Primate Classification and Characteristics

The video tutorial explores primate classification, focusing on the traits that define primates and the distinctions between various primate groups. It covers physical characteristics such as opposable thumbs, prehensile abilities, and vision. The tutorial also delves into the differences between strepsirhines and haplorhines, tarsiers and anthropoids, and cercopithecoids and hominoids, highlighting their unique features and evolutionary traits.
