Reposted by @cfraisserios.bsky.socialCamille Roux @crouxevo.bsky.social · 12/09/2025Hybridization 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 3207120

Reposted by @cfraisserios.bsky.socialNicolas Galtier @nicolasgaltier.bsky.social · 11/01/2025In 2010 (SMBE Lyon) I gave a talk about the impact of GC-biased gene conversion (gBGC) on functional sequence evolution. I argued that, because gBGC promotes G and C alleles irrespective of their fitness effect, it should generate some genetic load. 1/5 23121
