Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Breaking genetics news‼️🌱🌽 A natural DNA trick triples recombination in maize. What we first saw in Arabidopsis (@hendersi lab) a decade ago is now confirmed in crops—opening new doors for plant breeding. Published today in Nature Plants! More details 👉 www.nature.com/articles/s41...

super excited to share this big project with @daeaton.bsky.social out now in Systematic Biology! We derived distributions for -- given an arbitrary species tree model -- how far you have to move along a genome before observing a change in the underlying genealogy: doi.org/10.1093/sysb...

How many chromosomes can an animal have? In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact. www.cell.com/current-biol...

New Preprint! This one led by Sam Gibbon, an outstanding undergrad I've worked with for the past year. We take a look at whether segregation patterns in tetraploids (disomic v polysomic) affects mut-sel dynamics. We found some surprising results, and some subtleties: www.biorxiv.org/content/10.1...

New Paper! In 2019, my first dissertation chapter revealed complicated polyploidies in the cotton family (Malvaceae) but we lacked the tools and genomes to truly understand it. Now with better genomes and improved methods, it's much more complicated than we thought. www.nature.com/articles/s41...

Notice Of Award for the renewal of our department's NIH T32 graduate student training grant arrived yesterday. Five years of funding for 8 students a year is a huge relief in this climate.
