Beyond bones & stones
This volcano in East Africa, called Ol Doinyo Lengai, erupted long ago and produced a mudflow that preserved the biggest collection of ancient human footprints (some shown in the foreground) found in Africa so far. Cynthia Liutkus-Pierce Just south of Lake Natron, in northern Tanzania is the Engare Sero site which was was originally discovered... Continue Reading →
Most associate dark skin with African peoples, but there are a wide variety of populations who represent an even wider array of skin tones, from the light beige skin of the San to the deep black skin of the Dinka. A new study published online this week in Science, identifies a handful of new gene variants responsible... Continue Reading →
If you have noticed there is a paucity of ancient DNA studies from Africa. I'm not entirly sure why. Part of it can because there simply are not as many samples from the African fossil record as ancient DNA decays rapidly in warm, moist climates. Europe samples are sometimes found in cold, dry caves. And... Continue Reading →
This November, a team funded by National Geographic and led by Lee Berger of the University of Witwatersrand in Johannesburg made a huge find. 1200 hominin skeletal elements were recovered from a South African cave, representing at least 12 individuals. Human remains are pretty rare, and this one site contains more human fossil material than... Continue Reading →
This has been done before using H. pylori as a model, but it is remarkable nonetheless to see how innovative researchers are in using different models to track human migration patterns... this time with HSV 1 or human simplex virus 1. For the study, which is published in the open access journal PLoS ONE, the... Continue Reading →
A complete 1.8 million year old skull found from Dmanisi, Georgia could be evidence that early hominids are actually all members of a single species. Researchers published their analysis in Science today and argue that the skull’s combination of primitive and more evolved features, such as a small braincase (546 cubic cm) with a large...

Nature Communications published an article in May, 2013 that just now caught my eye. The paper's title, "Development of Middle Stone Age innovation linked to rapid climate change," lays down a solid understanding of what the authors found... The one line summary of the article is: the authors observed that very abrupt changes in rainfall... Continue Reading →
The most comprehensive look at the genome of Africans is published in the journal Cell today. The paper titled, "Evolutionary History and Adaptation from High-Coverage Whole-Genome Sequences of Diverse African Hunter-Gatherers," focused on three hunter-gatherer populations; Pygmies from Cameroon and two groups from Tanzania, the Khoesan-speaking Hadza and Sandawe. The publication covered each of the genomes of five... Continue Reading →
This month in the Journal of Human Evolution, a new study on the teeth of the Dmanisi Homo erectus has been published. A site in the Republic of Georgia, Dmanisi has yielded a vast quantity of hominin fossils dating to approximately 1.8 million years ago—even an elderly individual without teeth. The discovered crania are remarkably... Continue Reading →
