Summary

Story summary

The study analyzed nearly 16,000 ancient genomes from West Eurasia and identified 479 gene variants shaped by natural selection.
It contradicts prevailing views that natural selection over the past 10,000 years was rare.
It shows higher frequencies of light skin, red hair, and resistance to diseases such as HIV and leprosy.
Environmental changes, especially the shift to agriculture, shaped genetic adaptation and inform future studies of global human evolution.
