There are large areas of human experience to which bioscience as we know it today cannot easily or adequately be applied or applied directly. Some fields of biology-related inquiry, for example anthropology, demography, human ecology, history of medicine and disease, and social aspects of psychology, assist understanding of human behavior, individual and social. Where applied to human experience, however, these sciences are rarely able to employ experimental methods and must have recourse to research more like that of the social sciences and humanities. For discovering biologically influenced trends in human societies, comparative studies of human experience in historical depth offer a limited but instructive resource.
