Neandertal ancestry, going, going, ..., gone (?)

A deluge of new data from Upper Paleolithic Europe will give us all a lot to think about. It is incredible that Neandertal ancestry seems to have decreased over time in Europe (Oase1 is off-cline with lots of extra Neandertal ancestry from a recent genealogical Neandertal in the family tree).

More on Kennewick Man

A new technical report re-analyzes the data of Rasmussen et al. study on Kennewick man and confirms that he is related to Native Americans. From the report:We find the Kennewick sample has the highest shared similarity to Native American...Show More Summary

Bursts in human male demography

From the paper:When the tree is calibrated with a mutation rate estimate of 0.76 × 10-9 mutations per base pair per year9, the time to the most recent common ancestor (TMRCA) of the tree is ~190,000 years, but we consider the implications of alternative mutation rate estimates below.

Periods of human activity in Chauvet-Pont d'Arc cave

PNAS DOI: doi: 10.1073/pnas.1523158113 A high-precision chronological model for the decorated Upper Paleolithic cave of Chauvet-Pont d’Arc, Ardèche, France Anita Quiles et al. Radiocarbon dates for the ancient drawings in the Chauvet-Pont d’Arc Cave revealed ages much older than expected. Show More Summary

Nubian assemblages from the Negev

Nubian assemblages from the Levant are quite important because they provide an intermediate link (along land routes) between those from Africa and Arabia. It's also more difficult now to consider the Arabian finds as a limited event without broader implications about modern human dispersals. Show More Summary

Neandertal Y-chromosome (finally)

It's been six years since the publication of the draft Neandertal genome, and one piece of the puzzle that's always been missing is the Neandertal Y-chromosome (unfortunately most of the Neandertals yielding data were female). But, the...Show More Summary

Zhiren cave human remains: 116-106 ka old

Quaternary International doi:10.1016/j.quaint.2015.12.088 The age of human remains and associated fauna from Zhiren Cave in Guangxi, southern China Yanjun Cai et al. Zhiren Cave in southern China is an important site for the study of the origin and the environmental background of early modern humans. Show More Summary

Denisovan ancestry in Oceanians (and some in South Asians)

Current Biology DOI: http://dx.doi.org/10.1016/j.cub.2016.03.037 The Combined Landscape of Denisovan and Neanderthal Ancestry in Present-Day Humans Sriram Sankararaman et al. Some present-day humans derive up to ?5% [ 1 ] of their ancestry from archaic Denisovans, an even larger proportion than the ?2% from Neanderthals [ 2 ]. Show More Summary

Bronze Age war in northern Germany

Slaughter at the bridge: Uncovering a colossal Bronze Age battle About 3200 years ago, two armies clashed at a river crossing near the Baltic Sea. The confrontation can’t be found in any history books—the written word didn’t become common in these parts for another 2000 years—but this was no skirmish between local clans. Show More Summary

Neandertal and Denisovan DNA from Melanesians

Admixture models are out of control these days, with 4 inferred archaic introgressions into three groups of Eurasians (Europeans, East Asians, Melanesians). The model on the left has to be a simplification/incomplete/wrong in some way...Show More Summary

Are living Africans nested within Eurasian genetic variation (?)

The picture on the left (source) shows quite nicely that according to current understanding, Africans are nested within Eurasian genetic variation. The modern humans have the following structure:(Early modern human lineage detected as...Show More Summary
