Primate Facts

A bit about our closest relatives:

Primate Facts —> Just how egocentric are human beings? Well, it’s telling that “primate,” the name employed for this order of mammals, is Latin for “first rank,” a not-so-subtle reminder that Homo sapiens considers itself the pinnacle of evolution. Scientifically speaking, though, there’s no reason to believe that monkeys, apes, tarsiers and lemurs–all of the animals in the primate order–are more advanced from an evolutionary perspective than birds, reptiles or even fish; they just happened to branch off in a different direction millions of years ago.

Until recently, naturalists divided primates into prosimians (lemurs, lorises and tarsiers) and simians (monkeys, apes and human beings). Today, though, the more widely accepted split is between “strepsirrhini” (wet-nosed) and “haplorhini” (dry-nosed) primates; the former includes all the non-tarsier promisimians, and the latter consists of tarsiers and simians. Simians themselves are divided into two major groups: old world monkeys and apes (“catarrhines,” meaning “narrow-nosed”) and new world monkeys (“platyrhines,” meaning “flat-nosed”). Technically, therefore, all human beings are haplorhine cattarrhines, dry-nosed, narrow-nosed primates. Confused yet?
