Each has his own tree of ancestors, but
Primates
They are so like us. They share over 90% of the same DNA sequence. We look at any primate mother and baby, and we experience the same set of feelings as when we see a human mother and her child. They are social animals, highly intelligent, adaptable, and because of these traits they are often quite dangerous. Studying any member of the primate family is like looking into a mirror, and we may not always like what we see!
