Dryopithecus is a genus of extinct primates that lived during the Miocene era. They are believed to be the ancestors of both modern-day chimpanzees and humans. Some other names that have been used to refer to these primates include the "Oak Ape" and the "Forest Ape." Additionally, they are sometimes referred to as "dryopiths." These primates were arboreal and adapted to life in the trees, with a high level of mobility and dexterity in their hands and feet. They had a relatively small brain and were herbivorous, feeding primarily on fruit and leaves. The discovery and study of Dryopithecus fossils have provided important insights into the evolution of primates and the development of our own species.
