A fascinating paper, and one worth reading as we enter a period likely to see accelerated spread of malaria back into areas from which it had been eradicated.

I am so happy to share our #newpaper on how human #distribution in #Africa was shaped by #malaria for tens of thousands of years. A wonderful work led by @margheritac17.bsky.social @elliescerri.bsky.social and @eegcam.bsky.social. I loved contributing! #prehistory #humanevolution #disease 1/2

🦟Infectious disease has shaped the deep history of our species, as new research co-authored by members of our Evolutionary Ecology Group reveals. @eegcam.bsky.social @mikleonardi.bsky.social @ceciliapad.bsky.social www.science.org/doi/10.1126/...

Malaria was fundamental in shaping the course of human evolution, @camzoology.bsky.social researchers have found. Between 74,000 and 5,000 years ago, early humans in Africa avoided high-risk malaria areas, shaping the population structure seen today. Read more 👉 https://bit.ly/4tUdOxe

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.

Many living people carry fragments of Neanderthal DNA, remnants of ancient interbreeding events, with uneven distribution across chromosomes. New work by @sarahtishkoff.bsky.social lab suggests patterns are most consistent with Neanderthal contribution to human populations being highly male biased.🧪

Interbreeding between Neanderthals and modern humans was strongly sex biased

Sex biases in admixture and other demographic processes are recurrent features throughout human evolution. For admixture between Neanderthals and anatomically modern humans (AMHs), sex bias has been p...
