Some scientific theories: -Theory of Gravity -Theory of Plate Tectonics -Theory of Evolution -Germ Theory -Cell Theory -Atomic Theory

The Study of Animal Behavior (ethology)‏ 1. What an animal does as it interacts with its environment 2. The evolutionary purpose of why it does it

There are Immediate and Ultimate Causes of Behavior Immediate causes – answer “how” questions ex. -how is the behavior initiated? -how long does the behavior last? -who performs the behavior? -when is the behavior performed? Ultimate causes – answer “why” (evolutionary) questions -why does this behavior increase the animal’s likelihood of surviving and reproducing in its environment

You are an Ethologist Activity Your task is to study 10 behaviors Identify an immediate cause of the behavior Identify an ultimate cause of the behavior
