Tradeoffs Between Fertility and Predation in the Evolution of Mammalian Social System

Explore the complex interplay between fertility, predation, and social evolution in mammals through this insightful lecture. Delve into topics such as group size dynamics, the central problem of sociality, and the negative impact of co-resident females on fertility. Examine the cognitive demands of bonding, socio-cognitive grades in primates, and the endocrinological aspects of social systems. Investigate predation rates, inhibition as a social requirement, and baboon group size distribution. Analyze fertility patterns in baboons and discuss the two main routes to sociality. Participate in a Q&A session on Slack to further engage with the material and deepen your understanding of mammalian social system evolution.
