Our new paper is out in @nature.com! By exploring the rich genetic diversity of Indigenous peoples across America, we show how large-scale genomic data reveal far more complex evolutionary history, shaped by multiple dispersals, long-term regional continuity, and adaptation to diverse environments.

A genetic study of 125 Sudanese people explores how a gene variant responsible for malaria resistance emerged as Copts, a Sudanese minority group originally from Egypt, intermixed with local Nilo-Saharan individuals 1,000 to 1,500 years ago. In PNAS: ow.ly/o6C950XY3H0

Hominin fossils discovered in Morocco, which have been dated to about 773,000 years ago, may be close ancestors of modern humans. The findings, published in Nature, provide insights into African populations before the earliest known Homo sapiens.🧪

Beautiful study of the population history of Sudan, including a striking signature of adaptive admixture in the Duffy-null blood group gene, potentially as a mechanism of local adaptation to Plasmodium. Congratulations @lvilavalls.bsky.social, what a great regal de reis!
