🚨 The Economist has been telling you for years that polygamy causes civil war by locking men out of marriage. A new article with @rebeccasear.bsky.social and @anthrolog.bsky.social explains that the demography of marriage markets doesn't actually work that way. 🧵 www.pnas.org/doi/10.1073/...

The problem with this conversation is that people dont distinguish between "sex" and "sexual phenotype". The first, as Ed explains, is not actually a property of an individual, but rather a set of options in an evolutionary game theory setup. There are indeed only two of these sexes (in mammals)

Very disappointed that we were forced to cancel our field season and return early, following the suspension of our NSF grant as part of Trump’s attacks on UCLA. Particularly sad for our students, who spent significant time and effort to join us this year.

The great Jane Lancaster has passed away. She was a titan and very kind to me all the years I was at UNM. See a tribute from her friend and mine, Bob Hitchcock here: link.springer.com/article/10.1...

Huge congrats Cody! Excited to have you join us!
