Those east Asians are carrying the same cold adapted genes from the same people the Northern Europeans got them from. The Denisovans and Neanderthal have a common ancestor. https://evolution.berkeley.edu/wp-content/uploads/2020/08/evo-news-denisovans.jpg https://evolution.berkeley.edu/wp-content/uploads/2020/08/ev... The ice age you’re talking about and what I’m talking about are different. The age I’m talking about is the one that caused that split. And it happened 400,000 years ago. https://cdn.serc.carleton.edu/images/eslabs/cryosphere/timeline_ice_ages_456.webp https://cdn.serc.carleton.edu/images/eslabs/cryosphere/timel... These are extremely ancient cold adaptive genes. From the study: “ Given the essential role of the mitochondria in skeletal muscle thermogenesis, we propose that the derived G allele, which we have shown provides better protection to the mitochondria, may have been positively selected to facilitate adaptation to cold while providing higher susceptibility to neuropsychiatric traits. This is a plausible scenario for a case of archaic adaptive introgression, as Denisovans and Neanderthals were probably already well adapted to the local environmental conditions modern humans encountered when expanding across Eurasia.” I admit to my over generalization Only because it can get too complicated explaining it all on HN.
