Our paper on the evolution of MUC19 in humans, Neanderthals, and Denisovans is finally out today in Science! This has been a six-year effort by 13 authors to weave together 3 separate but related evolutionary stories around this one gene (more on thread 🧵).

The MUC19 gene: An evolutionary history of recurrent introgression and natural selection
We study the gene MUC19, for which some modern humans carry a Denisovan-like haplotype. MUC19 is a mucin, a glycoprotein that forms gels with various biological functions. We find diagnostic variants ...
