THE CHIMPANZEE

Correct common misconceptions

Humans have descended from apes

Humans are primates

The human species, contrary to what has long been thought, has not evolved from apes. Indeed, it is part of the great family of primates. More specifically, humans form a family called the Hominids along with bonobos, gorillas, orangutans and chimpanzees!

Some species of this family are genetically very closely related. For instance, humans and chimpanzees share at least 98.4% of their DNA, making chimpanzees one of humans’ closest cousins.

Natural habitat

Wild chimpanzees are present on the African continent, particularly in Central Africa.

They are found in the large equatorial rainforests and African savannahs of the continent.

 

Ecology

Chimpanzees are great lovers of edible leaves, insects, seeds, fruits and even sometimes small hunted mammals – making them omnivorous.
A chimpanzee has a lifespan of about 50 years in the wild and in captivity, a chimpanzee can live up to 60 years. As an adult, a male chimpanzee can weigh up to 70 kg and measure 1m20 in the bipedal position, i.e. standing on his own two feet.

The growth period of a chimpanzee is long, almost comparable to humans’. An individual is mature and completes its development at around 13-15 years of age.
A female gives birth about every 5 years. Her gestation period is 8.5 months and she nurses and cares for her youngster for 4-5 years. During this time, the baby remains very close to its mother.

Like humans, chimpanzees have opposable thumbs, not only on their hands, but also on their feet. Their gait is most often on all four limbs, but they are also able to walk in the bipedal position for short distances.

Chimpanzees live in groups that can range from a dozen individuals to sometimes a hundred, under the direction of one dominant male.

They communicate with each other often and in a form very similar to that of humans. They kiss, hug, pat each other on the back, touch hands, tickle each other… They even laugh while playing! They communicate as well with vocalizations and even with facial expressions.

Chimpanzees practice what is commonly known as delousing: they regularly groom each other, which helps build relationships within the community and eases tensions between individuals. So, they are not looking for lice!

If chimpanzees are so similar to humans, why can’t they talk?

It all comes down to the larynx at the back of the throat. Their morphologies are not the same and this organ is involved in speech.

Importance of chimpanzees for the forest

Chimpanzees play an important role in the protection of the forest: because of their long lifespan, their long journeys (several kilometres a day) and their consumption of fruits, they ensure the dissemination of seeds which is essential for the regeneration of the forest, as well as indispensable natural pruning.

If the chimpanzees disappear, the entire ecosystem of a forest will be endangered. Unfortunately, today, chimpanzees, like other great apes, are threatened by extinction.
