![]() ![]() ![]() The differences between subspecies of chimpanzees can be most clearly seen in their behaviors, and the Western chimpanzees is incredibly unique in this regard. This behavior has not been observed in any other subspecies of chimpanzee. Researchers have recently observed a remarkable behavior where Western chimpanzees will craft a spear and stab it into a tree hole in hopes of catching a bushbaby. Males are more likely to eat monkeys while females eat smaller primates such as bushbabies. Male and female Western chimpanzees have displayed different behaviors when feeding. They may lead raiding parties where they hunt a group of monkeys and share their catch with one another. When they can, they will eat birds or other mammals. Chimpanzees are also known to eat tree bark, gum, honey, flowers, and algae when available. Western chimps tend to feed on termites and ants more often than other subspecies, using tools to scoop the insects out of their nests. ![]() Another ten percent is dedicated to leaves. About 50–60% of the chimpanzee diet is made up of fruit, depending on the season. Nonmetric skull features are anomalies in the skull that cannot be numerically measured, but can be observed and described by experts.Ĭhimpanzees are omnivores with a set of teeth adapted to both grinding plants and tearing flesh. Researchers also report that they have dozens of unique nonmetric skull features. Western chimpanzees have rounder muzzles and more prominent brows than Eastern and Central chimpanzees. Chimps have an opposable big toe to help grasp branches. This fact, along with our stronger pelvic muscles and spinal adaptations, is why we can walk upright while chimps can only do so for short moments. This means they have to keep their feet farther apart. While human thighs slope inward, allowing us to keep are legs together and walk upright, chimpanzee thighs are sloped outward. That is to say, our hands have gone relatively unchanged since we separated from chimpanzees, while their hands have developed a structure more suitable to their environment.Ĭhimpanzee legs are far different from human legs. Interestingly, fossil records show that human hands are actually more primitive than chimpanzee hands. Their hands feature long fingers and short thumbs, which are specialized for climbing trees and picking fruit. (By comparison, human arm spans are usually equal to or slightly above our height). The arm span of a chimpanzee is approximately 50% longer than their body length. Like humans, chimpanzees may go partially bald later in life and develop gray hair, particularly around their chin. This bare skin is pink on newborns, but turns black as they get older. Chimpanzees are robust apes covered in thin black hair, except for their faces, hands, and feet, which are bare. As such, we have a great deal in common between our species. Humans and chimpanzees diverged between 4 and 8 million years ago and are our closest relatives.
