Oase1 had a Neandertal ancestor no earlier than ~200 years before his time

Several important conclusions of the discovery that Oase1 had a Neandertal ancestor 4-6 generations before his time (37-42 thousand years ago): This is a smoking gun that modern humans interbred with Neandertals, following up on theShow More Summary

DNA from hot climates technically feasible

From the paper: Ten petrous bones were selected from archaeological specimens, representing a wide range of geographical locations and climatic contexts (Table 1, for repository information see S1 File). The specimens were selected from Central Europe, Central Asia, Southeast Asia, the Levant, Anatolia, and North Africa. Show More Summary

Into, out of, and across the Eurasian steppe

A new paper in Nature adds to the earlier study in the same journal by presenting data from 101 ancient Eurasians. The year is not yet halfway over, but it seems that the ancient DNA field is moving towards a new norm of studying dozens...Show More Summary

101 ancient genomes from Bronze Age Eurasia

New data has been posted online. This seems related to this earlier post. Hopefully the study linked to this data will appear soon, but genome bloggers can get to it thanks to the early data release.Investigation of Bronze Age in Eurasia by sequencing from 101 ancient human remains.

East Africa is a strategic region to study human genetic diversity due to the presence of ethnically, linguistically, and geographically diverse populations. Show More Summary

Out of Egypt or Out of Ethiopia?

I am skeptical that once you remove non-African ancestry from Egyptians (even if you were able to do so perfectly), what you are left with is indigenous Northeastern Africans, the direct descendants of people who left Africa tens ofShow More Summary

More Y-chromosome super-fathers

The time estimates are based on a mutation rate of 1x10-9 mutations/bp/year which is ~1/3 higher than mutation rate of Karmin et al. So the values on the table may be a little lower.There may be additional founders with recent time depths...Show More Summary

Neandertal in the (immediate) family tree

Early European may have had Neanderthal great-great-grandparent One of Europe’s earliest known humans had a close Neanderthal ancestor: perhaps as close as a great-great-grandparent. The finding, announced on 8 May at the Biology ofShow More Summary

2,500-year old Etruscans

From a Biology of Genomes poster (pdf) on "Assessment of Whole-Genome capture methodologies on single- and double-stranded ancient DNA libraries from Caribbean and European archaeological human remains" by Ávila-Arcos et al.All that can be said based on this is that they seem broadly southern European and not particularly Tuscan.

Ancient mtDNA from Neolithic France

An intense debate concerning the nature and mode of Neolithic transition in Europe has long received much attention. Show More Summary

Facial reconstruction of Lord of Moken

I wonder when we will start seeing facial reconstructions that make use of ancient DNA. Ancient DNA isn't very good for reconstructing facial features, but it should be quite good at reconstructing pigmentation. Facial reconstruction...Show More Summary
