Long abstractDemographic study of eastern Hadza hunter-gatherers between 1985 and 2000 showed a stable population with relatively normal parameters and a quite high rate of increase. Aspects discussed here are: population models and small remote populations; environmental keys to evolutionary demography of sub-Saharan savanna hunter-gatherers; grandmothers and longevity; men as helpers; whether economic and reproductive interests influence which norms invade, spread, and endure.

After a D.Phil with Niko Tinbergen on aggressive displays of Parus major I switched to trying to apply ethologists' perspectives in direct studies of humans, e.g. edited volume Ethological Studies of Child Behaviour (CUP 1972). Collaboration with MJ Konner on San children in Botswana, and field work on Hadza hunter-gatherers in Tanzania with Kristen Hawkes and James O'Connell led to many publications on Hadza behavior and ecology, including my 2016 book breathlessly summarized in this volume. My UCLA graduate student Frank Marlow wrote The Hadza Hunter Gatherers of Tanzania (U of California Press 2010) and supported several successful students in the field.
