The Anthropological Theory of Johann Friedrich Blumenbach,blished a connection between the two concepts of race and environment by emphasizing the idea of historical development. This idea was to prove of fundamental importance for the evolutionary theories of the 19th century,. even though the assignation of a time-scale to nature put paid once and for aladmission 发表于 2025-3-28 19:48:18
