Distinguishing those architectures can reveal distinct mechanisms generating—and potentially constraining—trait–trait relationships. https://academic.oup.com/mbe/advance-article/doi/10.1093/molbev/msag215/8767967?utm_source=bluesky27 Aug 2026 21:16 +0000at://did:plc:6ut7jprdbjpi2kkptrhjdmvs/app.bsky.feed.post/3mu3rgw26jk2ghttps://bsky.app/profile/haorancai.bsky.social/post/3mp5c6eensk2vNew paper out @pnas.org: We explore why fly wings evolve along "lines of least resistance" and reconcile the "rate paradox" between population variation and divergence. Check out how a low dimensional model of selection on size explains it all: https://www.pnas.org/doi/full/10.1073/pnas.261294012325 Jun 2026 20:42 +0000at://did:plc:6ut7jprdbjpi2kkptrhjdmvs/app.bsky.feed.post/3mp5c6eensk2vhttps://bsky.app/profile/haorancai.bsky.social/post/3mm3nmcukp22pI’m looking forward to presenting my project on the puzzles of fly wings evolution at the Evol-Mut-Circle seminar Tuesday, May 19th at 11:00 AM EDT/3:00 PM UTC https://molevol.org/2025/12/08/evol-mut-circle/ DM me for the Zoom info, or reach out to Arlin Stoltzfus (evolarlin@gmail.com) to sign up for the email list!
