What caused our species to break out of the pattern set by archaic humans? Again, there were probably many factors. But from my perspective as someone who studies the human mind, one development stands out as of special importance. There is a mental ability we possess today that must have emerged at some point in our history, and whose emergence would have vastly enhanced our ancestors’ creative powers.
The ability I mean is that of hypothetical thinking – the ability to detach one’s mind from the here and now, and consciously think about other possibilities. This is the key to sustained innovation and creativity, and to the development of art, science and technology. Archaic humans, in all probability, didn’t possess it. The static nature of their lifestyle suggests that they lived in the present, their attention locked on to the world, and their behaviour driven by habit and environmental stimuli. In the course of their daily activities, they might accidentally hit on a better way of doing something, and so gradually acquire new habits and skills, but they didn’t actively think up innovations for themselves.
