Like us, they had different personalities, different aptitudes, different attitudes. This was borne out in many ways, but the classic example that's often used is that something would rustle in the tall grass. Some of our ancestors weren't too concerned, and figured it was merely the wind; but others were more cautious, suspected a panther, and jumped for the nearest tree. Over the eons, and hundreds of thousands of generations, the nonchalant ancestors were wrong (and got eaten) just often enough that eventually, more survivors were those who tended toward caution, and even paranoia. In evolution, it pays to err on the side of caution. The brains most likely to survive were those who saw a panther in every breath of wind, an angry god in every storm cloud, a malevolent purpose in every piece of random noise. We are alive today as a race, in part, because our brains piece random events together into a pattern that adds up to a threat that may or may not be real. As a result, we are afraid of the dark even though there's rarely a monster; thunder frightens us even though lightning is scarcely a credible threat; and we perceive the menace of malevolent conspiracies in the acts of others, despite the individual unlikelihood of any one given example." ...
