Detailed explanation-1: -Many social behaviors of animals are adaptive, meaning that being social ultimately increases an animal’s fitness-its lifetime reproductive success. One example of how social behavior is adaptive is aggregation against predators.

Detailed explanation-2: -Behavioral Adaptation: Actions animals take to survive in their environments. Examples are hibernation, migration, and instincts. Example: Birds fly south in the winter because they can find more food. Structural Adaptation: A characteristic in a plant or in an animal’s body that helps it to survive in its environment.

Detailed explanation-3: -Behavioral adaptations are the things organisms do to survive. For example, bird calls and migration are behavioral adaptations. Adaptations are the result of evolution. Evolution is a change in a species over long periods of time.

Detailed explanation-4: -The basic idea behind this standard is that there are group behaviors that can increase the survival and reproductive rate of a population. Group behaviors likely evolved because populations of social organisms share a large portion of their DNA.

Detailed explanation-5: -Group behavior has evolved because membership can increase the chances of survival for individuals and their genetic relatives.
