Oxytocin varies across the lifecourse in a sex-specific way - new paper in @pnas.org working with Tsimane communities. For women, OT looks like a sex hormone and is linked to breastfeeding and childcare. For men, probably more related to health and aging.

Have been looking forward to seeing this come out. The fundamental population problem is: what is a population?
Excited to finally have this article out with @robingnelson.blacksky.app. Although we have nominally centered populations as our unit of evolutionary analysis in biological anthropology, we have no coherent understanding of what a population is. onlinelibrary.wiley.com/doi/epdf/10....

Salivary Testosterone, Age, and Adiposity Associations Among Shuar Males in Amazonian Ecuador Challenge Assumptions of “Normal” Testosterone Patterns
