That's about as wrong as you can possibly get. It's not based on evolution, and its not derived from a belief in any divine creature either.
Not directly, but I think it is fair to say that developments in scientific understanding can have significant impacts on social value systems. The idea of evolution in particular has massive implications for how we view ourselves in the world, where we come from, what we are etc.

Evolution combats traditional notions of divine creation, and thus removes one of the main reasons for believing in God. And for many people, moral nihilism or relativism are the natural consequences of living in a world without a God to act as a universal moral arbiter.
