Evolution 101: People Don’t Look Like Goats
On the lighter side of anthropology… The Onion takes a satirical look at what outrageously pseudoscientific research into human origins might look like. Their headline reads:
“Anthropologists Trace Human Origins Back To One Large Goat”
‘Wait, That Can’t Be Right,’ Scientists Say”
In addition to being funny, the article, by contrast, helps show the strict standards of evidence, interdisciplinary collaboration, and peer-review process of actual paleoanthropological research. Also, our close relationship with other primates is highlighted when one fake Onion researcher observes that “…humans don’t look like goats.” In other words, don’t expect any presentations on “goat people” at professional anthropological conferences anytime soon. Enjoy!

Anon & Anthropology of Hacking
Anonymous is not a force to be reckoned with. Scientologists have felt their wrath for sometime, Sarah Palin did as well, as have MasterCard & Visa post-Wikileaks fiasco. I’m sure Aaron Barr is now realizing the impact Anon has. Aaron Barr is head of an internet security company, HBGary Federal. His company was contracted by Bank of America as a counter Wikileaks impending release of cables that will incriminate BofA.
Anon vs. Scientology
Ars Technica has written up a 3 page account of the situation, which is absolutely fascinating. The tl;dr seems like its comes straight out of a B movie. Aaron’s ingenious plan was to ‘infiltrate’ Anon…He joined IRC channels in an attempt to sabotage Anon and get names of those in the organization.
His problems started here. Aaron failed to realize Anon is not a true organization. At its core, Anon is an anti-organization, as anarchist as you can be, with no leadership and an ever-changing membership. Aside from infiltrating the chat groups, Aaron attempted to flesh out members of Anon via a guilt-by-association method using something akin to 6-degrees-of-separation and social media. He revealed himself to the group, claiming to research them.
What ended up completely backfired on Aaron. Anon was pissed. In traditional hacking manner, they hacked his company’s site and replaced the front page. They also managed to get a hold of at least 44,000 of his emails and release them via torrents. They deleted 1 TB of his backups, wiped his devices and to top it all of, got a hold of his Twitter and LinkedIn accounts where they posted messages as him. For a company that was in the midst of a sale, Anon effectively ruined that.
This leads me to a open up a discussion regarding the Anthropology of Hackers, a timely piece that appeared in the Atlantic yesterday by NYU’s Gabriella Coleman. In her write up she outlines her 13 week curriculum on the culture of hacking, covering topics like open source, privacy & anonymity, and the dawn of the nerds. Ironically, almost all are relavent to HBGary Federal, given Aaron’s troubles. I wonder how they’d benefit from a crash course in Coleman’s class. Looking at Coleman’s course topics, there’s a lot to consider regarding hacking. The most relevant to this topic is the material covered in Weeks 11 & 12,
Week Eleven: Anarchism and the Politically Minded Hacker
Many hackers express some degree of ambivalence over the politics of hacking as Patrice Riemens has argued and as hackers themselves have raised. This is not the case with a small but well organized cadre of hackers located primarily in Latin America, Europe, and North America who havecharted collectives, many of them influenced by the political philosophy of anarchism. To grapple with anarchism as a political philosophy (which, similar to hacking, is plagued with a parade of misconceptions), we turn to David Graeber‘s fantastic pamphlet, Fragments of an Anarchist Anthropology. We also read Jeff Juris’s ethnographic work about technology activists during the counter-globalization era Networking Futures.
Week Twelve: Trolls and the Politics of Spectacle
If anyone has been paying attention to the Internet in recent years, it has been impossible to miss a class of provocateur and saboteur: the Internet troll, whose raison d’être is to be as offensive as humanely possible via raunchy (but often humorous and quite esoteric) language, images, pranks, and tricks, basically, doing it for what they call the “lulz.” To get a sense of the cultural logic and exploits of trolls we read “The Trolls Among Us” by Mattathias Schwartz. To help us grapple with the nature of spectacle, we read a couple of chapters of Dream: Re-imagining Progressive Politics in an Age of Fantasy by Stephen Duncombe. We read excerpts from Lewis Hyde’s magnificent book on tricksters to consider whether the troll might be an example of these mythical creatures that have dazzled countless societies with their trickery. We watch a talk on a protest movement against the Church of Scientology whose roots lie in the act of trolling buteventually turned into a morally serious protest movement, which nonetheless retained the tactics of spectacle as part of its political arsenal.
This is a very interesting time to be looking at the intersection of technology and culture. There are anthropologists doing some fascinating work researching the sense of identity in online communities like World of Warcraft and Facebook… These groups share an online space, often with avatars and complex long-lasting interactions.
But with Anon there’s no identity.
Anon remains behind ever-changing screen names and masked localities behind proxies. I’m sure if you’ve ever taken an Intro to Cultural Anthropology course you would have touched on Erik Erikson’s theories of personality, We know what defines identity is a loose association of markers like behavior, language, dress, shared spaces, etc. Anon is disparate to any modern definition of identity. They do not share the same space, language, or any other measure of similarity except for behavior and ideology…
“We are Anonymous. We are Legion. We do not forgive. We do not forget. Expect us.”
I’d really like to get to hear Coleman’s take on this current event, or any cultural anthropologist for the matter. So if you’re interested, please chime in on your take on this all — What do you understand on Anon and how are they similar/dissimilar to other groups?
The Arched Metatarsal of Australopithecus afarensis
Carol Ward1, William Kimbel, and Donald Johanson have published a paper in Science on the arch seen in a newly discovered fourth metatarsal of Australopithecus afarensis (AL 333-160). A lot of the popular press are publishing misleading headlines that this proves bipedalism in australopithecines. No, we’ve known they were bipedal — we just didn’t have a true idea as to what extent they were bipedal. So a find like this helps investigate the degree of bipedalism.
AL 333-160 left fourth metatarsal in dorsal, lateral, medial, plantar, and proximal views.
How does this tell us how bipedal A. afarensis were?
) Box plots of angular relations of the proximal and distal metatarsal ends to the diaphysis in chimpanzees, gorillas, humans, and AL 333-160.
If you’ve ever had the pleasure of visiting a podiatrist, you’d know flat feet are not conducive to bipedalism. The two-way arch helps support upright walking and distribute recoil force. Other great apes like, chimps and gorillas have flatter feet than us. The authors of this paper confirmed this by comparing the fourth metatarsal of chimps, gorillas, and humans to AL 333-160.
On all their comparisons, AL 333-160 fell within range of humans. There were some occasions where there’s a lot of gray area which I’ll address later. Nonetheless, to the right you can see the best comparison, in my opinion, which the comparison of the arch of the diaphysis of the bone between the two species. You can have a look at the rest of the figures here.
The problem I am seeing here is that this metatarsal is not Lucy’s (AL 288-1). AL 333 is designated to fossils from the site where the “First Family” came from and not the same locality as AL 288. Nonetheless, they are not the same individual. Kimbel is quoted in the BBC News, saying,
“Lucy’s spine has the double curve that our own spine does,” Professor Kimbel said.
“Her hips functioned much as human hips do in providing balance to the body with each step, which in a biped of course means that you’re actually standing on only one leg at a time during striding.
“The knees likewise in Lucy’s species are drawn underneath the body such that the thighbone, or femur, angles inwards to the knees from the hip-joints – as in humans.
“And now we can say that the foot, too, joins these other anatomical regions in pointing towards a fundamentally human-like form of locomotion in this ancient human ancestor.”
This is a flawed association to make; a form of what I would call confounding bias. We don’t have Lucy’s 4th metatarsal to see what it looks like and unfortunately we don’t have the rest of the this specimens skeleton to say it looked like Lucy’s. In fact, we have very little australopithecine appendicular and skeletons other than AL 288-1 (most notable are AL 129-1 and STS 14). So how can Kimbel say that the foot joins other anatomical regions when we don’t know what the other regions really looked like?
See, the n of this sample is 1. Looking at the intervals in the figures, especially Fig 3 & 4, there a a significant amount of variation in humans and chimpanzees that overlap. Chimps aren’t bipedal but we are. So imagine you are a paleoanthropologist way in the future looking at one metatarsal of a now-current then-ancient chimpanzee way and comparing it to a humans — surely you could make the same conclusion as these three have. And herein lies the big issue with sensationalism… as is the problem often in paleoanthropology, we just don’t have many comparative samples but people want definitive conclusions.

Neandertal Social Groups
Very rarely is an entire family group of hominins buried and fossilized at the same time. It is even rarer for paleoanthropologists to discover such an assemblage. Fortunately for science but unfortunately for the hominins, caves occasionally collapsed on entire social groups.
Map of El Sidrón
At a site known as El Sidrón in Spain, excavations have been ongoing since 2000. To date, 12 Neandertals have been discovered in a context that points to a single geological event, circa 49,000 years ago. A group of 12 Neandertals is consistent with previous estimates of around 10 individuals per group. At least six adults, three adolescents and four younger individuals were buried at once, most likely during a storm. The cold conditions of the cave system and immediate burial of the remains not only preserved the bones well, but were also ideal for DNA.
The remains were sexed based on both morphology and DNA analysis. After sex was determined, anthropologists identified the different Neandertal lineages based on mitochondrial DNA. Several of the adults were found to be male, and the other three female. It was discovered that all three males belong to the same matrilineal group, while each respective female has a different haplotype. When compared to modern Europeans, the authors noted that there is significantly less genetic diversity within the mitochondrial genome.
These results strongly imply that Neandertals exhibited patrilocal mating behavior. Females were the ones who would have changed family groups, not males. This type of insight into an extinct species is unique, thanks to the quality of DNA preservation available at El Sidrón.
Another interesting point of discussion in the study relates to Neandertal interbirth interval. One of the females was linked by DNA to two of the younger individuals, approximately several years apart in age. If the anthropologists are correct about the relationship, this puts the interbirth interval for Homo neanderthalensis at a value similar to hunter-gatherer groups today. This data, if replicated with other Neandertal individuals, could eventually dispel differential reproduction as a potential cause for Neandertal disappearance.
Knowing about Neandertal group dynamics could provide crucial clues as to why they went extinct. Future analysis of the remains recovered at El Sidrón will no doubt give more insights into our closest extinct relatives, and perhaps even why Homo sapiens flourished and Neandertals declined.

Do Archaeologists Care About the Living?
Do archaeologists care about the living? Yes, but like all people, we focus on those aspects of a story that are of greatest interest to us. That’s why I have tuned out much of the news coming out of Egypt over the last few weeks. I casually skimmed through articles about the protests, the motivations of the protesters, political ramifications for the region and for me as an American, and even the tragic loss of life. But when Egyptian antiquities were endangered, I began to pay close attention! As a kid, I was inspired by Indiana “It belongs in a museum” Jones. What happens when the museums themselves are threatened? Archaeological materials are one of the many casualties of war and civil unrest, as recently seen in Iraq.
During the Egyptian protests, the Cairo Museum, one of the most significant repositories of artifacts in the world, was raided by looters. Thankfully, it appears that none of the museum’s famed mummies were damaged and, in fact, some protesters defended the museum from looting. Dr. Zahi Hawass, head of Egypt’s Antiquities Department, even ridiculed some looters for stealing souvenirs from the museum gift shop while leaving priceless artifacts untouched. It could have been much worse, since the museum’s collections are truly irreplaceable, and their theft would’ve represented a great loss to humanity.
From the perspective of archaeological preservation, it was a relatively happy ending. Wait…was I really more outraged by the prospect of stolen artifacts and ransacked mummies than hundreds of deaths? Maybe 24-hour global news cycles have desensitized me to death tolls and modern human tragedy. Archaeologists, especially, have been accused of insensitivity toward living people (insert your own joke about archaeologists “preferring their informants dead” here). Sometimes this reputation is deserved – long hours poring over bones and stones in laboratories can dull a person’s sociability. But archaeologists are anthropologists and, as the anthropology.net motto says, we go “Beyond bones & stones.” Archaeologists are as focused on people as any other branch of anthropology. We reconstruct past human behavior from material remains, work with living and descendant communities to better understand the past, and do our best to share archaeology with everyone. Ideally, we go into anthropology because we are human beings who care about our fellow human beings, past and present. And, if our priorities sometimes need adjusting, world events remind us to pay attention to living people and dynamic political situations in addition to mummies.

Survival International & Uncontacted Amazonian Tribes
Anyone remember 2 years ago, when Survival International released some photos of an uncontacted tribe at the border of Brazil and Peru? Well an update came out, a remarkable video showing the tribe and describing what’s being done to protect them. Oh and by the way, this is part of BBC’s Human Planet.
The Fate of Arabian Archaeology
Image by Omar A. via Flickr
I stumbled upon this news piece in The Times regarding archaeology in Saudia Arabia. I wanted to share it with you all because of last week’s discussion of handaxes from the neighboring UAE. The article describes how archaeologists have been using Google Earth to survey for sites and have identified possibly 2,000 or so potential ones in Saudia Arabia. Now using Google Earth to do some armchair archaeology is nothing new really, there are examples from 2005, 2006, 2008 and 2010.
But we all know how strict Saudia Arabia is. One of their many impositions has traditionally been against archaeology — fearing that discoveries may disrupt the foundation of it being a cradle for Islam. From the article,
David Kennedy, a professor of classics and ancient history at the University of Western Australia, used Google Earth satellite maps to pinpoint 1,977 potential archaeological sites, including 1,082 teardrop shaped stone tombs…
…But few archaeologists have been given access to Saudi Arabia, which has long been hostile to the discipline. Hardline clerics in the kingdom fear that it might focus attention on the civilisations which flourished there before the rise of Islam – and thus, in the long term, undermine the state religion.
In 1994, a council of Saudi clerics was reported to have issued an edict asserting that preserving historical sites “could lead to polytheism and idolatry” – both punishable, under the Kingdom’s laws, by death.
This is not surprising to many. What is surprising was this tid bit:
Saudi Arabia’s rulers have, in recent years, allowed archaeologists to excavate some sites, including the spectacular but little-known ruins of Maidan Saleh (Correction its really Mada’in Saleh), a 2,000 old city which marked the southern limits of the powerful Nabataean civilisation.
For the most part, though, access to ancient sites has been severely restricted.
There are a lot of examples where traditions, governments, etc. get in the way of phenomenal discoveries. However, there are few where objection relaxed. I’m hopeful we’ll see more archaeology conducted on the Arabian peninsula, but I’ll think we’ll be seeing more from the more liberal areas like the Emirates.
