Animal culture
Animal culture can be defined as the ability of non-human animals to learn and transmit behaviors through processes of social or cultural learning. Culture is increasingly seen as a process, involving the social transmittance of behavior among peers and between generations. It can involve the transmission of novel behaviors or regional variations that are independent of genetic or ecological factors.The existence of culture in non-humans has been a contentious subject, sometimes forcing researchers to rethink "what it is to be human". The notion of culture in other animals dates back to Aristotle in classical antiquity, and more recently to Charles Darwin, but the association of other animals' actions with the actual word 'culture' originated with Japanese primatologists' discoveries of socially-transmitted food behaviours in the 1940s. Evidence for animal culture is often based on studies of 
feeding behaviors,  vocalizations, predator avoidance, mate selection, and migratory routes.An important area of study for animal culture is vocal learning, the ability to make new sounds through imitation.
