In this study, researchers propose that the EDAR V370A allele's positive selection in East Asian populations may be linked to stable aquatic resources from Late Pleistocene ecosystems in northern China, suggesting a "nutritional niche construction" framework where these resources offset the allele's metabolic costs.

This study presents a hypothesis that the EDAR V370A allele was positively selected in East Asian populations due to the stable aquatic resources in Late Pleistocene northern China, which may have offset the allele's metabolic costs and provided a selective advantage.

This research found that variations in the KRTAP gene family are likely responsible for the diverse hair phenotypes seen among mammals, influenced by gene repertoire differences, expression, and evolutionary factors.

This study found that Florida manatees have unique types of specialized nerve endings in their vibrissae, which assist in their sensory and manipulative functions in aquatic environments.

This study found that cetaceans have adapted their fibroblast growth factors to assist in low bone density, hypoxia tolerance, and the development of rigid flippers, reflecting significant evolutionary changes for aquatic life.
