Hello. From my research and understanding of the theoretical scientists projecting about the theory of evolution, the ape sector, including humans, evolved from an Unknown Common Ancestor, also known as UCA. "Among the living primates, humans are most closely related to
the apes, which include the lesser apes (gibbons) and the great apes (
chimpanzees, gorillas and orangutans). These so-called hominoids — that is, the gibbons, great apes and humans — emerged and diversified during the Miocene epoch, approximately 23 million to 5 million years ago. (The
last common ancestor that humans had with chimpanzees lived about 6 million to 7 million years ago.)"
So they say.
There's more but a person has to be honest to understand it.
The 13-million-year-old infant skull may have resembled a baby gibbon

Notice it said "most closely related to the apes," hmmm, most closely related to the apes. most closely related to the apes...yet the classification is as apes. but now most closely related to apes.
