Rapid adaptive increase of amylase gene copy number in Indigenous Andeans - Nature Communications The salivary amylase gene exhibits copy-number variation linked to dietary shifts. Here, the authors describe an adaptive expansion of the amylase gene in Indigenous Andean populations coinciding with... https://doi.org/10.1038/s41467-026-71450-8
