Great article on current state of ADHD research, much of it consistent w/ the evo mismatch hyp & also w/ work by @realadamhunt.bsky.social One thing I didn't know: kids who consistently take stimulant medication for ADHD are about 1 inch shorter than those who don't🧪 www.nytimes.com/2025/04/13/m...

1. I know nothing about heritability of traits, but I thought I'd take a shot at understanding this famous paper. It describes a method of estimating heritability from genetic sequences that overcomes limitations of twin studies: 🧵🧪 #BioAnth www.nature.com/articles/s41...

New paper on the obstetrical dilemma from @xliaoyi.bsky.social et al. using UK Biobank data: "Our observed genetic correlation between birth canal width & infant & adult head width provides support for the coevolution of the human brain & pelvis." 🧪 #BioAnth www.science.org/doi/10.1126/...

TIL that measles can infect and persist in the brain, and then (rarely) FIVE TO TEN YEARS LATER, kills you. There are no effective treatments. Vaccination against measles obviously prevents this 🧪 journals.plos.org/plospathogen...

When I was in grad school in the 90's the rule of thumb from twin studies was that the heritability of everything was ~50%. It turns out that twin studies are highly confounded, & after unconfounding w/ new genome-based methods (Family-GWAS), the median heritability of behavioral phenotypes is ~5% 🧪
