Others in Siberia

The complete mitochondrial DNA genome of an unknown hominin from southern Siberia: With the exception of Neanderthals, from which DNA sequences of numerous individuals have now been determined…the number and genetic relationships of other hominin lineages are largely unknown. Here we report a complete mitochondrial (mt) DNA sequence retrieved from a bone excavated in 2008…

The Andrew Pollack piece which I hinted at came out a few days ago: Consumers Slow to Embrace the Age of Genomics. For what it’s worth, I think this chart from Dr. Daniel MacArthur is right on: This too will pass. I believe that like the internet the knowledge and analysis of our genetic information…

The luck of the Irish

Henry Louis Gates Jr. is looking for his male Irish forebear using genetics: Well, it turns out that the men sharing that Ui Neill haplotype tended to have certain surnames. If we use those surnames, we narrow the number of possibilities in Allegany and Hampshire counties to 178 men born between 1800 and 1830 bearing…

A few weeks ago I commented on the paper about the origin of the small dog phenotype in the Middle East. Now The New York Times has an article on a newer paper, New Finding Puts Origins Of Dogs in Middle East. Here’s the conclusion: Dog domestication and human settlement occurred at the same time,…

A little bit of the Others in Us

Dienekes has reposted some of the abstracts from the meeting of the American Association of Physical Anthropologists. This one caught my eye,

Over the past week I’ve been asked via email and on message boards about about David Shenk’s new book, The Genius in All of Us: Why Everything You’ve Been Told About Genetics, Talent, and IQ Is Wrong. Since I haven’t read the book I can’t really comment, but I did finally listen to Will Wilkinson’s…

I see white people (in China)

There’s an article in The New York Times on the recent paper which extracted genetic material from remains in Xinjiang dated to 4,000 years ago. Remember that these remains exhibited male lineages which were west Eurasian, specifically R1a1, while the female lineages (mtDNA) were more heterogeneous, both eastern and western. This particular twist in history…

Two papers on Ancient DNA

The odds of knowing your cousins: 23andme Part 1: Bizarrely, Jonathan Zittrain turns out to be my cousin — which is odd because I have known him for some time and he is also very active in the online civil rights world. How we came to learn this will be the first of my postings…

Over the history of this weblog I have blogged about pigmentation a fair amount. The major reason is that that’s where the money is; unlike height, let alone intelligence, the genetic architecture and evolutionary history of pigmentation has been elucidated with relative clarity. That is, we know roughly the number and nature of the genes…
