Consciousness and Evolution
As Margulis and Sagan (1995) observe (echoing similar, earlier thoughts by Erwin Schrödinger), " If we grant our ancestors even a tiny fraction of the free will, consciousness, and culture we humans experience, the increase in [life's] complexity on Earth over the last several thousand million years becomes easier to explain: life is the product not only of blind physical forces but also of selection in the sense that organisms choose. . ." (Scott, 1996).
