Contrary to the Darwinian theory of (genetic) evolution, the Vedas and Prabhupada taught that there is a gradual evolution of consciousness. After aquatic life, punishment exists in the form of the non-moving entities who have to withstand, sometimes for hundreds of years, wind, piercing cold, searing heat, rain and snow and lack of shelter. A further evolution to insects allows them to find shelter by crawling or flying. Then they become birds, then beasts and then finally humans.
