The new world is north and south america and the old world is europe and asia. Hominoids are the greater and lesser apes. Hominins is a subgroup of hominoids including humans, pan, & and ancestors that we share. Hominoids include humans, chimpanzees & bonobos, gorillas, orangutans, and the gibbons. A definitive way of identifying hominoids is they have y5 cusp pattern in teeth. Hominoids are very big compared to other species. The dental formula reflects the number of teeth in the mouth. Each of us has 2 incisors, a canine, 2 premolars, and 3 molars. In humans we have a 2,1,2,3 pattern in each quadrant. Humans and all other hominoids have a 2,1,2,3 dental pattern. Most walk on four legs and anatomy will reflect this.
