There are a few species of apes, including us: Chimps, bonobos, gorillas, humans and orangutans. They have all evolved in their own way.
The cool thing is that the early homosapien walked the earth with another species that walked on two legs but it is believed that the homosapiens killed them off. Weird huh? Imagine having two species alive right now. One more intelligent than the other and the other would be stronger.

Basically we share an ancestor with the great apes, you can think of them as cousins or siblings with a common "parent", they evolved to deal with the changes of their environment in a different way than the sapient line (our line) did. We still find extinct leftovers from the early sapients, the Neanderthals being a common example, they died out likely because they were poorly suited to the Earth's environment post ice age.
