It includes all lemurs, monkeys and apes, including humans. 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. , What was the most important factor leading. In primates, some of these new areas took on novel social tasks, such as recognizing faces and the emotions of others, and learning written or spoken language—the very skills that helped to drive the evolution of hominin culture, and, arguably, human intelligence. Since their ancestors lived in the forest, primates have developed adaptations for a more arboreal or tree-dwelling lifestyle, such as bendable shoulders and dexterous hands.

Nonhuman primates have a wide distribution throughout the tropical latitudes, but the numbers of many species are declining steeply. From the first modern attempts to classify primates, scientists have struggled to come up with traits that noun. The primates are divided into two major taxonomic groups: strepsirrhines, which retain primitive characteristics, such as the lemurs of Madagascar and the bushbabies of Africa, and the more derived haplorrhines, that is, the tarsier, monkeys, and apes. Also, like humans, most primates give birth to only one newborn at a time, which entails a larger investment of parental resources (a sea turtle can afford to ignore its hatchlings, by contrast, because only one newborn out of a clutch of 20 needs to reach the water in order to perpetuate the species). The first known supposed primates date to the Paleocene, based on fossils for the genera Plesiadapis, Ignacius, and Palaechthon. Primates are mammals in the order Primates.
