bodies adapted for climbing trees and also for quadrupedal (four-legged) movement on the ground.moderate sexual dimorphism in which males are slightly larger than females although this is reduced in Bonobos.Chimpanzees are the smallest of the Great Apes and our closest living relatives.
Chimpanzees live in woodland and forests in western and central tropical Africa. There are two living species of chimpanzee – the Common Chimpanzee, Pan troglodytes, and the Bonobo or Pygmy Chimpanzee, Pan paniscus.
a social lifestyle in which about 10–20 individuals live in small, permanent groups. These adaptations include arms and shoulders that enable them to swing from branch to branch (in lighter bodied, young gorillas) finger and toe bones that are long and curved for gripping tree branches and strongly built to support their large body weight and knuckle walking’, in which they support themselves on the knuckles of their hands. bodies adapted for climbing trees (when young) and also for quadrupedal (four-legged) movement on the ground. 
Gorillas are the largest of all primates. Gorillas live in dense forests in western and central tropical Africa. Gorillas There are two living species of gorilla – the Western Gorilla, Gorilla gorilla, and the Eastern Gorilla, Gorilla beringei. a solitary lifestyle except when breeding or when mothers have offspring.occasional use of tools, such as twigs and sticks.a diet of fruit supplemented by insects.These adaptations include very long arms with a shoulder structure that enables them to move slowly from branch to branch (especially in young, lighter bodied orang-utans) and long curved finger and toe bones to powerfully grip tree branches bodies adapted for living in trees which they rarely leave and also for quadrupedal (four-legged) movement on the ground.considerable sexual dimorphism in which the males are about twice as big as the females.Orang-utans live in dense rainforests of Borneo and Sumatra in South-east Asia. There are two living species of orang-utan – the Bornean Orang-utan, Pongo pygmaeus, and the Sumatran Orang-utan, Pongo abelii. There are four types of Great Apes – the orang-utans, gorillas, chimpanzees and humans. Like Lesser Apes, the Great Apes are active during the day. They also have larger brains than other primates. The Great Apes are named for their large bodies. a social lifestyle consisting of small family groups consisting of an adult male-female pair and their juvenile offspring.long, pointed canine teeth and long jaws.
#CHIMPANZEE HAND AND HUMAN HAND SKIN#
hardened pads of skin (callosites) on their buttocks for prolonged sitting. These adaptations include very long arms with a shoulder structure that enables them to rapidly swing from one branch to the next and long curved finger and toe bones to powerfully grip tree branches bodies adapted for living in trees which they rarely leave. body size which is similar in males and females. Gibbons are found in the forests of South-east Asia. These are the gibbons, which live in trees, rarely descend to the ground and are active during the day. There are about 14 species of relatively small-bodied apes known as Lesser Apes. a ribcage that forms a wide but shallow chest. a shoulder and arm structure that enables the arms to freely rotate around the shoulder. distinctive molar teeth in the lower jaw which have a ‘Y5’ pattern (five cusps or raised bumps arranged in a Y-shape). a brain that is larger and more complex than other primates. Great Apes, containing the orang-utans, gorillas, chimpanzees and humansĪpes (including humans) possess the same general features that all primates share but they differ from other primates in a number of distinctive ways.įeatures that separate the apes from other groups of primates include:. There are now only about 20 living species of apes and they are divided into two major groups. Within the last 10 million years, however, many ape species became extinct as the earth’s climate cooled and dried and their forested environments changed to woodland and grassland. The first apes evolved about 25 million years ago and by 20 million years ago were a very diverse group.
