Scientists have found that Illinois was covered by a sea during the Paleozoic Era. Over time this sea was inhabited by animals including brachiopods, clams, corals, crinoids, sea snails, sponges, and trilobites.
Chimpanzees lack the prominent sagittal crest and associated head and neck musculature of gorillas. [14] [39] Chimpanzee hand (left) compared to human hand. Chimpanzee bodies are covered by coarse hair, except for the face, fingers, toes, palms of the hands, and soles of the feet. Chimpanzees lose more hair as they age and develop bald spots.

These are found in all chimpanzees, but in only two out of five gorillas. They are also less prominent when found in gorillas. They are, however, found in primates that do not knuckle-walk.
