says it as pre-life). He stressed the purely naturalistic descent with modification. That is complex creatures evolve from more simplistic ancestors naturally over time. In short, as casual genetic mutations take place within an organism’s genetic code, the beneficial mutations are preserved because they aid survival, a process known as ‘natural selection’. These favourable mutations are passed on to then generation.
Darwinian Theory of evolution is a gradual process. Darwin says that, natural selection acts only by taking advantages of slight successive variations; she can never take a great and sudden leap, but must advance by short and sure, though slow steps. Thus Darwin conceded that, “if it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modification, my theory would absolutely break down”.

Darwin compares natural selection with today’s domestic breeding. Over the centuries, human breeders have made remarkable changes in domestic animal populations by choosing individuals to breed. Breeders remove unwanted traits step by step over time. Likewise, natural selection purges inferior species slowly but surely over time.
2.2.3. Evolution Theory and the Degradation of Human Dignity Through the Darwin’s evolution theory biologically, like every other animal, he missed himself in the crowd of his fellow species. Human being was ridiculed as a simple branch of evolution. He was vanished out from the position that, he considered himself as the most dignified creature in the world. Materialistic character of this theory measured man as a mere outcome of evolution. The atheistic reading of evolution possesses a great challenge towards human dignity. Darwin expelled the role of God from creation by proposing the mechanistic evolution.
