source-sink dynamics
Climate models, Neandertals, and Denisovans
A new paper on biogeography of Neandertals and Denisovans raises ideas about the interactions of these groups.
Should we be surprised if Neandertals, Denisovans, and modern humans didn’t form stable hybrid zones?
A geneticist asks why we don't see more persisting hybrid populations, and I find an answer in the theory of population source-sink dynamics.
Did Neandertals evolve in a population sink?
The dynamics of adaptation in shrinking populations may help understand how many ancient populations evolved.
