Gravity mediates consciousness. The waves of the gravitational fields create matter. Hydrogen cyanide gives rise to prebiotic synthesis of lipids, proteins, carbohydrates, porphyrins and nucleic acids which can all self-assemble to form self-replicating prions, viruses, lipid organisms and carbohydrate organisms. Hydrogen cyanide acts as an interactomic molecule which produces the primitive cell or nanoarchaea. They can form prokaryotes and eukaryotes which can evolve into primates. Hydrogen cyanide acts as the neurotransmitter of consciousness and mitochondria can sense gravity or God. 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.
