Using the taxonomic system created by Linnaeus in the eighteenth century for classifying living organisms, we may see humans as animals, vertebrates, mammals, and, most important, as primates. Primates may be generally defined as large-brained, tree-dwelling mammals with three-dimensional vision and grasping hands who produce few offspring at a time but take extended and direct care of those offspring, preparing them to live in groups. Like each of the existing 200 primate species, the human primate exhibits its own unique version of the primate theme. Humans have extremely large brains with the ability to create cultures with complex symbolic communication systems, are completely terrestrial, and, unlike all other primates, are habitually bipedal. We also display some differences in our sexual behaviors that are connected to these other characteristics. |
