New paper out! A nice collaboration.
We explore how olfactory brain structures and receptors evolved across this remarkable group, Heliconiini butterflies.

Evolution of the olfactory system during the radiation of Heliconiini butterflies

Abstract. Sensory system evolution plays a crucial role in shaping species’ interactions with their environment, yet the extent to which olfactory system d

A GPCR signaling pathway in insect odor detection

Odor detection differs fundamentally in vertebrates, which use G protein-coupled receptors (GPCRs), and insects, which employ ion channels. Here, we report the first evidence for a GPCR defining tunin...

Figure 1A from the paper shows the distribution of black-headed (western) and rose-breasted grosbeaks (eastern) throughout North America. Small illustrations of males of each species are shown. Black-headed has a rusty orange breast and black head, while rose-breasted has a small reddish bib with a bright white belly. There is an inset map of South Dakota showing the transect across the hybrid zone

Our paper on rodent thumbnails is out! Big team effort, powered by museum collections. Turns out, nails can reveal a lot about rodent evolution. Shoutout to Dr. Gordon Shepherd for the wild idea to study rodents thumbs!

Science Magazine @science.org · Sep 4

New findings in Science suggest that rodents owe much of their evolutionary success to their thumb-nail (the first digit, D1), an adaptation that gave them dexterous hands for cracking seeds and nuts.

This red squirrel’s hands display tiny nail-bearing thumbs, alongside large claw-bearing digits.
