Populations live in rapidly changing environments—droughts come and go, food sources change, human activities reshape habitats. For scientists, this raises a fundamental puzzle: How do populations ...

In natural populations, the mechanisms of evolution do not act in isolation. This is crucially important to conservation geneticists, who grapple with the implications of these evolutionary processes ...

The Hardy-Weinberg theorem characterizes the distributions of genotype frequencies in populations that are not evolving, and is thus the fundamental null model for population genetics. Under the ...

For decades, ever since biologists recognized the potential environmental harms from climate change, they have worried that plants will not be able to evolve fast enough to adapt to a rapidly warming ...
