- Reposted by Mike BarkerNew paper out: “allopatric” Drosophila species aren’t so allopatric after all. We show that most currently allopatric species pairs probably overlapped in the past and exchanged genes at levels similar to sympatric pairs. @evolletters.bsky.social doi.org/10.1093/evle... [1/6]
- Reposted by Mike BarkerThis is a disaster. I would not be where I am today without the constructive (and yes, sometimes frustrating) reviews my NSF proposals received as a young investigator. This feedback didn't come from the POs but rather the peer reviewers and panelists who saw how I was trying to enter the field

- Reposted by Mike BarkerFascinated to learn that we are still discovering new species at the highest rate ever. Mapping Earth's biodiversity is far from over, and while we learn more and more about it, let's protect what we do know as well as we can! www.science.org/doi/10.1126/...

- Reposted by Mike BarkerOne of the most exciting works of my career, years in the making. We used high-throughput precision genome editing to test the fitness effects of thousands of natural variants. Our findings challenge the long-held assumption that common variants are inconsequential. www.biorxiv.org/content/10.1...
