Still ruffling feathers after all these years: Darwin’s finches and a molecular view of adaptive radiation

One of the many lovely things about molecular ecology is its ability to shine new light on old stories. The well-known case of Darwin’s finches is a classic example of adaptive radiation. These finches demonstrate a clear instance where over time, … 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

It’s not the size that counts: teeny tiny SAR11 bacteria play a big role in our oceans

Microbes account for a huge chunk of the diversity on this planet, are essential in all sorts of biogeochemical processes, and we are still figuring out how everything is related. Teeny tiny bacterial cells are abundant both on land as … Continue reading

Visualizing the evolution of bacterial resistance

You have probably already seen this. It’s pretty amazing and beautiful and I watched it more than once (although I won’t say how many times….). If by some chance you didn’t catch this fantastic video, don’t fret, I’m here to … Continue reading

The Genomics of Rapid Adaptation

Phenology (the timing of life cycle events such as growth, breeding, or migration) is among the most sensitive organismal traits to climate and environmental change. In recent years, phenological shifts have been documented in numerous taxa, in traits such as … Continue reading

New insight into the genetic basis of industrial melanism

The evolution of coloration in peppered moths during the industrial revolution is one of the most well known examples of natural selection in action. Part of the appeal of the system is the apparent simplicity. The once-abundant light colored morph … Continue reading

New World snakes are “mimics until proven otherwise”

Henry Walter Bates spent more than a decade living in the Amazon, having the sort of adventures that inspired generations of naturalists. His most famous and lasting contributions to natural history are his foundational descriptions of mimicry among species. The type … Continue reading
