Cold comfort: Fat-rich diets and adaptation among indigenous Siberian populations

Recently, scientists have been exploring the genetic signatures of adaptation in several indigenous cold-adapted human populations. Now, a new study has identified new signals of adaptation across multiple genes and exploring a rich demographic history. By performing extensive analyses on DNA sequencing data for two North-Central Siberian populations, the Nganasan (nomadic hunters) and Yakut (herders), they have been able to infer the most comprehensive demographic and adaptive history. …read more
