Chimpanzees Mother Mourning Her Dead Child

Its often the females who choose the alpha male. For a male chimpanzee to win the alpha status he must gain acceptance from the females in the community as they are the ones who actually dictate the way the lifestyles are set up (the females are the ones who ensure the survival of the next generation; they have to make sure that their group is going to places that supply them with enough food). There are cases where a group of dominant females will oust an alpha male who is not to their preference and rather back up the other male who they see potential of leading the group as a successful alpha male.

Chimpanzees make tools and use them to acquire foods and for social displays; they have sophisticated hunting strategies requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can learn to use symbols and understand aspects of human language including some relational syntax, concepts of number and numerical sequence; and they are capable of spontaneous planning for a future state or event.
