The Evolutionary Psychology Behind Sibling Rivalry, Mating Strategies, and Human Behavior | Catherine Salmon

Evolutionary psychologist Catherine Salmon delves into the evolutionary explanations behind sibling rivalry, parental investment, optimal spacing and number of offspring, and the challenges of increasing fertility rates in Western countries. She explains the influence of evolutionary pressures on modern mating strategies, dating dynamics, and differences in sibling roles.

Additionally, we discuss eating disorders among teenage girls, the psychological mechanisms driving these behaviors, and the impacts of modern social and environmental factors.

The conversation extends to the role of birth order, the stress from competition, the implications of psychopathy and sociopathy, and factors driving certain sexual behaviours and preferences. This comprehensive discussion sheds light on diverse aspects of human behaviour through the lens of evolutionary psychology.
