This chapter relates to the emerging field of evolutionary psychology. Building on past research understanding of the mechanisms underlying animal behavior is presented. Current researches in this field offer many insights into the development of social behaviours displayed among humans. The contribution of animal behaviour research to unravel the evolution of individual and social behaviours including foraging strategies, reproductive systems, social behaviour, dominance hierarchies, social communication, parental investment patterns, evolution of eusociality, among others, are highlighted. Finally, the applications of animal behaviour studies in the area of wildlife such as conservation, management of national parks, and zoo management are indicated. It may be noted that the developments in the area of animal behavior are impressive and are perhaps as good as noted in allied disciplines of anthropology and zoology. However, animal behaviour research is currently an underdeveloped field of psychology. India could perhaps rejuvenate its close association with animal world and nature, a main part of its mythology and real life, by developing this area.
