New preprint 🚨 Traditionally, the Hadza lived as mobile hunter-gatherers, moving camps several times per year. Today this is changing - but why? We show that subsistence transition offers multiple pathways to food security. Families who move less are *substantially* more food secure.

Moving On From Movement: Sedentism Provides a Key Pathway to Food Security for Hadza Hunter-Gatherers
Extensive discussion attends to the disadvantages of shifting from mobile hunter-gatherer subsistence  to sedentary living. Fewer studies have investigated

New research from a large collaborative team exploring what fathers think fathering is. Gendered expectations were clear, but so was some flexibility around these expectations, as well as variability in the fathering role associated with child's sex and age

I've changed my mind about the origins of essentialist intuitions quite a bit over the years, and it was great to have Wolfgang Wagner renew my attention to the puzzle. So many clever contributors have refined my beliefs about the phenomena and changed my mind about what we know.

Thanks to the Baylor media office for doing a nice write-up of my recent PNAS Nexus article with @kris-smith.bsky.social. Of course, we also saw tremendous generosity in these economic experiments (!), but "life-like" sharing patterns only occurred when people took from peers in surplus.

If one man marries two women, another man must go unmarried, right? No. Demography matters. If sex ratios are skewed towards women, then polygyny can exist alongside universal marriage for men (who want to marry women). If only more people understood demography 😊
