TIMING AND COORDINATION OF BEHAVIOR ARE REGULATED BY VARIOUS MECHANISMS AND ARE IMPORTANT IN

NATURAL SELECTION

Essential knowledge 2.E.3:

Ethology is the study of behavior

Two types of behavior:Innate Behavior and Learned Behavior

Individuals can act on information and communicate it to others.

Innate behaviors are behaviors that are inherited; “instinctive” behaviors

A joey climbs into its mother's pouch upon being born.

Innate Behavior

Sea turtles, newly hatched on a beach, will automatically move toward the ocean.

Innate Behavior

Honeybees communicate by dancing in the direction of a food source without formal instruction.

Innate Behavior

Other examples include animal fighting, animal courtship behavior, internal escape functions, and the building of nests.

Learned Behavior

Learning occurs through interactions with the environment and other organisms.

Learned Behavior

shaped through experience (through conditioning, punishment, reward, etc).

Teaching a dog to roll over by giving a treat is an example of a learned behavior.

Responses to information and communication of information

are vital to natural selection.

In phototropism in plants, changes in the light source lead to differential growth, resulting in maximum exposure of leaves to light for photosynthesis.

Responses to information and communication of information are vital to natural selection.

In photoperiodism in plants, changes in the length of night regulate flowering and preparation for winter.

Behaviors in animals are triggered by environmental cues and are vital to reproduction, natural selection

and survival.

• Hibernation• Estivation• Migration• Courtship

Cooperative behavior within or between populations contributes to the survival of the

populations.

Availability of resources leading to fruiting body formation in fungi and certain types of bacteria

The evolution of social behavior in microorganisms

Bernard J. Crespi

Cooperative behavior within or between populations contributes to the survival of the

populations.

Niche and resource partitioning

Cooperative behavior within or between populations contributes to the survival of the

populations.

Mutualistic relationships (lichens; bacteria in digestive tracts of animals; mycorrhizae)

Cooperative behavior within or between populations contributes to the survival of the

populations.
