On the Phenomena of Hybridity in the Genus Homo is a work by Paul Broca (1824-1880), the French physician and anthropologist who founded the Anthropological Society of Paris and discovered Broca’s area of the brain. This anthropological study reflects the racial science of its mid-nineteenth-century moment, much of which later science discredited. Broca’s lasting fame rests on his neurology; the book is read today as a document of how anthropology once approached human variation. Free PDF download available on BDeBooks.
