Final answer:
Chimpanzees are omnivorous, eating both plants and meat. Humans have a different diet compared to other apes due to highly processed foods and cooking. Teeth and jaw size differ between humans and other apes due to diet adaptation.
Step-by-step explanation:
Recent research on chimpanzee eating habits indicates that they are omnivorous, eating both plants and meat. However, fruit is the preferred food among all primate species, including chimpanzees, except for humans. Humans have a unique diet that consists of highly processed, low fiber foods, grains, and vertebrate meat. This has led to differences in teeth and jaw size between humans and other apes, as our ancestors may have adapted to eating cooked food.
