🪱 Selfish genes are everywhere and drive some of biology’s biggest innovations (CRISPR, antibody recombination, epigenetics). Yet almost no one asks the obvious question: how does a selfish gene begin? Our new manuscript uncovers how selfishness can emerge directly from the host genome.

Happy to share that my PhD project is finally published!🪱✨
Selfish genes are found across the tree of life. They can disrupt inheritance patterns and at the same time act as units for molecular innovation. Here we tried to answer one big question: how do selfish genes emerge in the first place?

Selfish X chromosomes are these bizarre things where males carrying the selfish X suffer from imploding testes. Lots to do in this space, especially in evolutionary, stress, and infection biology.

Check this out. @artermeret.bsky.social and @spo11rulz.bsky.social cleverly used protein structural information to pinpoint the action of selection and evolutionary constraints in 3D space on meiotic recombination proteins.
The main project of my postdoc with @spo11rulz.bsky.social is now available on bioRxiv! By systematically integrating structural information with molecular evolution analyses, we gained new fascinating insights into the evolution of key meiotic recombination proteins: www.biorxiv.org/content/10.1...
