Feminism has been considered to be imcompatible with biological sciences such as anthropology. In particular, minimalism-oriented feminists tend to dislike studies on sex difference. Actually, some biological scientists have been apt to justify the discriminative status quo. However, we should inquire the way for feminism compatible with biological sciences. In addition, we should be aware that feminism asserted to the Third World countries would be in collision with the request for respect of their cultures, and hence with cultural relativism.
