British Celts have more steppe ancestry than British English

An interesting tidbit in a preprint about blood pressure genes: We consistently obtained significantly positive f4 statistics, implying that both the modern Celtic samples and the ancient Saxon samples have more Steppe ancestry than the modern Anglo-Saxon samples from southern and eastern England.

The great migration of African Americans

PLoS Genet 12(5): e1006059. doi:10.1371/journal.pgen.1006059 The Great Migration and African-American Genomic Diversity Soheil Baharian et al. We present a comprehensive assessment of genomic diversity in the African-American population...Show More Summary

35,000 year old mtDNA haplogroup U6 from Romania

I wouldn't be very surprised if many of the markers supposedly signifying recent gene flow Africa and Eurasia were actually quite old in Eurasia. The trouble is that reports of such gene flow were often based on simply observing that...Show More Summary

Luwians vs. Hittites and Mycenaeans vs. Luwians

A rather imaginative reconstruction of the events surrounding the Sea Peoples and the ending of the end of the Bronze Age.

74 loci associated with educational attainment

Other than the claim in the abstract that educational attainment is "mostly environmentally determined" (), this seems like a very useful study, as it identifies 74 loci associated with educational attainment and explores their interesting biology. Show More Summary

Natural selection in Britain during the last 2,000 years

The latest ancient DNA studies from the British Isles (Schiffels et al and Martiniano et al. and Cassidy et al.) support continuity over the last 2,000 years. Sure, there were continued migrations like the arrival of the Anglo-Saxons,...Show More Summary

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.

Jewish and Indian ancestry in the Bene Israel

PLoS ONE 11(3): e0152056. doi:10.1371/journal.pone.0152056 The Genetics of Bene Israel from India Reveals Both Substantial Jewish and Indian Ancestry Yedael Y. Waldman, Arjun Biddanda, Natalie R. Davidson, Paul Billing-Ross, Maya Dubrovsky, Christopher L. Show More Summary

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

Middle (not Upper) Paleolithic hobbits

Nature (2016) doi:10.1038/nature17179 Revised stratigraphy and chronology for Homo floresiensis at Liang Bua in Indonesia Thomas Sutikna, Matthew W. Tocheri, Michael J. Morwood, E. Wahyu Saptomo, Jatmiko, Rokus Due Awe, Sri Wasisto, Kira E. 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

Adaptation in the light of ancient genomes
