Chimpanzees: Our Closest Relatives in the Animal Kingdom
Introduction:
They are an amazing animal. They have a high level of intelligence, elaborate social structure, and diverse emotions. It’s important to note that they share 98.7% of human DNA with us, thus offering insights into our past lives. Commonly found in African forests and savannahs, they are renowned for their agility, tool use, and complex communication systems.
Interesting Facts:
- Closest Relatives: A genetic similarity of approximately 98.7% between humans and them makes them among the closest living relatives.
- They Use Tools: Just like chimps do to retrieve termites from mounds by using sticks or cracking nuts open with stones, which only a few known animals can do this way.
- Very social: It is living among populations of between twenty and one hundred fifty individuals that has led to complex social hierarchies and relationships in them, hence making their societies intricate.
- Sign language: A number have been taught signs as a basic way of communicating, which showed their ability to use symbols.
- Problem solvers: These show signs of being capable of solving problems and often work together as a team towards achieving a common goal, such as hunting down squirrels.
- Emotional depth: Chimpanzees, like human beings, exhibit emotions such as happiness sadness and empathy
- Mirror recognition: This indicates self-awareness by reacting to the own image in the mirror, a trait that is rare in animals.
- Night nests: Every night they make new nests out of leaves and branches on which they sleep.
- Diverse diet: They are omnivorous creatures, meaning that they eat fruits, leaves, insects, and sometimes meat.
Habitat and Food:
Habitat:
They are found naturally occurring in forests and savannahs across equatorial Africa, stretching through 21 countries. They can live in different habitats, including;
- Rainforests: With a lot of food sources available here, chimps find it easy to survive.
- Savannahs: Open woodlands and grasslands allow them to go after prey on ground level.
- Gallery Forests: These forests along rivers and streams are important for their survival through water provisions and diverse plant species.
Food:
Chimps are omnivorous mammals and thus have mixed diets.
- Fruits and nuts: They mainly feed on figs, bananas, and berries, among others.
- Leaves and seeds: Different leaves as well as stems and seeds are eaten by them.
- Insects: Ants, termites, and other insects provide protein sources to these animals.
- Meat: During certain times, smaller animals like birds or monkeys can be caught by them, which they then eat together to reveal their cooperative hunting skills.
Appearance:
They are medium-sized primates with easily recognisable physical features:
- Size: Male adults stand at about 3-4 feet tall when upright with weights of between 88-130 pounds, whereas females tend to be slightly smaller in size.
- Body: They have a strong muscular body covered with short black or dark brown hair, with the exception of the face, hands, and feet, which remain bare-skinned.
- Face: The faces may appear pinkish to brown-black colourations even when wrinkled up.
- Arms: Their limbs are long, strong arms that allow them to easily climb branches or move from one tree branch to another.
- Feet and Hands: In addition to making precise gripping possible, opposable thumbs and big toes enable the use of tools as well.
- Posture: Even though most of the time chimpanzees walk on all fours, they can also walk short distances on their hind limbs.
Types/Subspecies of Chimpanzees:
These varieties are grouped according to the places they live:
- Central Chimpanzee: Rainforests in Central Africa.
- Western Chimpanzee: West Africa is home to this subspecies, which is endangered.
- Eastern Chimpanzee: East Africa, including countries like Uganda and Tanzania, houses eastern chimpanzees.
- Nigeria-Cameroon Chimpanzee: With its habitat restricted to Nigeria and Cameroon, this kind of chimpanzee has the smallest population numbers.
Predators and Threats:
Natural Predators:
Since chimpanzees exhibit complex social behaviour as well as intelligence, they have few natural enemies. Though there are times when they get hunted by:
- Leopards: They ambush one at a time, particularly if it’s a young individual.
- Birds of Prey: These species may prey upon infants of chimpanzees.
Threats:
Chimpanzees face numerous threats from people like;
- Habitat Destruction: Logging, agriculture, and urbanisation cause deforestation that leads to habitat loss.
- Poaching: primarily, it is the poachers’ acts in the forest areas where these animals live that cause bush meat hunting and illegal sale of pets, focusing mainly on chimpanzees.
- Disease: Their populations have been hugely affected by diseases like Ebola and human transmissible infections.
- Climate Change: This threatened their lives as well as changes in food availability and ecosystem alteration.
Mating and Reproduction:
Chimpanzees practice polygynandry; both sexes have multiple partners:
- Mating Behavior: Males are attracted to swollen genitalia, which signal female readiness for copulation at this stage of primates’ reproductive cycle.
- Gestation: The gestation period lasts for about 230–240 days, ending in the birth of a single offspring per pregnancy.
- Parental Care: Mothers nurse, cuddle, and defend their infants for up to 5 years.
- Lifespan: In their natural habitats, chimpanzees survive for approximately 30–40 years, whereas they can exist in captivity up to 50–60 years.
How they Communicate:
Chimpanzees communicate through an advanced system of vocalisation, facial expressions, and gestures.
Vocalisations:
- Pant-Hoots: For example, loud calls are used to recognise individuals or indicate group unity, among other reasons.
- Screams: Expressions of fear or pain that are shouted loudly or shrilly.
- Grunts: An indication of happiness or submission where someone emits short sounds resembling those made by pigs when they breathe out air with force from their nostrils.
Gestures:
- Hand Claps: They use applauding using hands so as to get attention or start playing.
- Pointing: Indicating direction of things or food.
- Hugging and Kissing: They show love and enhance bonds between them in order to maintain relationships.
Facial Expressions:
- Smiles: Playfulness or submissiveness expressed by facial smiles among chimpanzees
- Frowns: Indicate dissatisfaction and being perplexed among members of this species
Movies Featuring Chimpanzee:
- Bedtime for Bonzo: A 1951 comedy where a professor attempts to teach human morals to a chimpanzee named Bonzo.
- Planet of the Apes: The world is ruled over by intelligent monkeys, including Chimpanzee’s 1968 science fiction classic.

FAQs:
Q: Why are chimpanzees considered close relatives of humans?
A: Chimpanzees share 98.7% of their DNA with us and are one of the closest genetic relatives.
Q: Where do chimpanzees live?
A: From West to Central and East Africa, that is across equatorial Africa, forests and savannahs are homes for chimpanzees.
Q: Are chimpanzees endangered?
A: Yes, habitat loss, poaching, and disease have threatened the survival of these animals, so conserving them would be a good idea.
Q: Do chimpanzees use tools?
A: Yes. For example, long sticks are taken by chimps, which they then poke into termite mounds or nuts that require stones to be smashed open.
Q: How do chimpanzees communicate?
A: Communication between individuals is vocalised in the form of screams or barks depending on different situations as well as non-vocal stages such as body movements where raising eyebrows means being a threat, among other ways reflecting social complexities.
