Explore the diverse world of mating systems and parental care in this 41-minute lecture from Yale University's "Principles of Evolution, Ecology and Behavior" course. Discover how species vary in protecting and providing for their young, influenced by physical environments and intraspecies behavioral dynamics. Examine the connections between mating systems, sex dominance, and fertilization methods in determining parental care processes. Learn about different types of parental investment, the relationships between mating systems and care strategies, and the social and reproductive factors influencing parental involvement. Gain insights into evolutionary biology and animal behavior through this comprehensive exploration of reproduction and offspring care across species.
