Lec 34 - Mating Systems and Parental Care
"Lec 34 - Mating Systems and Parental Care" Principles of Evolution, Ecology and Behavior (EEB 122) Mating systems and parental care vary tremendously from species to species. Every species differs in how it protects its young from predators and provides its young with food, if it does so at all. The physical environment as well as behavioral dynamics in intraspecies relationships all influence parental care. Often the mating system, which sex is dominant in mating, and whether fertilization is external or internal will determine much of the process of parental care. 00:00 - Chapter 1.
