Genes the Secret to Surviving A Siberian Winter

摘要

Frigid Siberia has been home to humans for tens of thousands of years, including Homo sapiens and Neandertals. A study of today's Siberian peoples, presented last month at the Unravelling Human Origins meeting in Cambridge, U.K., finds that their genes may help them adapt to cold conditions. Alexia Cardona, a graduate student at the University of Cambridge, and her colleagues analyzed 200 DNA samples from 10 indigenous Siberian populations and looked for genes that might correlate with cold adaptation.
