What are the differences in the factors between "culture that has fostered innovation" and "culture that has followed tradition"? Artifacts excavated from archaeological sites sometimes show shapes and patterns that are drastically different from those of previous eras, suggesting that technological innovation has occurred. On the other hand, in some cases, there is no change in shape or pattern over a long period of time. There are three possible explanations for these differences, <1> Variations in the presence of members who are creative and imaginative, <2> Variations in the environment that forces innovation necessary for survival, irrespective of the qualities of the members, <3> The result of stochastic chance, independent of the qualities of the members and the need for change. This study aims to investigate whether cultural innovation can be explained by factors such as members' behavioral traits based on genetic factors or environmental pressures for survival. To this end, a novel methodology will be established to estimate the relationship between the level of innovation found in archaeological artifacts and data showing environmental changes and gene frequencies associated with behavioral differences. This study will encourage cooperative relationships with experts in various fields.
