Microagressions, debunked

A warning against taking politically-inspired gobbledygook (whose only benefit is to bureaucrats and as a means of virtue signalling by do-gooders) seriously. Perspectives on Psychological Science Vol 12, Issue 1, 2017 Microaggressions Strong Claims, Inadequate Evidence Scott O. Show More Summary

Dysgenic trend in educational attainment in Iceland

This is a very important study which (if replicated in other countries, with more complex demography, less complete genealogy, but much larger sample sizes) bodes ill for the future. It should also prompt studies of the evolution of cognitive ability at longer time scales (beyond traditional genealogy). Show More Summary

Happy New Year 2017

Last year I wished for ancient East Asian DNA and I didn't get my wish. So, I repeat my wish for this year as well.

Facial reconstruction of Griffin warrior

The face of Bronze Age fighter revealed: Scientists reconstruct face of the 'Griffin Warrior' who was part of an elite group 3,500 years ago

China's Great Flood and the rise of the Xia dynasty

From a related story: Massive flood may have led to China's earliest empire:Many cultures trace their origins to the hazy horizon where history meets legend. In China's case, that blurry line occurs sometime between 2200 B.C.E. and 2000...Show More Summary

Educational achievement predicted by DNA

Predicting 9% of educational achievement from DNA is quite good. The authors used genotype arrays, so there's obvious room for growth in rare variation that is not covered by such arrays.I wonder when the public and policymakers will...Show More Summary

Y-chromosome haplogroup N phylogeny resolved

AJHG Volume 99, Issue 1, p163–173, 7 July 2016 Human Y Chromosome Haplogroup N: A Non-trivial Time-Resolved Phylogeography that Cuts across Language Families Anne-Mai Ilumäe et al. The paternal haplogroup (hg) N is distributed from southeast Asia to eastern Europe. Show More Summary

37,000 year old skull from Malaysia related to indigenous people of Borneo

Front. Ecol. Evol., 27 June 2016 | http://dx.doi.org/10.3389/fevo.2016.00075 Deep Skull from Niah Cave and the Pleistocene Peopling of Southeast Asia Darren Curnoe et al. The Deep Skull from Niah Cave in Sarawak (Malaysia) is the oldest anatomically modern human recovered from island Southeast Asia. Show More Summary

Population history with physically phased genomes

bioRxiv doi: http://dx.doi.org/10.1101/008367 Modeling human population separation history using physically phased genomes Shiya Song, Elzbieta Sliwerska, Sarah Emery, Jeffrey M Kidd Phased haplotype sequences are a key component inShow More Summary

Panorama of African admixture

I remember how in the early days of online discussions of anthropology a constant topic of contention was whether African variation was the result of admixture, some of it within Africa, some of it from Caucasoids, or whether it wasShow More Summary

700 thousand year old ancestors of H. floresiensis

Nature 534, 245–248 (09 June 2016) doi:10.1038/nature17999 Homo floresiensis-like fossils from the early Middle Pleistocene of Flores Gerrit D. van den Bergh, Yousuke Kaifu, Iwan Kurniawan, Reiko T. Kono, Adam Brumm, Erick Setiyabudi, Fachroel Aziz & Michael J. Show More Summary

Ancient DNA and human history

A very useful review of the field c. mid-2016. The only major addition would be the study on Upper Paleolithic Europeans that appeared recently.The lack of East Asian DNA validates my New Year's wish for some. Hopefully my wish willShow More Summary

Neolithic Aegean genomes

I had covered this paper when it went on the bioRxiv, but the final version has been published in PNAS in open access. PNAS doi: 10.1073/pnas.1523951113Early farmers from across Europe directly descended from Neolithic AegeansZuzanaShow More Summary

Mungo Man DNA revisited + first ancient mtDNA from Australia

The authors find that previously published mtDNA from earliest Australians was contamination, and one S2 mtDNA haplogroup in an undated sample of likely Holocene origin.PNAS doi: 10.1073/pnas.1521066113Ancient mtDNA sequences from the First Australians revisited Tim H. Show More Summary

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. Show More Summary

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
