The relationships between living things are depicted in this primate phylogenetic tree. All primates have large, forward-facing, color-seeing eyes. We also have opposable thumbs with nails instead of claws, which allows us to grasp objects more easily. Primates have relatively larger brains than other mammals. There are many different kinds of primates, each with its distinct characteristics. Understanding today's primates can help scientists understand how we evolved. There are numerous species of primates found all over the world. As shown in this primate phylogenetic tree diagram, some live in Africa, others in Asia, and still more in South America.
