Here's why:
* Bovine is a taxonomic classification that refers to the family Bovidae, which includes cattle, buffalo, sheep, goats, and other related animals.
* Primates is also a taxonomic classification, grouping together monkeys, apes, and humans, all of which share certain characteristics like five-fingered hands, large brains, and complex social behaviors.
Just like "bovine" is a broad term encompassing many different cattle-like species, "primates" is a broad term encompassing many different monkey, ape, and human species.
