Lecture Description

Principles of Evolution, Ecology and Behavior (EEB 122) Every species on earth has an environmental range in which it can live. Usually it flourishes in the central portion of this range. Organisms contain a host of adaptations that allow them to manipulate their environments to remain within their preferred range. Plants and animals differ in the nature of these adaptations, which include the control of water, temperature, pH, and ion concentration. 00:00 - Chapter 1. Introduction 08:06 - Chapter 2.
