CIP wrote in the comments to the previous post about the 2016 Reich paper:
This is in accord with the conventional view that Europeans and Asians probably separated after leaving Africa in the Middle East. East Asians then separated from South Asians in India and Amerindians and related groups separated from East Asians much later.Guest wrote in the comments about the 2009 Reich paper:
One, the ‘Ancestral North Indians’ (ANI), is genetically close to Middle Easterners, Central Asians, and Europeans, whereas the other, the ‘Ancestral South Indians’ (ASI), is as distinct from ANI and East Asians as they are from each other. By introducing methods that can estimate ancestry without accurate ancestral populations, we show that ANI ancestry ranges from 39–71% in most Indian groups, and is higher in traditionally upper caste and Indo-European speakers. Groups with only ASI ancestry may no longer exist in mainland India. However, the indigenous Andaman Islanders are unique in being ASI-related groups without ANI ancestry.Guest wrote this in another comment:
You are confusing the ANI and Indians who currently live in the North. All Indians studied in the Reich paper (except Andamese) are mixtures of ANI and ASI, and consequently more related to each other than to outside groups like West Eurasians. The two papers are quite consistent, and David Reich is an author on both papers.
