Meanwhile, Carl Linnaeus (1707–1778), the physician, botanist, and zoologist, established the taxonomic bases of binomial nomenclature for fauna and flora, and was a pioneer researcher in biologically defining "human race". In Systema Naturae (1767), he established five human-race taxa: (I) the Americanus, (II) the Asiaticus, (III) the Africanus, (IV) the Europeanus, and (V) the Monstrosus, based upon geographical distribution and skin color. Each race possessed innate physiognomic characteristics: the Americanus were red-skinned, of stubborn character, and angered easily; the Africanus were black-skinned, relaxed, and of negligent character; the Asiaticus race were yellow-skinned, avaricious, and easily distracted; the Europeanus were white-skinned, of gentle character, inventive mind, and bellicose; and the Monstrosus were mythologic human sub-races.[13] The sub-races were the "four-footed, mute, hairy" Homo feralis (Feral man); the animal-reared Juvenis lupinus hessensis (Hessian wolf boy), the Juvenis hannoveranus (Hannoverian boy), the Puella campanica (Wild-girl of Champagne), and the agile, but faint-hearted Homo monstrosus (Monstrous man) sub-races: the Patagonian giant, the Dwarf of the Alps, and the monorchid Khoikhoi (Hottentot). In Amoenitates academicae (1763), Linnaeus presented the Homo anthropomorpha (Anthropomorphic man) race of mythologic, humanoid creatures, such as the troglodyte, the satyr, the hydra, and the phoenix, incorrectly identified as simian creatures.[citation needed]
This page, while it has some problems, highlights the history of scientific racism and how these ideas have been used by politicians and the public to justify genocide, ethnocide, slavery, segregation, etc. It also should give some idea of how these deeply entrenched attitudes linger in our society and continue to have some effect on continuing inequalities.
