Euprimates are a group of primates that includes all modern primates, such as lemurs, monkeys, and apes. They are characterized by their larger brains, forward-facing eyes, and flexible limbs, which allow for a wide range of movement. This group is believed to have evolved around 55 million years ago during the Paleocene epoch. The classification of Euprimates is divided into two main subgroups: strepsirrhines, which include lemurs and lorises, and haplorhines, which encompass tarsiers, monkeys, and apes. These primates play essential roles in their ecosystems, often acting as seed dispersers and contributing to forest regeneration.
