Primate Evolution and Classification

The video explores the classification of primates, focusing on the debate over whether humans are considered monkeys. It explains the concept of clades and how organisms cannot evolve out of them. The video delves into the characteristics of different primate groups, including Strepsirrhini, Haplorhini, and the distinction between New World and Old World monkeys. It concludes with a discussion on apes and the evolutionary relationships among primates.
