May 2026 in “Zenodo (CERN European Organization for Nuclear Research)” 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.
May 2026 in “Zenodo (CERN European Organization for Nuclear Research)” 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.

June 2008 in “Human mutation” This study found that a genetic variant in the EDAR gene leads to typical East Asian hair characteristics by increasing signaling output, as shown in transgenic mice experiments.
