Communities tend to get along reasonably well with each other however the Common chimpanzee tends to show more antagonism toward outsiders than do bonobos. Community size can range from 15 to 150 members all seeming to share some social bond. Females do not develop strong social bonds with each other like the males do. All adult males are dominant over all females. Chimpanzees and bonobos can stand upright and are well adapted for arboreal activities where they do most of their feeding and sleeping.Ĭommon chimpanzees are very social animals and have a male-bonded society. Body proportions are otherwise similar and both sexes have prominent genitals. Males of both species are 20 to 30% larger than females, and have bigger canine teeth which they use in severe fights. Both sexes will often have a short white beard. The hair on the head may grow in many directions, and both sexes are prone to partial baldness early in maturity. After about the age of 20, they will develop gray hair on their backs.
COMMON CHIMPANZEE WEIGHT SKIN
At maturity, the overall skin color is dark, and the fur varies from deep black to light brown.
COMMON CHIMPANZEE WEIGHT PATCH
Younger animals have flesh-colored ears, nose, hands, and feet, and a white patch near the rump. The face is usually bare and generally black in color. Both species have large brains (300-400cc) and are equally relative to their body size. Their arms extend below the knees when the animal is standing and has a spread that is about 50% greater than the animal’s height. They have highly mobile shoulder joints and long arms, opposable thumbs and opposable big toes that make it easy for precision gripping. Both have stout bodies with backs sloping evenly down from shoulders to hips. Even though they have a more slender body and different shaped head than the common chimpanzee, they weigh as much as the smallest of the subspecies. The bonobo, has in the past, been referred to as the “pygmy chimpanzee and this is a misnomer. the Common, and bonobo, are more prevalent. Of the several subspecies of chimpanzees in the wilds of Africa. schweinfurthi) and one which has not been given a common name (P.t. troglodytes), Long-haired chimpanzee (P.t. There are four subspecies of the Common chimpanzee. This isolation and change to a lowland tropical forest habitat, resulted in their evolving into a separate species. Bonobos then diverged from ancestral chimpanzees about 1.5 million years ago, when a group of them moved south of the Congo River and became an isolated population. From that point forward however, a divergence took place and led to modern gorillas. From analyzing extensive genetic evidence, we shared a common ancestor about 6 million years ago. Common chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) are considered our closest living relatives by a majority of the scientific community.
