Evolutionary psychologists have long believed that men prefer physical traits in women which are cues to high potential fertility. A new review concludes: “current evidence base is too weak to support the claim that women’s feminine morphological traits are associated with reproductive potential”

My first paper, out in PsychReview!!
Along with @orbenamy.bsky.social, Nik & @jaeggiadrian.bsky.social, @realadamhunt.bsky.social & I revisit an old theoretical question using concepts from evo psychiatry and anthro:
Why do mixed associations exist b/w social media & mental health?

Just got this book by one of my favourite anthropologists (and people) in the mail - if it's only half as good as the gushing advanced praise, this'll be an instant classic! Also, brilliant title, immediately putting to bed the notion that long lifespan is a new thing; we've evolved to live to ~70

Jordan Martin @jsmartin.bsky.social used a sophisticated evo quant gen approach to show that neighboring women enhance each other's fertility among the Tsimane, which accelerates adaptive evolution. This 'social drive' helps explain the rapid pace of human evolution. See thread and paper for more!
I'm very excited to share the central paper from my PhD out now in Science Advances. We investigated how social effects among neighbors shape the evolution of reproductive cooperation and the pace of adaptive population growth among the Indigenous Tsimane of Bolivia.
