#FunFact: Mammals indigenous to the high Tibetan plateau all have similar mutations to the same EPAS-1 “gene”. Horses, yaks, pigs, dogs, and humans all evolved convergently in a way that provides larger and more red blood cells that carry more hemoglobin than do related animals at lower elevations. (Horses did it best.) The human mutation originated in the #Denisovan populations in the Altai region of eurasia ≈80KYA.
