Chimpanzees adapt to their habitat by use of their opposable big  toes which help them climb trees. They use their sharp, long teeth  to scare off any predators and their loâ¦ng arms to swing from tree  to tree.
Research has shown that chimpanzees are able to communicate many of the same facial expressions as humans through the complex movements of the facial muscles. In fact, the facial cues were so similar that Ekmanâs Facial Action Coding System could be applied to the chimps in evaluating their expressions.
