| Outline of Final Research Achievements |
Culture is the phenomenon that distinguish the human beings from the other animals. Systems of human knowledge, such as language, symbols, technology, mathematics and sciences, have gradually evolved through the transmissions from the previous to the next generations, and eventually reached high level which cannot be attained by a single individual in a generation. This is called the cumulative cultural evolution. In this study, I focused the role of transmission processes for culture to evolve cumulatively. Through a series of laboratory experiments and agent-based computer simulations, it was found that transmission processes cannot be the mere imitation of the previous generation but it needs to provide an effective selection pressure for culture to evolve cumulatively.
