Q.  My twelve year old son is wondering what are the top predators of chimpanzee in the wild? And how smart are Chimps compared to humans? From Jonathon B. on Facebook

A. The top predator for chimpanzees are, unfortunately, humans. Humans kill wild chimpanzee’s for a number of reasons: some people eat them, some people use them in ritual practices, some people kill them because they are very dangerous and have hurt people in their community, some people kill them to defend their crops (chimpanzees often raid farms and steal crops). This situation has been exacerbated by deforestation across Africa, which has squeezed populations of chimpanzees into small forest fragments and pushed them closer to human villages. To answer your second question – chimpanzees, as I’m sure you know, are extremely intelligent, but I am always careful to try and not compare chimpanzee intelligence to human intelligence. It can be very different – equally complex, but different. For example, some studies have shown an even stronger memory and quick recall ability in chimpanzees. However, a chimpanzee will never be able to design a computer or a rocket. This doesn’t mean they are “less intelligent” – only that the way their brains function is different.

Q. It is clear that chimps mourn, but can they shed tears?

A. Though chimpanzees can produce tears, humans are the only species known to shed them emotionally.

Q. How many subspecies of chimpanzees are there? From Neil L. on Twitter

There are 4 subspecies of chimps. They are divided by geography. In West Africa, the Chimps are Pan troglodytes verus. In Central Africa, in places like Gabon and the Republic of Congo, the chimps are Pan troglodytes troglodytes. In Tanzania, Jane Goodall studied a subspecies called Pan troglodytes schweinfurthii. Existing only along the Nigeria-Cameroon border is a subspecies called Pan troglodytes ellioti. Most captive chimpanzees in the US that you might see in a zoo are verus.

Q. How do wild chimps maintain their healthy teeth and gums?  From Clare S. on Facebook

A. Wild chimpanzees often do NOT have healthy teeth and gums. In fact, one of the things that chimpanzees at places like Save the Chimps benefit from is having access to stellar veterinary care. At STC, things like tooth abscesses and cavities are identified quickly and fixed. In the wild, these things can kill a Chimpanzee. It’s one of the reasons that chimps in captivity tend to have a longer life span. Having said that, it’s not all rotten teeth in the wild.  A wild chimpanzee’s diet does a great deal for maintaining healthy dentition. For example, out here at the site in Sierra Leone, the chimpanzees primarily subsist off of fruits with very large pits. When the chimpanzees eat these fruits they also consume and chew on the hard pits. The pits do a good job in scraping clean their teeth. Call it nature’s toothbrush.


Q. Do you see an evolutionary change in the wild resulting from our interference?  From Susan S. on Facebook

A. Great question! We are currently living in an epoch of time that ecologists and anthropologists have termed “the anthropocene” – which is a period where most life on Earth is affected in some way by the existence of humans on the planet (think of penguins that naturally live in southern South America migrating to the Antarctic peninsula due to warming ocean temperatures, then competing with the penguins that normally live in Antarctica). Wild chimpanzees have been extremely affected by the presence of humans – directly and indirectly. Due to deforestation across west Africa, chimpanzees have been squeezed in smaller forest fragments with high population densities. Frequently they live alongside human communities, and in turn, compete with human populations for resources. This has led to frequent encounters between humans and chimpanzees – a situation that usually ends badly for both parties. Many of these forest fragments do not have the nutritional components to support the Chimpanzee populations. However, in many cases, chimpanzees somehow figure it out! Chimps are “smart” enough to alter their strategies to survive in less than optimal environments. In the forest I am currently in, chimpanzees are nesting in the area of an abandoned village. In this area, they are nesting in large non-native fruit trees that were planted almost 100 years ago by the village. These trees give them an additional food source, a good nesting site, and an area where humans no longer go. It is this type of shift in strategy and behavior that is a direct result of human presence combined with Chimpanzee ingenuity. So to answer the question more directly, we see the evolution of ecological strategies in chimpanzees as a direct result of human presence.


Q. Are there matriarchal societies in the primate world? From Mark M. on Facebook

A. Yes, there are. Interesting examples are South American monkeys called Callitrichids (marmosets and tamarins). Instead of single offspring births, they give birth to multiple offspring  at a time. The mother is cared for by the males within the social group. In turn, she is dominant. Even chimp social groups have very dominant females that have a lot of pull within the group.
