Evolution, we’re told, has one goal: survival. As an unthinking process of nature, evolution “programs” us all to desire survival for ourselves and our offspring. Even attributing that purpose too it is to suggest it’s more a willful agent than a blind process. People, on the other hand, are meaning-seeking creatures and so there’s bound to be some disappointment involved. I was just discussing with a friend how it seems that people just can’t agree on evolution mostly because of the strident claims on both sides. The New Atheists make claims beyond the evidence that survival to reproduce is the “only” role of evolution and we are “just” animals with too much gray matter, and that consciousness is “merely” electro-chemical activity in our brains. Creationists, for their part, say evolution couldn’t possibly account for structures as complex as we see in nature, and therefore a deity much be involved. The rancor grows until both sides end up despising the other. People who look for the middle ground are not newsworthy and fade into the scenery. I wonder if we’re evolved to ever get along.
My wife mentioned that it’s like the Tower of Babel story. Here is the tale of God making humans inevitably talk past one another. We can’t understand and so we argue and criticize and insult. A more scientific explanation might be that perhaps we’ve tipped the evolutionary balance with our species-specific success. We are by tar the most numerous species of any large animal. (At least that we know of.) Having put ourselves as lords and masters of the food chain our challenges have become mental and we turn ourselves to the question of who’s right instead of simple survival. Sacred books can’t guide the discussion, but reason alone. And reason, as we all know, has its limits.
The great irony in all of this is that, if we’re evolved to seek meaning, we’re not equipped to find the truth. As neuroscientists have pointed out, the brain’s function is survival, not truth finding. Our desire to know the truth is a human avocation abstracted from consciousness. We’ve not adequately defined consciousness, but since there aren’t many large predators hunting us down anymore, that brain-power has been diverted elsewhere. Despite all this, we don’t see world peace spontaneously breaking out. Even on a smaller scale we find prejudice and hatred and insane mass production of weaponry when our only predators are ourselves. Evolution, we’re told, has only the goal of survival. Being an unthinking principle, even ascribing it this much conscious decision-making is merely a matter of convenience. Does the Tower of Babel mean we must hate those who differ from us, or does it perhaps suggest that the real goal is better understanding?
