"Lec 17 - Key Events in Evolution" Principles of Evolution, Ecology and Behavior (EEB 122) The history of life and evolution has been characterized by several key events. These events can be grouped as new hierarchal levels of selection coming into play, as biological units coming together in symbiosis and specialization, or in a number of other ways. Other important events are situations of conflict resolution or information transmission, from the genetic to the cultural level. 00:00 - Chapter 1. Introduction 04:15 - Chapter 2.
