Other primates have a pattern of calls and gestures, but not language as we know it. Primates have hands with five [[finger]]s and flat [[fingernail]]s (most other animals have [[claw]]s or [[hooves]]). All primates are covered with fur (hair), but in humans the body hair is only noticeable in two places: on the head and around the [[genitals]]. Primates are split into two groups: [[Strepsirrhini]] and [[Haplorhini]]. Haplorrhini includes larger monkeys such as, [[tarsier]]s and apes including humans. Strepsirrhini includes smaller monkeys such as [[lemur]]s, [[loris]]es, [[galago]]s (also called bush babies) and the [[aye-aye]]. Primates are one of the few mammal groups which re-evolved full [[Evo
