The dataset on India combines three different anthropological studies, one on the north-west, one on the north-east and one on the Andaman and Nicobar Islands in the south-east. The dataset covers two earlier studies, which mostly represent birth decades of the 1850s to the 1900s, and then a larger dataset on the early 20th century. Social selectivity is not an issue as these are anthropological measurements, but this dataset is not regionally representative for all of India. There has been some debate about whether early anthropologists measured very “typical” physical characteristics of the ethnic groups which they studied, implying selectivity. This can be counterchecked by comparing the early samples with the migration evidence provided by Brennan et al. (1995) and other publication by this team of authors, which has not yet been made publicly available at an individual level.
