Again, science marvels at the way molecules adapt over millions of years, but isn’t there a deeper intent? In our hearts, we feel the impulse to fly, to break free of boundaries. Isn’t that the same impulse nature expressed when insects began to take flight? The prolactin that generates milk in a mother’s breast is unchanged from the prolactin that sends salmon upstream to breed, enabling them to cross from saltwater to fresh. "
