Evolutionary Biologists Have Pointed Cogently to Examples of Cooperative Behaviour

Evolutionary biologists have pointed cogently to examples of cooperative behaviour in animals. An example that supports this argument is:

A) socially learned behaviour that one observes to survive in the environment.
B) mutually cooperative behaviour that has positive outcomes for the cooperator as well as others.
C) self-reinforcing behaviour through an analysis of cultural norms.
D) cathartic behaviour to help kin who are healthy or sick until they are healthy again.
