"Lec 20 - Coevolution" Principles of Evolution, Ecology and Behavior (EEB 122) Coevolution happens at many levels, not just the level of species. Organelles such as mitochondria and chloroplasts serve as good intracellular examples. Other living things make up a crucial component of an organism's environment. Coevolution can occur in helpful ways (symbiosis) and in harmful ways (parasitism). Many factors can influence coevolution, such the frequency and degree of interaction. 00:00 - Chapter 1.
