"Humans march to a faster genetic 'drummer' than primates"
Uh, humans ARE primates. Maybe someone missed the word "other."
"Primates" is a two syllable series of sounds used to refer to a number of animals that share some characteristics according to criteria assigned to that designation. Because of a belief that human beings are an advanced form of that classification of animals, the term is applied to human beings.
By the human beings who believe they are descended from "primates".
