Behavior is defined as the
collective responses of an animal to its environment. Some behaviors
are inherited, while others are learned.
Biologists study the mechanics
of behavior—what triggers a response and what mechanisms underlie
it—as well as the evolutionary significance of the behavior.
In this Lesson, well look at
different types of behavior and their causes. Well also examine
how behaviors are learned, and how we can tell whether a behavior is
inherited. Inherited behaviors can be traced back to particular
genes, and well investigate the link between molecular genetics
Finally, well look at the
evolution of behavior and how natural selection may influence which
behaviors are inherited and which ones are learned.
