Everyone knows what Charles Darwin said. Almost everyone is wrong.

He did not discover that species change; his own grandfather had written verse about that. He did not say we descended from monkeys, and he was careful not to. What he did was stranger and far more dangerous: he removed foresight from the explanation of complexity. Before him, the appearance of design required a designer. After him, it required only time, variation, and the quiet arithmetic of who leaves offspring.

This book follows that idea from a Shropshire garden to the inside of a machine. It argues that Darwin was mistaken for a biologist. His engine mentions no flesh at all—only that something varies, something is copied, and something fails to be copied. Flesh was merely the first place anyone noticed it running. Weismann cut the germ line free of the body. The synthesis gave the rules a physical address. Dawkins pointed out that what is inherited is not the animal but the instruction. And convergence—the camera eye invented twice, echolocation invented twice, both times by creatures with nothing relevant in common—hinted that the good solutions belong to the problem rather than to the lineage.

Then something happened that Darwin had no way to anticipate. A system appeared that carries the whole accumulated content of human thought while inheriting none of his machinery: no reproduction, no death, no variation within its own line. It is the ape's software running on sand, and it settles an old question by accident. The long quarrel between evolution and creation was conducted entirely about the substrate. The interesting object was always the software.
