Evolution of new physical traits in mollusks has declined and grown more predictable over time. Early mollusks evolved a unique physical trait once every 2 million years. That frequency began declining roughly 444 million years ago to about one new feature every 9 million years.

“Turbulence is one of the great unsolved problems in classical physics,” Larry Cornman, a senior researcher at NCAR, told me, when we spoke in his office. “You have to predict where these things will happen and when, but the equations are inherently nonlinear.” Cornman is sixty-eight, with brown hair, streaked with gray, that hangs below his shoulders. He was dressed in a T-shirt and a tracksuit jacket, and spoke with an offbeat affability—a holdover from Boulder’s hippie days. Before earning degrees in math and physics from the University of California, Santa Cruz, Cornman lived in a Buddhist commune in Northern California for three years. When he moved to Boulder, in 1983, he took a job at NCAR as a part-time computer programmer, and never left. He has since earned eight patents and devised some of the most widely used systems for detecting turbulence.
