We will see that apes are much freer sexually than lower mammals from nature's confining restraints. Nonetheless, ape sexuality is dissimilar from that of humans. In part that is due to the retention by most ape species of female sexual heat. The use of a communication system in this sense, largely lacking in lower animals, is something that apes share with us. Note that the gestures of apes may differ from those of humans in significant ways.
Chimpanzee gestures seem to be used for imperative purposes to request actions from others . . .
