Evolution is central to our understanding of Biology; it helps us explain both the diversity and commonality in organismal form, function and behavior that have been generated over 3 billion years of life on Earth. We will discuss the mechanisms of evolution within populations and between species, examine some branches of the tree of life and learn how the tree is generated, discuss how phenotypes arise from genotypes and interactions with the environment, and how development is central to understanding evolution.

Animals share needs such as eating, breathing, moving and reproducing. Yet their solutions to meeting these needs are incredibly diverse, constrained as they are by each group's evolutionary history and by the specific demands of the environment in which they live. By looking at the range of solutions animals have devised to navigate life on earth, we will explore fundamental themes in physiology including homeostasis and the relationship between structure and function.
