Summary Introduction
To determine: Theparental investment and prediction it makes about mate choice.
Introduction: Selection pressure does lead to evolution, but it is not the requirement for evolution to occur. The members that are fit to survive in the changing condition will evolve into a more efficient and improved species.

what are the long term vs short relationships in mate preference?
Much of animal behaviour theory is rooted in optimality, using this theory and thinking about territory size,
construct a well-labeled graph below: sketch two lines (one for costs, one for benefits), with an asterisk (or
symbol of your choosing) indicate the theoretical optimal territory size and in one sentence, explain why that
particular territory size is optimal .
Territory Size
Costs/benefits
Differentiate Kin selection from altruism.
