Arrival of the Fittest: Solving Evolution's Greatest Puzzle

â€œNatural selection can preserve innovations, but it cannot create them. Natureâ€™s many innovationsâ€”some uncannily perfectâ€”call for natural principles that accelerate lifeâ€™s ability to innovate.â€

Darwinâ€™s theory of natural selection explains how useful adaptations are preserved over time. But the biggest mystery about evolution eluded him. As genetics pioneer Hugo de Vries put it, â€œnatural selection may explain the survival of the fittest, but it cannot explain the arrival of the fittest.â€

Can random mutations over a mere 3.8 billion years really be responsible for wings, eyeballs, knees, camouflage, lactose digestion, photosynthesis, and the rest of natureâ€™s creative marvels? And if the answer is no, what is the mechanism that explains evolutionâ€™s speed and efficiency?

InÂ Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over fifteen years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.

Consider the Arctic cod, a fish that lives and thrives within six degrees ofÂ the North Pole, in waters that regularly fall below 0 degrees. At that temperature, the internal fluids of most organisms turn into ice crystals. And yet, the arctic cod survives by producing proteins that lower the freezing temperature of its body fluids, much like antifreeze does for a carâ€™s engine coolant. The invention of those proteins is an archetypal example of natureâ€™s enormous powers of creativity.
Â
Meticulously researched, carefully argued, evocatively written, and full of fascinating examples from the animal kingdom,Â Arrival of the FittestÂ offers up the final puzzle piece in the mystery of lifeâ€™s rich diversity.
