Professor

48:27·2009·undergraduate level

This lecture identifies pivotal evolutionary events, categorizing them by the emergence of new hierarchical selection levels and the formation of symbiotic relationships. It covers transitions from non-life to life, the development of early cells, and the role of conflict resolution in information transmission.

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.
