Is the rate of protein evolution really constant through time? In our new preprint, we map lineage-specific shifts in evolutionary rates across thousands of protein families spanning the tree of life and explore how evolutionary history and protein structure shape these patterns. Check it out:

Our new study is now available on @molbioevol.bsky.social Here, we show that the loss of prfB autoregulation might be driven by compensatory evolution rather than direct adaptation of prfB expression. Sometimes, such complex traits can be an 'Evolutionary jail', constraining a species from escaping.

@sungbin.bsky.social et al. explore the evolutionary forces behind prfB autoregulation loss to illustrate how compensatory evolution can favor trait loss when the fitness benefit of losing the trait outweighs its cost. 🔗 doi.org/10.1093/molbev/msag125 #evobio #molbio

​My loyalties are split for this year's Ig-Nobel favorite. It's a dead heat between the physicist who analyzed how to stir pasta and the theorist who suggested to eat teflon to reduce calories. ​Both feel equally essential to the future of humanity. #IgNobel #Science
