En garde! Assortative mating in hybrid swordtails
Understanding reproductive isolation is a pretty darn important part of understanding evolution. For new species to form, gene flow needs to be limited in some way. Under allopatry, limiting gene flow is straight forward; individuals never encounter each other so … Continue reading

Habitat-matching dispersal facilitates local adaptation
Migration disrupts local adaptation. At least, this is the first reaction I have when I consider these two processes. In fact, my initial thought is almost always: how strong does selection have to be to overcome gene flow? Gene flow … Continue reading

Current geography has little to say about gene flow during divergence
The terms we use to describe the geography of speciation are deceptively simple. Mention allopatry, parapatry, or sympatry, and most biologists will have a clear picture of the underlying conceptual model of range limits (and probably some strong opinions about … Continue reading

Conifer convergence
Convergent local adaptation is typically studied within a species or between closely related species. In these cases, it is perhaps not unexpected to observe parallel evolution due to common genetic variation, constraints, etc. Convergence between species is somewhat less studied, … Continue reading

The Hidden History of Kiwi Diversification
Of the millions of Earth’s species that likely remain to be described, a majority is thought to be invertebrates, plants, fungi, or microbes. Nevertheless, the pace of species description in some vertebrate groups has not slackened over the past few … Continue reading
