The human brain is a product of natural selection. In the face of scarcity, our hominid great-great-uncles were unable to compete against our sapient great-great-grandparents' abilities to build more elaborate mental models and orchestrate their bodies' movements in more sophisticated ways.

In a knowledge economy, natural selection favors organizations that can most effectively harness and coordinate collective intellectual energy and creative capacity.

Natural selection is anything but random.

Natural selection eliminates and maybe maintains, but it doesn't create.

Natural selection shaped the human brain to be drawn toward aspects of nature that enhance our survival and reproduction, like verdant landscapes and docile creatures. There is no payoff to getting the warm fuzzies in the presence of rats, snakes, mosquitoes, cockroaches, herpes simplex and the rabies virus.

We have stopped natural selection from purifying the species because deep in our heart of hearts, we are all terrified that we won't make the cut.
