Kreativität und Fitness Cliffs:

Gerhard Roth:

"Kreativität ist eine Gratwanderung zwischen zu viel und zu wenig Assoziativität. Viele kreative Menschen sprudeln vor Ideen, und der Schritt zum >Spinner< ist oft klein, und häufig genug fällt es schwer, zwischen Hochkreativen und >Verrückten< zu unterscheiden."

Randolph M. Nesse:

"Racehorses are prone to breaking the cannon bone in their legs. Why didn't natural selection make it thicker? It did; wild horses are unlikely to break their legs. However, breeding only the fastest horses made their leg bones longer and longer, thinner and thinner, and lighter and lighter. Successive generations of racehorses have become faster and faster but also more and more vulnerable to breaking a leg, something that now happens about once every thousand times a racehorse starts a race."
