Biological anthropology (also called physical anthropology), then, is an interesting mixture of social studies and biological studies; several other ingredients make it even more fascinating. The present review uses these data for the inference of character evolution along the branches of the primate tree. Below we outline evidence of primates’ understanding of how others perceive the world, and then consider how the evidence from both deception and cooperation fits this framework to give us a more complete understanding of the evolution of social cognition in primates.

Primates are highly social creatures, living in various group structures such as mated pairs, small family groups, or larger groups of multiple individuals. The importance of this group in medical and biological research is well appreciated, and explains the numerous molecular phylogenies that have been proposed. Primates should display self-grooming, feeding and drinking behaviours relevant to the species concerned. Perhaps most commonly known outside psychology are the.

Interactions with other sympatric primates are uneventful (Soini 1988). Primates scamper on the tops of branches, swing beneath them, and even leap acrobatically from tree to tree. Abnormal behavior in nonhuman primates (“primates” hereafter) is often broadly defined as behavior that deviates qualitatively or quantitatively from behaviors performed by conspecifics in their natural habitat (see Erwin, 1979 for an example). In social groups, individual members coordinate their activities, communicate with one another, and interact in both affiliative (friendly. There are over 200 species and 600+ subspecies of primates living today.

The order Primate contains >500 species from 79 genera and 16 families (), with new species continuing to be discovered (2–5), making primates the third most speciose order of living mammals after bats (Chiroptera) and rodents (Rodentia). They generally have larger brains and cortices, and because of higher relative cortex volume and neuron packing density (NPD), they have much more cortical neurons than other mammalian taxa with the same brain size. These two groups themselves have many divergences, with significant. This ape group can be further subdivided into the Great Apes and Lesser Apes.
