Evolution seems to be the most accepted theory for explaining the development of species. I can not think of any other plausible theory that comes close second in the scientific world Yet, there are more than 1 billion people who do not accept it as real. As I understand it, evolution includes the theory that a species breeds genetic mutations and eventually comes up with qualities that better suit the living and hunting environment. That variation will survive more likely. Darwin found this out when he discovered one breed of animals had 4 different sub species on 4 different islands all different. I spoke to a religious person and he said he didn't believe in it, because everything was too perfect. Somebody had to have designed it. Why are people clinging to religion when we solved the puzzle on human origin ? Is there a reason you don't believe in evolution ? Does believing in evolution make you an atheist ?
