Scanning mussel morphology #MusselsAreCool. The attempts are not yet conclusive, but it's cool.

Sujet de stage M2 sur la "dock mussel", cet écotype de moules hybrides qui habite dans les ports. L'objectif est de tester si la dock mussel s’est adaptée grâce à sa variance génétique d’admixture ou si l’admixture n’est que le corolaire du contact secondaire entre les deux espèces parentales.

If you’ve heard about our study on ants producing two different species but are still confused about how it works (and don’t have time to read the paper), this 10-minute video made by @bengthomas.bsky.social is very informative:

The first Aguillon Lab paper is officially out in early view at Evolution!! Led by postdoc @devonderaad.bsky.social, we’ve explored the hybrid zone between black-headed and rose-breasted grosbeaks in the Great Plains. #ornithology #hybridization #speciation #evolution doi.org/10.1093/evol...

Figure 1A from the paper shows the distribution of black-headed (western) and rose-breasted grosbeaks (eastern) throughout North America. Small illustrations of males of each species are shown. Black-headed has a rusty orange breast and black head, while rose-breasted has a small reddish bib with a bright white belly. There is an inset map of South Dakota showing the transect across the hybrid zone

Curious to hear thoughts from #popgen, #humangenetics, #genomics folks on recent paper:

www.pnas.org/doi/10.1073/...

"Directed mutation" in specific human pop'ns seems unlikely to me. DM didn't stand up as proposed in bacteria, but there are hot spots shaped by past selection. Plausible here?

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

This is the best explanation of the weird new ant paper.

EssayWells @essaywells.bsky.social · Sep 4

The paper has helpful diagrams and it's WILD. They clone the other species so they can produce sterile hybrid workers. It's like if a horse could occasionally give birth to a donkey deliberately so they can make mules to serve them while they sit on their... horse throne... as horse queens do.
