Mr Achilles D'Sylva
Some say in case of human beings the evolution is now complete. That is to say there will be no further evolution for human beings. It means they would remain as they are until the end times. However, don’t we still share some characteristics with the lower species; such as we have nails, hair and teeth which lower species too have? What according to you would be the fate of human in evolution? Would they lose hair, nails and teeth in the next stage and turn divine?
