Picture of 6 postgrad students sat at a table in a lab studying bones. Text says: The UCL Palaeoanthropology and Palaeolithic (PaPa) MSc programme is an established, pioneering course in human origins delivered by a world-leading university. It will bring you a deep and expert understanding of the scientific record of human evolution which powerfully combines opportunities for the study of palaeolithic archaeology, palaeoanthropology and wider scientific approaches to the early human story.

Interested studying human evolution at @ucl.ac.uk with a dedicated MSc in palaeolithic archaeology, palaeoanthropology, Ice Age fauna, isotopes, aDNA, ancient environments & more?
Get in touch for a chat or even a tour of the department with me.

Association between lactase persistence and height in the past (indicating people with the persistence allele were better nourished by drinking milk than those without it) provides a potential explanation for why it was under strong selection.

This workshop will examine how fundamental evolutionary forces intersect with social structures governing reproduction and population formation to influence the distribution of genetic variation and how these have significant implications for how we conceptualize race and ancestry today.

But perhaps most critically, itโ€™s (imo) irresponsible to attribute this to *science* as a whole; suggesting itโ€™s a monolith when things like the image duplication retractions are pretty limited to a unique corner of science under sleuth spotlights.
