Human impacts on large mammals went well beyond triggering late Quaternary mass extinctions. A new paper by Brook et al. showing that biogeographic patterns were erased by the spread of domesticated species:

A related paper is in press. Stay tuned.

The genomics of discrete polymorphisms maintained by disruptive selection

Disruptive selection can lead to the evolution of discrete morphs. We show that particular genetic architectures, in terms of dominance, epistasis, and linkage, are likely to evolve to produce discret...

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

Why do speciation rates vary across the tree of life?
Some of the best yet most underappreciated places for this investigation are natural hybrid zones.
This preprint takes you to the hybrid zones in the origin of species to find a clue. 👉 shorturl.at/N7FXE
