"Prediction: no wheels would be found in living things.
The famous evolutionary population geneticist, J.B.S. Haldane,
proclaimed in 1949 that mutations and natural selection (neo-Darwinian evolution) could never produce “various mechanisms, such as the wheel and magnet, which would be useless till fairly perfect.” But ‘wheels’ far more sophisticated than Haldane could have imagined, such as subcellular rotary motors, have been discovered.
A related prediction: there would be no magnets in living things, for similar reasons. Haldane was wrong about that too." CMI
