Darwin first proposed evolution as a way that species change and diverge to fill niches in their environment. This observation led to the first, rudimentary species trees, showing ancestors and descendants across genetic lineages. But this work is far from settled. As we continue to collect more and richer data sets from species, whether they be plants, bacteria, or mammals like ourselves, researchers need new and better methods for building phylogenetic trees. That’s where Tandy Warnow, from the University of Illinois Urbana-Champaign, comes in. Find our transcript here: LINK Curious to learn more?
