated skulls in South America, corresponded with Tad Schurr, Dave Meltzer and Lou Binford, buttonholed Lyle Campbell and Emoke Szathmary and summarized a myriad of human origins-related scholarly articles for the Mother Tongue readership (kinda doing blogging before blogging became popular). He tried his best to at least make people consider the possibility that American Indians could have migrated into Siberia at the end of the Ice Age. (Franz Boas talked about it a hundred years ago after the Jesup expedition.) But scholars simply refused to listen to Hicks: he brought to the table wacky ideas and he didn’t have a Ph.D. Nevertheless, Dillehay put me in touch with Hicks probably because I had one extra Ph.D. to give away.
When I returned to Stanford in 1999, I rushed to the library to update my kinship terminological database. The Russian library resources are no match for the Stanford ones, and the several years I spent at Green library comparing kinship terminologies from America, Africa, Oceania, Australia and Eurasia were totally worth it. I dug into obscure Brazilian Ph.D. theses, old French dictionaries of rare Austroasiatic languages and Joe Greenberg’s own collection of African language studies. In the end, I assembled a database of some 2500 languages, diligently assembled a comprehensive bibliography and screened this sample for a bunch of typological markers, such as self-reciprocal terminology, “Crow-Omaha,” sibling nomenclature, formal morphology, etc. Some of these typological/polysemic markers were well-known in the literature, others I had to describe anew. When the ordeal was over, I realized that my initial findings were reinforced and bolstered. American Indian kinship terminologies are archaic, while African kinsip terminologies are transformed.
This is the central thesis of The Genius of Kinship. But it’s not the only one. I introduce the reader into the history of kinship studies within and outside of anthropology, compare the ideas about kinship held by Morgan, Darwin and Lyell and conclude (very much in a post-structuralist vein) that our 19th century ideas about human kinship influenced our ideas about human origins. We looked into archaeology and paleontology for answers to the questions of where we came from, while outright dismissing evidence from living human populations (language, kinship, folklore). We were interested in what was left behind in a garbage pit, not in what was passed down to the next generation. We sought our origins in Neandertals, while letting American Indians pass into oblivion. We bypassed American Indian linguistic diversity and grammatical uniqueness and declared them a “recent” population in virtue of the fact that no fossil hominids were ever found in the Americas.
The Genius of Kinship is not meant to be an advocacy for an out-of-America theory of human origins and dispersals. This is a gigantic task. Rather, it’s a revival of kinship studies in anthropology in conjunction with the recent advances in linguistics, psychology, sociology and historiography, a nitty-gritty typological analysis of a large sample of kin terminologies and its application to the prehistory of such accepted language families as Na-Dene, Austronesian and others. One of the results of this revival is a suspicion that the 150 years of finagling with anthropological knowledge (are Indians savages? shall we continue with kinship or shall we switch to gender? only archaeology can furnish reliable data, let’s look at Neandertals, languages are too difficult to comprehend, while we need something tangible to look at, etc.) has resulted in a confused picture of human origins and dispersals in which fundamental assumptions remain unproven, while every new piece of evidence is either swept under the carpet or instantly reinterpreted to fit the consensus.
For instance, the original mtDNA paper, namely “Radiation of Human Mitochondrial DNA Types Analyzed by Restriction Endonuclease Cleavage Pattern” published by Johnson, Doug Wallace and Cavalli-Sforza in the Journal of Molecular Evolution 19 (1983) clearly showed that American Indians have the highest frequency of the ancestral human mtDNA “morph combination” (That was a restriction-site analysis, but still it provided a foundation for all subsequent research, the only difference being that at some point the tree was flipped around and the Africans were declared the oldest population.) The tree topology in this early paper bears close resemblance to the map of human blood types, with American Indians being preponderantly type O. Now, match Johnson et al. (1983) with Ward et al.’s (1992) intriguing paper on extensive mtDNA diversity among the Nuu-Chah-Nullth exceeding that of African !Kung, and ponder as to why American Indians are widely considered to be a young population. In order to explain away an inconvenient fact, Ward et al. had to resort to an argument that American Indians brought this diversity with them from Siberia. Now that pre-Clovis coprolites attest to the antiquity of mtDNA A and B lineages in North America (see Gilbert et al. Science 320 [5877], 2008), even The Onion is smart enough to ridicule Ward et al.’s logic when it writes: “How can we be sure that some ancient nerd didn’t just carry an already thousand-year-old petrified turd with him when he crossed over the land bridge from Asia?”
Or, take Edward Vajda’s recent discovery of a linguistic connection between an isolated Siberian language, Ket, and Na-Dene in North America. The system of verbal prefixes is better preserved in Na-Dene than in Ket, the Ket sibling terminology is radically transformed from its Na-Dene prototype (The Genius of Kinship, p. 325). Or, the fact that the Kets’ neighbors, the Selkups and the Evenkis have a subtype of the purely American Indian mtDNA haplotype A2 (Tamm et al. Beringian Standstill and the Spread of Native American Founders. PLoS One, September 2007, no. 9). Isn’t it a genetic illustration of Boas’s and Hicks’s “back-migration”? While we find traces of American Indian genes in Siberia, the reverse isn’t true: we haven’t found such a close variant of a Siberian gene in the Americas. Or, if one reads Russian and opens up Vladimir Napolskikh’s dissertation on the Earth-Diver myths in America and Siberia, a simple scheme shows that all the archaic variants of this widely-spread motif are in North America, while all the derived ones are in Siberia.
There’s a puzzling contradiction in our data (if this data is looked at through unbiased interdisciplinary lenses), namely that “physical” disciplines such as archaeology/paleontology find lots of support for out-of-Africa, while “ideational” disciplines such as linguistics and kinship studies have Africa as a secondary spread zone and not a homeland. Which data should we trust? Can we ever hoe to build a robust theory on the basis of archaeology’s always-fragmentary-and-accidental evidence? Or, as Eldridge ad Gould famously claimed, such a theory can only be built on the basis of data coming from living biota? How do we now that the currently popular out-of-Africa interpretation of mtDNA and Y chromosome data is not simply a theoretically possible scenario and and the adaptation of a new system of information to suit the existing archaeological/paleontological consensus but a true description of unique population events? All our population genetic maps show the world at 1492, when Africa was probably genetically most diverse, but by 2008 America is arguably the most diverse continent: what scenario of human evolution would we develop hundreds of years from now provided that we wouldn’t know upfront that America was peopled from Europe, Asia and Africa after 1492? We dismissed America as a “New World” and its inhabitants as an Asian offshoot back in the 16th century, which is long before any scientific evidence has been accumulated, but can we reject the possibility that our modern archaeological, genetic, linguistic and ethnological data is consistent with two opposite “single-origin” scenarios? If so, can we rationally adjudicate between the two scenarios without demolishing one as “wacky” and then using the rubble to lionize the other?
