Theories And Intro To Animal BehaviorPresentation Transcript
Start-up: Turn homework into the tray. Have your notebook open, pen/pencil ready, and be prepared to take notes.
In science a theory is… Theory – a well-tested explanation that is supported by a lot of evidence (facts) – involves scientist collaboration Scientific Theories are MORE POWERFUL than Laws because they are made up of many different laws. 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
