All Todays description on great apesFossils of gorillas and chimpanzees have been found in what is now Africa, while orangutan fossils have been found only in Asia, but humans have been found throughout almost all continents, even in Antarctica, suggesting that Antarctica was warmer than today and was attached to Australia and Africa during the Holocene-Anthropocene. Orangutans and gorillas have been suggested as four-legged intelligent carnivores, with gorillas hunting in large packs like many of today's flightless carnivorous birds, since fossils of gorillas have been found together and are found with sharp canine teeth, but orangutan fossils however was found separated from other orangutan fossils, suggesting that orangutans were solitary killers. Chimpanzees, which were likely partially-bipedal, might have been purely carnivores like most great apes, but it is possible that chimpanzees could have been omnivores. Humans, however, were most likely herbivores, unlike any other great apes, feeding only on fruits, leaves, seeds, nuts, roots, and tubers. Humans were also fully bipedal upright walkers since they had long back legs and short front legs compared to most other great apes, which gave these apes an advantage and spread throughout most of the world's landmasses. They have been found with incomplete tailbones, suggesting that great apes probably had short or long tails. Orangutans, gorillas, and chimpanzees were likely as intelligent as modern parrot, while humans were probably twice as intelligent, making these herbivores among the smartest prey on Earth. There are fossilized remains of gorilla nests in Africa, suggesting that great apes all laid eggs. Great apes were likely cold-blooded and sluggish, so these apes could have likely lived to be around 240-260 years. It is unknown why great apes had became extinct.
Introduction to real life North America
Since real life humans had introduced all todays great apes to real life North America, these animals now coexist alongside real great ape species, including humans. Unlike their ancestors, all kinds of all todays great ape species are now peaceful to any sapient species/beings and to dylanusids, as they adapted into human settlements and learned to tolerate human activities and among others, so they now flourish alongside real great ape species and are now very tame towards any sapient species.
