[3] The order was established by Carl Linnaeus in the first edition of his book Systema Naturae (1735) for genera Homo (humans), Simia (monkeys and apes in general) and Bradypus (sloths).
[5] In the 1758 edition of the same book, Linnaeus discarded this name and began to use the word Primates, which has replaced Anthropomorpha completely.
[6] The name is no longer considered valid, as the animals that were included within Anthropomorpha are now believed to belong to multiple clades.
For example, two-toed sloths were included within Anthropomorpha,[7] but are now considered to be in the family Choloepodidae, which is not closely related to the primates.
[8] Comte de Buffon [year needed] correctly rejected the combination of sloths and primates within the same order.
