Sympatric species often exhibit permeable reproductive barriers, yet many of them coexist as phenotypically distinct entities. One way to account for this apparent paradox is that selection on loci th...

Monkeyflowers reveal an overlooked role for introgression in speciation.

Opinion | Charles Darwin’s books offer lessons for how to grapple with the current state of science and its complicated future.

The science he helped pioneer consistently undermines his view that genes determine everything about us.

Postzygotic reproductive isolation is often thought to accumulate as a byproduct of neutral divergence. Yet, it frequently evolves rapidly, in line with non-neutral evolution. A major driver of intrin...

How do new species arise? This is among the most fundamental questions in evolutionary biology. The first genetic model for how reproductive barriers lead to the origin of new species was proposed nea...

Plant Evo-Devo

Recently, several new speciation genes have been identified that have contributed to our understanding of the molecular details of the evolution of hybrid dysfunction. This Progress article describes ...
