Solving Evolution's Greatest Puzzle
Although Darwin could explain how evolution preserves useful adaptations over time, the mechanisms behind its speed and efficiency eluded him. In this radical rethinking of Darwinian evolution, Wagner offers a solution to that enduring mystery. He draws on 15 years of research using the latest experimental and computational technologies to uncover the ‘principles of innovability’ that allow the creation of such complicated adaptations as lactose digestion, camouflage and the ‘antifreeze proteins’ produced by Arctic cod.
