A groundbreaking paleogenomic study published in Nature Genetics Reviews has analyzed the remains of 42 individuals from the Funnelbeaker culture in Southern Scandinavia. The research identifies a significant genetic shift occurring approximately 5,200 years ago, marking the earliest known human adaptation to low-UV environments through the selection of specific alleles involved in Vitamin D metabolism and skin pigmentation.
The study reveals that as these early farming communities transitioned from a hunter-gatherer diet rich in Vitamin D to a cereal-based Neolithic diet, their genomes underwent rapid selection to maximize synthesis from sunlight. This evolutionary breakthrough provides a precise timeline for the emergence of modern Northern European phenotypic traits, linked directly to the dietary pressures of early agriculture.
