Darwin's greatest achievement was to show that the appearance of purpose, planning, teleology (design), and intentionality in the origin and development of human and animal species was entirely an illusion. The illusion could be explained by evolutionary processes that contained no such purpose at all. But the spread of ideas through imitation required the whole apparatus of human consciousness and intentionality
