Don’t ask “When is it coevolution?” — ask “How is it coevolution?”
Ask me to pick a single word that describes what I study, and I’ll typically say “coevolution.” This is probably true of most evolutionary biologists who study interactions between species — plants and pollinators, hosts and symbionts, predators and prey, et … Continue reading

It’s now two weeks since I resumed in-person teaching, and so far, so good. It’s shockingly refreshing to actually interact with students directly, even with everyone masked, and to be able to just improvise with a specimen picked up on … Continue reading

It’s been an eventual two weeks in evolutionary biology. Meanwhile, I’ve somehow kept a lab-field course on track with minimal in person engagement, planned a bit for actual fieldwork in a couple weeks from now, and started wrangling a couple … Continue reading

The period between semesters is supposed to be quiet. I’ve been mentally dumping things to do into this one — paper revisions, reviewing service, analysis of long-awaited new data, a first draft of a new grant, writing my (eek) application … Continue reading

An enduring evolutionary mystery – the consequences of sex are shaped by more than sex itself
Rather shockingly, sexual reproduction remains an enigma – despite over a century of study. Theory has identified the costs and benefits of sex, illustrating why almost all* eukaryotes go to the trouble, at least occasionally. * Even supposedly obligate asexuals … Continue reading
