What is evolution?

You ask: What evolution?

Look at all the beasts and plants — where they come from? Caveman explain. Every baby born little bit different from parent, from tiny copy-mistakes in the body-recipe. Some difference help — sharper tooth, warmer fur, faster leg. Beast with helpful difference live longer, make more babies. Beast with bad difference die before babies. So helpful trait get passed on more, bad trait fade away. No one choosing — just who survive and breed. Do this ten thousand thousand times, over long long time, and small changes stack into big change. Fish-thing slowly become land-thing. All beasts, all birds, all people share old, old grandparent — Caveman and the hairy tree-ape still carry near ninety-nine parts in a hundred of the same body-recipe. Cave wisdom: life not made all at once — it slowly shaped by who live long enough to make babies.
