“The behavior of the dinosaurs had always been a minor consideration for Wu. And rightly so: behavior was a second-order effect of DNA, like protein enfolding. You couldn’t really predict behavior, and you couldn’t really control it, except in very crude ways, like making an animal dependent on a dietary substance by withholding an enzyme. But, in general, behavioral effects were simply beyond the reach of understanding. You couldn’t look at a DNA sequence and predict behavior. It was impossible.”
