David Campbell managed to slip evolution into the high-school science curriculum in the conservative Florida town where he teaches — by using images of Mickey Mouse through the years to illustrate the principle:
On the projector, Campbell placed slides of the cartoon icon: one at his skinny genesis in 1928, one from his 1940 turn as the impish "Sorcerer's Apprentice," and one of the rounded, ingratiating charmer of Mouse Club fame.
"How," he asked his students, "has Mickey changed?"
Natives of Disney World's home state, they waved their hands and called out answers.
"His tail gets shorter," Bryce volunteered.
"Bigger eyes!" someone else shouted.
"He looks happier," one girl observed. "And cuter."
Campbell smiled. "Mickey evolved," he said. "And Mickey gets cuter because Walt Disney makes more money that way. That is 'selection.' "
