No Pain, No Gain
You’ve heard of “red in tooth and claw,” natural selection, and the survival of the fittest. As one evolutionist put it, “The death of unfit individuals is what causes a species to adapt and improve.” This is because evolutionary theory is founded on that Malthusian idea of limited resources. Life is a zero-sum game. And so when a chance mutation happens to confer a reproductive advantage to one individual, he and his descendants survive and propagate at the cost of others, who do not. It is evolution’s version of a final accounting, but in this Darwinian spreadsheet there is no forgiveness, just survival. Of the fittest that is, and death of the unfit.
And if death is a necessary part of the evolutionary equation, then conflict can’t be too far behind. To wit, evolutionists are now saying that “Fighting may have shaped the evolution of the human hand.” This because they discovered that a clenched fist works pretty well when throwing a punch.
Oddly enough our evolutionary cousins, chimpanzees and bonobos don’t generally clench their firsts and may not be able to do so. Oh well, their loss was our gain. Death, or at least a good rumble, is evolution’s engine of progress.
