An Evolutionary Approach by J.C. Steven Gaulin, Donald McBurney. This term means that any member of any species will interact and associate with other members of its same species. The association may produce benefits and costs to both the group and the individual.
Animals are social when being social represents a benefit.
In contrast, if the social behavior represents more costs than benefits, they will develop solitary habits. Techniques that help to avoid predators and food acquisition are examples of the benefits that result from socialization. A group of monkeys or apes is more efficient in finding resources, and less vulnerable to predators. Therefore socialization in this case benefits the survival and reproduction of the species. Orangs are found in large rain forest trees.
