E. O. Wilson
"In humans, the trajectory that took us from bacteria to fish to reptiles to mammals including primates has left an indelible mark. Our archaic brains, which served us so well during our evolutionary past, now threaten our very existence. While our smart-brains have given us modern technology and science and the privilege of understanding not only ourselves but our universe, our primal brains are stuck in the stone-age."
