super cool that it was decoded by amateur who lined up parturition dates of animals depicted in cave paintings.
BBC article on decryption of possible early dates/writing in cave painting. Seems super neat story, although I'm not able to judge how strong evidence is.

@caterpillar_coevolution @michaelarichter I’m confident that more PromethION reads will do the trick! But HiFi would be welcome too ;)

Interesting for relation between #evodevo and #NaturalSelection:
"These results demonstrate that natural selection can rapidly reshape developmental gene expression on a broad scale when selective regimes abruptly change. More broadly, even highly conserved dGRNs and patterning mechanisms in the early embryo remain evolvable under appropriate ecological circumstances."

🦀Big #CRUSTMAS news!🦀
New preprint on a molecular #phylogeny of true #crabs. We find crabs moved to non-marine environments 5-15x over 100+ myr!
This culminates 20 years(!) of effort from an international team! 1/5

Happy to share our last preprint:
Random genetic drift sets an upper limit on mRNA splicing accuracy in metazoans

All comments are welcome!
After 7 years of work by >100 people, we're finally getting close to releasing grambank: a global database of language structures. Check out the preprint that reveals the main dimensions of difference between languages world-wide, and quantifies what we're going to lose.

I'm very happy to share with you a preprint of our paper about language diversity through the eyes of #Grambank. I'm grateful to all of our coders …

😊 📢🎶🕸️🕷️ New preprint!
Multiple paths towards repeated phenotypic #evolution in the spiny-leg #adaptive #radiation (Tetragnatha; Hawaii)
Tetragnatha, similar to the Anolis #adaptive #radiation(s), are ' organized ' into #ecomorphs (habitat):
Green (leaf-habitat)
Maroon (mosses)
Small brown (twigs)
Large brown (tree bark)
Thread, 1/n
But I digress. They didn't find tga1. Gotta be a hard sweep. Heck, even popgen evaluation of Sanger sequence data was consistent with the idea (pictured).
So why is this even a question? Where does the current work come in?
It started with resequencing data. Our genome scans found lots of evidence of selection during domestication, but 100s of loci showed stronger signals than tga1, which is weird for what should be a hard sweep at THE domestication gene!(https://www.nature.com/articles/ng.2309).
