The MNHN’s cultural anthropology collections focus on the interrelationship between human societies and their environment with a focus on techniques, representations, knowledge and know-how. The field is actually threefold, involving ethnology, ethnobotany and ethnoecology. In addition, ethnology deals with the techno-cultural evolution of societies in a context of globalization as well as issues of identity. Ethnobotany illustrates the cultural importance of the vegetal world for human societies. Ethnoecology focuses on objects mediators with natural environment, such as tools, techniques and transformed animal and vegetal material.
