Clones aren't blank slates, Dresser explains. They're exact genetic copies of another creature. The behaviors that make African wildcats successful hunters in the savannah are, fundamentally, made possible by the activation of just the right gene at just the right time. The first African wildcat whose DNA told its brain, "Hey, eat that field mouse" stood a better chance of surviving and reproducing, and when it did, its offspring inherited that trait and automatically expressed the same survival behavior. "Those genes pass on when you clone an animal, too," Dresser says. "I think our clones' behavior makes a strong case that instincts are at least partly genetic."
