Linda S. Gottfredson, 2010:
"But something had to have selected for we human’s highly general ability to learn and reason, so I began searching for evidence and speculation about the earliest Homo sapiens and their environments. What about more basic hunting, gathering, and cooking technologies? A passage in The Promethean Fire (Lumsden & Wilson, 1983) made me realize, with a jolt, that I had falsely equated human innovation with physical technology. Innovation is more basic than that. It is simply having a mind’s eye: that is, being able to imagine something beyond what we are seeing, feeling, tasting or otherwise experiencing in the present moment; to imagine times, events, objects, beings, and circumstances that do not exist now and may never. To become tool makers and technologists we first had to become imaginators, to see beyond the concrete here and now. Recognizing hazards as potential threats to well-being is an act of imagination."
