Some call it evolution, And others call it God.

Evolution is written on the wings of butterflies.

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.

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.

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.

Today, we celebrate the fact that this historic document has survived a turbulent five decades, which have seen some of the most extraordinary developments in the evolution of human society. These include the collapse of the colonial system, the passing of a bipolar world, breath taking advances in science and technology and the entrenchment of the complex process of globalisation.
