A primate (i/ˈpraɪmeɪt/ PRY-mayt) is a mammal of the order Primates (i/praɪˈmeɪtiːz/ pry-MAY-teez; Latin: "prime, first rank"), which contains prosimians and simians. Primates arose from ancestors that lived in the trees of tropical forests; many primate characteristics represent adaptations to life in this challenging three-dimensional environment. Most primate species remain at least partly arboreal.
