We are the last in along line of bipedal Apes. We are Apes, we evolved from Apes, the Apes we evolved from evolved from other Apes. Those Apes evolved from Monkey (not existing ones).
We also have DNA evidence which provides indisputable evidence of our close relationship. DNA tests can show how closely related we are to Chimps, next to Gorillas and the Orangutans. We know this because DNA changes over time and with mitochondrial DNA we can calculate the approximate time of the last common Ancestor. With Chimps, the last common ancestor was about 5million years, with Gorillas around 8 million with Orangutans around 12 million years ago. These common ancestors were neither human nor the modern counterpart ape. They were something different.
Every bone in your body is consistent with its Ape ancestry. A Chimp has every bone you have. Humans are Apes. We are bipedal and intelligent.
