If you set out in a spaceship to find the one planet in the galaxy that has life, the odds against your finding it would be so great that the task would be indistinguishable, in practice, from impossible.
Richard DawkinsTextbooks describe DNA as a blueprint for a body. It's better seen as a recipe for making a body, because it is irreversible. But today I want to present it as something different again, and even more intriguing. The DNA in you is a coded description of ancient worlds in which your ancestors lived. DNA is the wisdom out of the old days, and I mean very old days indeed.
Richard DawkinsThe beauty of evolution is that it does provide an explanation of how you can get complexity out of simplicity. It does it by slow, gradual degree. At no point are you postulating the sudden coming into existence of a complicated being.
