Cultural traits are passed from one generation to the next by sharing, learning, symbols, and is transmitted cross-generations
Interdisciplinarity involves the combining of two or more academic disciplines into one activity (e.g. a research project). It is about creating something new by crossing boundaries, and thinking across them. It is related to an interdiscipline or an interdisciplinary field, which is an organizational unit that crosses traditional boundaries between academic disciplines or schools of thought, as new needs and professions have emerged.
Originally, the term interdisciplinary is applied within education and training pedagogies to describe studies that use methods and insights of several established disciplines or traditional fields of study. Interdisciplinarity involves researchers, students, and teachers in the goals of connecting and integrating several academic schools of thought, professions, or technologies - along with their specific perspectives - in the pursuit of a common task. The epidemiology of AIDS or global warming require understanding of diverse disciplines to solve neglected problems. Interdisciplinary may be applied where the subject is felt to have been neglected or even misrepresented in the traditional disciplinary structure of research institutions, for example, women's studies or ethnic area studies.
Dual inheritance theory
Animal culture describes the current theory of cultural learning in non-human animals through socially transmitted behaviors. The question as to the existence of culture in non-human societies has been a contentious subject for decades, much due to the inexistence of a concise definition for culture. However, many leading scientists agree on culture being defined as a process, rather than an end product. This process, most agree, involves the social transmittance of a novel behavior, both among peers and between generations. This behavior is shared by a group of animals, but not necessarily between separate groups of the same species.
The notion of culture in animals dates back to Aristotle and Darwin, but the association of animals' actions with the actual word "culture" first was brought forward with Japanese primatologists' discoveries of socially transmitted food behaviors in the 1940s.
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, was developed in the late 1970s and early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution. In DIT, culture is defined as information and behavior acquired through social learning. One of the theory's central claims is that culture evolves partly through a Darwinian selection process, which dual inheritance theorists often describe by analogy to genetic evolution.
Because genetic evolution is relatively well understood, most of DIT examines cultural evolution and the interactions between cultural evolution and genetic evolution.
