infraorder of mammals: "higher primates": New World monkeys, Old World monkeys and apes, including humans From Wikiquote, the free quote compendium
The simians (infraorder Simiiformes) are the "higher primates" familiar to most people: the Old World monkeys and great apes, including humans, (together being the catarrhines), and the New World monkeys or platyrrhines. Simians tend to be larger than the "lower primates" or prosimians.
The chimpanzees in the zoos do it,
Some courageous kangaroos do it
Let's do it, let's fall in love.
I'm sure giraffes on the sly do it,
Even eagles as they fly do it,
Let's do it, let's fall in love.
