Genetic variants may keep Siberians warm
People in frigid cold evolved changes in fat metabolism, shivering

BOSTON— Siberians may use genes to stay warm, a new study shows.
As part of an effort to catalog genetic diversity in Siberia, Alexia Cardona of the University of Cambridge and collaborators sampled DNA from 200 Siberians representing 10 native groups. The team looked for genes that have more changes in Siberians than would be expected by chance — a sign that the genes evolved rapidly in the 24,000 years since people settled the frigid land. Rapid changes suggest that a gene is important for a...
