The story of Dasavatar is the story of human evolution and Vedic biology. Gondwanaland and Lemuria in the Southern ocean is the cradle of civilisation and the Dasavatar indicates human evolution. This substantiates the evolution of mammals from reptiles and the sequential evolution of egg laying dinosaurs to placental warm-blooded cortical bipedal dinosaurs and Homo neanderthalis the Lord Varaha and Narasimha. The Homo neanderthalis on hibernation evolved into Homo floresiensis and later Homo sapiens as indicated by Vamana. The continent of pygmies and dragons indicate the sequential evolution of dancing primate dinosaur, the singing primate bat and the bipedal primate humans. the dinosauric dragon Naga Asura race and Homo floresiensis pygmies are evidenced from Vedic and Puranic evolutionary biology.
