A deep dive into the evolutionary, anthropological, and biological roots of human sexuality
Pros
- Science-backed validation for non-monogamous relationship structures
- Accessible, witty writing that sparks meaningful conversations with partners and metamours

Cons
- Not technically about polyamory, focuses more on evolutionary biology than consentual or ethical relationship practices
The science behind non-monogamy
Drawing on research from primatology, anthropology, and human biology, Sex at Dawn challenges the long-held narrative that humans are naturally monogamous. Instead, it makes a compelling case that our ancestors thrived in communities built on shared resources, shared child-rearing, and yes — shared intimacy.
