According to this theory of Darwin all the organisms present on the earth today are due to the evolution, and evolved from a single cell . He said after billions of years ,evolution turns cell into a fish and due to shortage of food they adapted themselves for land and slowly they developed legs and became reptiles after this evolution played its role again and turned reptiles into mammals slowly the mammals turned into monkey and then homosapiens. And most of the scientists believe this , but we can’t deny the fact that from last 3000 years the humans are not evolving them selves why do we need warm clothes in winter and why birds got wings not human. If you read Darwin’s theory it seems that evolution is in the hands of organisms only, when they want to walk they got legs , when they want to save themselves they got wings and when they want to eat leave of long trees they got long legs and neck Humans also tried to fly in the sky since there very childhood but we haven’t got wings. I am not saying that evolution is impossible , evolution is there but it is on a very small scale only. saying that a single cell had converted into a giant animal , couldn’t make any sense to me.
