There seems to be a deep and ancient connection between the populations of Southeast and South Asia, most evident in the substrate of the Cambodians. In First Farmers the author relays an early report about a farming community in northern Vietnam where morphological and ancient DNA evidence both pointed to a stabilized coexistence between a...

Greg Cochran has a few posts up on the phylogeography of SLC24A5. A quick refresher: this gene has been under very strong selection across Western Eurasia, and seems to correlate with lighter skin. One of Cochran's points is that though it is fixed (100%) for the new variant in Europe, it persists at very high... Read More
The Pith: Afro-Indians are mostly African, with a substantial Indian minority ancestry. The latter is disproportionately female mediated. It also seems that that ancestry is more northwest Indian, and that natural selection has been operating upon them outside of the African environment. Along the western coast of South Asia, from Makran in southwest Pakistan, down... Read More
As I've been harping on and on for the past few years that the patterns of contemporary genetic variation are probably only weakly tied to past patterns of genetic variation (though Henry Harpending warned me about this as far back as 2004). A major reason that scholars operated under this presupposition is the axiom that... Read More
The Pith: Honorable intent and punctilious adherence to proper form and method does not guarantee a set of results which flesh out a genuine phenomenon. Much of science is tragic. Most of the time I point to and review papers on this weblog which excite me. But in the interests of "balance" and dampening the... Read More
Zack Ajmal has been taking his Reference 3 data set for a stroll over at the Harappa Ancestry Project. Or, more accurately, he's been driving his computer to crunch up ADMIXTURE results ascending up a later of K's. Because it is the Harappa Ancestry Project Zack's populations are overloaded a touch on South Asians. He... Read More
Whenever Zack Ajmal posts a new update to the Harappa Ancestry Project he appends some data to his ethnic database. This sends me to Wikipedia, because how many people are supposed to know what a "Muslim Rawther" means? Well, if you are a Muslim Rawther, and perhaps from Southern India, you would. But South Asian... Read More
School girls in Hunza, Pakistan A few days ago I observed that pseudonymous blogger Dienekes Pontikos seemed intent on throwing as much data and interpretation into the public domain via his Dodecad Ancestry Project as possible. What are the long term implications of this? I know that Dienekes has been cited in the academic literature,... Read More
I mentioned a few days ago that a friend was trying to get together some data to analyze the genetic variation of South Asians. By a strange coincidence Dienekes just published a more detailed analysis of South Asians...and uncovered something very interesting, though not that surprising. Some technical preliminaries: In addition to the various online... Read More
The past ten years has obviously been very active in the area of human genomics, but in the domain of South Asian genetic relationships in a world wide context it has seen veritable revolutions and counter-revolutions. The final outlines are still to be determined. In the mid-1990s the conventional wisdom was that South Asians were... Read More
