Abigail Bigham comments in the LA Times on a study a study investigating genetic relations of modern Tibetans to an extinct people known as Denisovans:

Abigail Bigham, an anthropologist at the University of Michigan who was not involved in the study, said now the search for Denisovan DNA should extend to other groups not represented in the Human Genome Diversity Panel.

“When they looked in Han Chinese, they saw it in only two individuals,” Bigham said. “But other populations in Central Asia or East Asia — there are 49 other ethnic minorities in China that have different genetic backgrounds — would have been interesting to look at as well.”
