Episode 162: Human Evolution

Beginning with primitive Cynodonts in the late Permian, we our evolutionary development through Mesozoic mammaliaforms, the divergence of monotremes from marsupials and placentals, and culiminating in the emergence of primates in the early Cenozoic. Along the way we discuss the emergence of important traits such as the mammalian ear and various primate adaptations for arboreal life. We then discuss the sequence of hominin species in the lead up to to humans, including Ardipithecus, Australopithecus, Homo erectus, and Neanderthals. We conclude with an analysis of the emergence of distinctive human traits, including bipedalism, encephalisation, and extensive tool use.
