The Arrival of the Fittest

The power of Darwin´s natural selection is beyond doubt, explaining how useful adaptations are preserved over generations. But the biggest mystery about evolution eluded him: how those adaptations arise in the first place. Can random mutations over a mere 3.8 billion years solely be responsible for wings, eyeballs, knees, photosynthesis, and the rest of nature´s creative marvels? And by calling these mutations ´random´, are we not just admitting our own ignorance? What if we could now uncover the wellspring of all biological innovation? Renowned evolutionary biologist Andreas Wagner presents the missing piece in Darwin´s theory.
