These sources explore human biological variation and adaptation to different environments, particularly focusing on Asian populations and their genetic and physiological responses. One source discusses ancient genetic mutations in East Asians that led to traits like thicker hair and more sweat glands, potentially as an adaptation to climate. Another examines differences in heat tolerance and cognitive performance between tropical and temperate Asian groups. The final, extensive source presents a dissertation on genetic and morphological evidence for local climate adaptation in the Americas, using Mayan and Quechua populations as case studies to investigate adaptations to hot/humid and cold/high-altitude conditions, including analyses of facial structure and genes related to thermoregulation and water balance.
