 From the combination of these two types of research, Terkel was able to analyze the mechanisms involved in this social learning to determine that this eating behavior resulted from a combination of ecology and cultural transmission, as the rats could not figure out how to eat the pinecones without being "shown" by mature rats.Though this research is fairly recent, it is often used as a prime example of evidence for culture in non-primate, non-cetacean beings.Animal migration may be in part cultural; released ungulates have to learn over generations the seasonal changes in local vegetation.
