Anthropoids belong to the suborder (the "dry-nosed" primates). They diverged from other primate lineages, such as lemurs and tarsiers, approximately 40 million years ago. Scientists typically divide them into two infraorders based on their geographic distribution and physical traits:
Anthropoids are distinguished from more primitive primates by several evolutionary adaptations: AntropГіide
Compared to the elongated snouts of lemurs or dogs, anthropoids have shorter, flatter faces, reflecting a reduced reliance on the sense of smell. They possess a larger brain-to-body size ratio, supporting
They possess a larger brain-to-body size ratio, supporting complex social structures and problem-solving abilities. Native to Africa and Asia, these primates have
Native to Central and South America, these primates are known for their flat noses with side-facing nostrils and, in many species, prehensile (grasping) tails. Examples include marmosets, spider monkeys, and capuchins.
Native to Africa and Asia, these primates have narrow noses with downward-facing nostrils. This group includes:
