Some call it evolution, And others call it God.

Evolution is written on the wings of butterflies.

Nor do I think we came from monkeys, by the way...That's another piece of garbage. What the hell's it based on? We couldn't've come from anything--fish, maybe, but not monkeys. I don't believe in the evolution of fish to monkeys to men. Why aren't monkeys changing into men now? It's absolute garbage. It's absolutely irrational garbage, as mad as the ones who believe the world was made only four thousand years ago, the fundamentalists.

Why is The Origin of Species such a great book? First of all, because it convincingly demonstrates the fact of evolution: it provides a vast and well-chosen body of evidence showing that existing animals and plants cannot have been separately created in their present forms, but must have evolved from earlier forms by slow transformation.

Natural selection rendered evolution scientifically intelligible: it was this more than anything else which convinced professional biologists like Sir Joseph Hooker, T. H. Huxley and Ernst Haeckel.

I cannot persuade myself that a beneficent and omnipotent God would have designedly created parasitic wasps with the express intention of their feeding within the living bodies of Caterpillars.
