The Bonobo is the living species that humans are most closely related to (and their relatives the common chimpanzee).

We share a common ancestor and are separated by only a few million years of evolution. Equally evolved, but in different directions.
Bonobos are able to recognize 'self' in mirror and other reflection tests. That's something a human child can't do until they are 18 months old.

See the resemblance?
