"The time scale for evolutionary or genetic change is very long. A characteristic period for the emergence of one advanced species from another is perhaps a hundred thousand years; and very often the difference in behavior between closely relatedspecies-say, lions and tigers-do not seem very great...

While the changes are largely of our own making, they cannot be ignored. We must adjust and adapt andcontrol, or we perish."

"In the animal world, on the other hand, the process of evolution is characterised by the progressive discrimination of the animal and vegetative functions, and a consequent differentiation of these two great provinces into their separate departments."

"Since the dawn of time, women have been attracted to mates with strong survival skills-like intelligence and physical prowess-because men with these qualities are more likely to bring home dinner at the end of the day. He stuck his thumbs in the air and grinned. 'Dinner equals survival, team."

"To be awarded a prize which takes its name from an illustrious Dutchman who at the same time was a great citizen of Europe and through his writings did so much to open up our modern world of sensibility and thought is indeed a most signal honour."
