The principles of natural selection.
Behavioral biology is the study of the biological and evolutionary bases for behavior. Modern behavioral biology draws on work from the related but distinct disciplines of ethology and comparative psychology. Ethology is a field of basic biology, like ecology or genetics.

Using the principles of natural selection, _____ attempts to study how behavior and the mind have been shaped over …Overproduction by definition, in biology, means that each generation has more offspring than can be supported by the environment. Because of this, competition takes place for limited resources. Individuals have traits that are passed down to offspring. Some of these traits give individuals an advantage when it comes to surviving to reproduce.
