Sample text

This kind of backward-reasoning, in which adaptations are seen as having a purpose in some great transcendental game that lasts for millions of years, is also widely seen in schemes of human evolution that suppose, for example, that humans stood on two legs in order to free up the hands for making tools, to nurse babies, and so on. This style of reasoning, in which evolution is assumed to have a pur- ALL ABOUT EVOLUTION 41 pose or a goal, is naturally accompanied by an assumption of progress, very much in the pre-Darwinian style.

Thus was born the concept of evolution as a process of development, elaboration, and, with it, revelation—that is, the deliberate transformation, by the action of unrolling, of a closed scroll to an open one whose information might be read: an orderly dance from simplicity into complexity. Medieval Latin texts use the term to refer to the passage of time during which any metaphorical unrolling might take place. The first recorded use of the word “evolution” in English was in 1616, ALL ABOUT EVOLUTION 29 in a translation of the Tactics by the second-century Greek military historian Aelian (Aelianus Tacticus), where it means, quite specifically, the movement of forces from one position to another: The nature of this Euolution is clearely to leaue the File-leaders in front, and Bringers-vp in reare.

Let’s try this thought experiment. Imagine that by some divine grace (because you’d get it no other way) you were granted knowledge of the complete history of every individual creature that ever lived—its offspring, its ancestors and descendants—and could draw the true tree of life, that is, what actually happened. Just to make things simpler (and more relevant to our current concerns), you restrict yourself to drawing the true tree of hominin evolution, back to our common ancestor with chimpanzees.
