If humans evolved from apes then why are there still apes?

Humans did not evolve from present-day apes. Rather, humans and apes share a common ancestor that gave rise to both. This common ancestor, although not identical to modern apes, was almost certainly more apelike than humanlike in appearance and behavior. At some point -- scientists estimate that between 5 and 8 million years ago -- this species diverged into two distinct lineages, one of which were the hominids, or humanlike species, and the other ultimately evolved into the African great ape species living today.
