What is the difference between Anthropoids and Prosimians? ‘The ancient teeth and jawbones of the tiny, monkeylike creatures shed new light on the poorly understood evolution of early anthropoids, a suborder of primates that includes apes, monkeys, and humans.’ ‘However, if present day anthropoids are any indication, early primates were quick to take advantage of these new arboreal plant foods.’ Primate - Primate - Classification: Traditionally, the order Primates was divided into Prosimii (the primitive primates: lemurs, lorises, and tarsiers) and Anthropoidea (the bigger-brained monkeys and apes, including humans).
