![]() One gene, for example, called MYH16, contributes to the development of large jaw muscles in other apes. In the past few years, geneticists have identified the loci for some of these anatomical differences. A chimpanzee’s skeletal muscle has longer fibers than the human equivalent and can generate twice the work output over a wider range of motion. But a more important factor seems to be the structure of the muscles themselves. How did we get to be the weaklings of the primate order? Our overall body architecture makes a difference: Even though chimpanzees weigh less than humans, more of their mass is concentrated in their powerful arms. But it is a fact that chimpanzees and other apes are stronger than humans. So the figures quoted by primate experts are a little exaggerated. So he packed up a device used to measure pull strength, called a dynamometer, and set out for the Bronx Zoo. Poe’s story of the scalp-pulling orangutan struck Bauman as being “ grotesquely impossible.” In 1923, he noted that every expert in the field believed apes were vastly stronger than humans-yet none had ever tried to prove it. The suspicious claim seems to have originated in a flapper-era study conducted by a biologist named John Bauman. It’s just the sort of factoid the zoo staff might tell you to keep you from knocking on the glass. If the “five to eight times” figure were true, that would make a large chimpanzee capable of bench-pressing 1 ton. Consider that a large human can bench-press 250 pounds. But it sounds extreme to suggest that humans are only an eighth as strong as chimpanzees. A chimp on four legs can easily outrun a world-class human sprinter. Their climbing lifestyle accentuates the need for arm strength. ![]() Twins are indeed very rare.Pulled scalps? Unstuck wagons? No doubt, chimpanzees are different from us. Scope: The female gives birth to a single young of 1.6 to 2.2 kg. Gestation: Gestation lasts 7 to 8 and a half months. Mating season: They can breed all year round depending on the female’s 36-day menstrual cycle. Sexual maturation: The chimpanzee begins to reproduce between 13 and 16 years old. Its habitat: It lives in humid forests and savannahs: in more or less wooded areas. Protection: The chimpanzee is not really in danger except in a few regions where human activities and diseases lead to regression.ĭistribution Chimpanzee: The wild chimpanzee is found on the coasts and equatorial regions of Africa. It even occasionally hunts birds and mammals (antelopes, wild pigs, small monkeys). ![]() But he also delights in caterpillars, termites, ants, wild honey, bird eggs. This position facilitates the search for food.įood: Its diet is predominantly herbivorous, fruit-eating and grain-eating: leaves, fruits and nuts constitute the basic menu of the chimpanzee. The chimpanzee does not really run since it adopts a swaying gait leaning on its arms. In the wild, chimpanzees can live to be 60 years old. On average adult males are 50 kg and adult females 40 kg, but some individuals reach 70 kg. The male measures 1.30 to 1.70 m in a standing position while the female measures at most 1.30 m. Physical characteristics of the Chimpanzee: He also has a prominent arch and lips while his nose is flattened.Ĭyril-ruoso-chimpanzee-pan-troglodytes-adult-female-with-orphan-baby-she-has-adopted-gabonįamily: Catarhinian hominoid hominidpanine. It has black, smooth skin covered with hair except for the face, ears, feet and fingers of the hand. It is the closest relative of the human being: 98% of the genes of the chimpanzee are identical to those of the human being.
