Biology

Biologists, when examining groups of non-humans, have observed repeated behaviors which are taught within communities from one generation to the next. Tradition is defined in biology as "a behavioral practice that is relatively enduring (i.e., is performed repeatedly over a period of time), that is shared among two or more members of a group, that depends in part on socially aided learning for its generation in new practitioners", and has been called a precursor to "culture" in the anthropological sense.

Behavioral traditions have been observed in groups of fish, birds, and mammals. Groups of orangutans and chimpanzees, in particular, may display large numbers of behavioral traditions, and in chimpanzees, transfer of traditional behavior from one group to another (not just within a group) has been observed. Such behavioral traditions may have evolutionary significance, allowing adaptation at a faster rate than genetic change.
