I still love the theory a Year 6 child proposed to me that David Attenborough is actually God and he got fed up with people not noticing the amazing things he'd created, so he made documentaries to show off.

Es pot tenir una societat d’individus amb sentit crític sense coneixements científics? La ciència, la filosofia i, en particular, la teoria de l’evolució són puntals necessaris que s’han de reforçar, no debilitar, en el sistema educatiu.

This project (with Stacy Rosenbaum and Nick Grebe) began in the dark days of Covid, and is finally ready to share. We've built a living database of primate paternity data (52 species, 3000 paternities) and completed first wave of analyses of paternity distribution.
