With the first episode of Sir David Attenborough’s new series, Dynasties, airing this evening, I thought it would be appropriate to write about the focus of today’s episode – the chimpanzee. The common chimpanzee (Pan troglodytes) is a great ape found in dry and moist forests and savanna woodlands across West and Central Africa. As many of you will know, chimpanzees are our closest living relatives, sharing more than 98% of our DNA. It is utterly fascinating to me that we are so similar to chimps. However, it is also utterly terrifying that we have let such an incredible species become endangered – habitat loss, poaching and disease are constantly pressuring the chimpanzee population.
It is depressingly unfathomable to me that we are slowly killing this species – our own common ancestor. Chimpanzees are highly intelligent creatures meaning they experience pain. They experience suffering. To think that we are letting one of the most intelligent animals on earth (a species which is even capable of learning human sign language) gradually go extinct is horrifying.
Homo sapiens and chimpanzees share the family Hominidae, along with the bonobo, two species of gorilla and three species of orangutan. Chimpanzees are slightly larger than their cousin the bonobo, weighing up to around 65kg. In the wild, they live to around 35-40 years old (depending on their location and other factors) and can live even longer in captivity. They are covered in course black hair, with bare patches on their face, hands and feet.
Chimpanzees are social animals. They live in troops which can contain over 100 individuals, but usually their groups include between 20 and 50 members. These societies have strict, hierarchies, with a dominant male nearly always at the top. These primates are terrestrial and arboreal, walking on all-fours when on the ground and using their long arms to swing from tree to tree when in the canopy. Amazingly, chimps are one of the few species that uses tools regularly. For instance, they may use rocks to smash open nuts or use sticks to scoop delicious honey out of bee hives!
The common chimpanzee, like us, is omnivorous, consuming a varied diet of fruit, plants, seeds, insects, eggs and meat. They will hunt small-to-medium sized mammals, including other primates using a highly complex and ingenious hunting method. During a hunt, each chimp is assigned a role: ‘Drivers’ (these initiate the hunt and drive their prey forward), ‘Blockers’ (these are positioned below the canopy and race up the trees to block off any strays), ‘Ambushers’ (these hide and ambush prey if they come too close) and ‘Chasers’ (these rapidly move in to make the final catch).
As you can see, chimpanzees are truly magnificent animals and we should be proud that we share a lineage with such spectacular creatures. But as I mentioned, the common chimpanzee is considered endangered by the IUCN, and their population is estimated to be less than 300,000 individuals – an insignificant number when compared to the current human population of 7.7 billion (an estimate made in November 2018 by United Nations). Their population trend is not looking good so we must act before it is too late.
