context: Physical anthropology emerged in the 18th century as part of the attempt to classify the human race. [2] The first prominent physical anthropologist was a German doctor named Johann Friedrich Blumenbach (1752-1840) from Göttingen. He collected a large number of human skulls, so he could think of himself as an expert on human diversity. In the 1830s and 1840s, physical anthropology played a major role in the debate on slavery. The scientific work of the British expert James Cowles Prichard (1786-1848) regarded all humans as descendants of the same species (monogenism) and condemned slavery. This work contradicts the work of Samuel George Morton (1799-1851) from the United States who considers humans to be descended from several different species and are not in harmony with one another (polygenism). When slavery in the Western world ended, the debate about this theory was meaningless.
