【How-to】Does bill know george is a monkey

Old World monkeys, except the Barbary macaque, also have tails. Apes (gibbons, siamangs, gorillas, chimps, and orangutans) lack tails, as do humans. This is an important distinction because, as depicted, Curious George has no tail, suggesting he is an ape or possibly a Barbary macaque. So, back to our hero.
