While waiting for the bus, now that it’s light out that early, I like watching the birds. They have complex interactions and so many different styles of flying. They have ways that are a closed book to our species. From human eyes they seem so playful that it’s difficult to believe they participate in a struggle for survival. Evolution tells a different story, of course. Living not far from the great human nest of Newark’s Liberty Airport, it’s not unusual to see an engineered flying machine soaring high over their avian heads. Which, I wonder, are the better fliers? Birds, after all, evolved. Flying wasn’t planned, as far as we can tell. Although not so much around here, some birds don’t even fly.
I once read—many years ago and I can’t recall where—that if a person were to fly they would need an enormous chest to beat the very large wings they’d need for lift-off. Birds, apart from being naturally aerodynamic, have hollow bones which make them a touch fragile, but less tied to gravity. Our planes and jets, unlike the escape vehicle in Chicken Run, don’t flap. Bernoulli’s law keeps them aloft, along with some meticulous engineering and heavy fuel consumption. Humans may imitate nature, but they supersede it when they can. Still, I have to wonder why, if birds were a special creation as our literalist friends claim, God didn’t make them more like a plane.
Holding your wings out stiff all day, I’ll allow, would get pretty tiresome. Still, if you’re designing a critter to fly you might as well go with the best parts available, right? If not, I’m going to have a talk with my mechanic and ask for some of my money back. Birds, for all their charm, are very good illustrations of evolution at work. Dinosaurs taking to the air is so poetic that it has an organic feel. Flying is a great way to escape your land-bound predators. That step from long leaping to flying may be a doozie, but it seems to explain the shape of birds better than any intelligent design. Among bipeds, though, only one claims the place of being god-like in shape. Having said that, there are some flaws that a good biomechanical engineer might address. But then, who said God majored in engineering? When I went to college I was firmly under the impression that he’d majored in religion. And that, as many engineers might suppose, is for the birds.

At a hotel during a recent excursion, I saw a National Geographic (I think) special on Gobekli Tepe (this is the fate of those of us kept from a daily sustenance of academic listservs bearing the most exciting news). Gobekli Tepe is an archaeological site in Turkey, discovered several years ago by Klaus Schmidt of the German Archaeological Institute. It is an odd site, dating back to some 11,000 years ago, that consists of megalithic (big stone) constructions earlier than Stonehenge or the great pyramids of Egypt, both dating from the Bronze Age, roughly. The complex of odd buildings seems to be religious in function because they bear no practical purpose, and the implications of the site are that our earliest steps towards civilization have been misinterpreted from the beginning. We have been taught that domestication of plants and farm animals led to fixed centers of living. Gobekli Tepe suggests that religion led to settled life and farming came later.
The implications of this are rather startling for those of us who’d been working on the assumption that religion developed as a way of keeping the gods happy after people had the luxury of surplus food brought on by agriculture. It turns out that hunter-gatherers learned to live in settled locations because of religion. That is, religion, instead of being just another component of culture, is what led to culture in the first place. In a climate where the most vocal intellectuals insist that religion must be shut down, chopped off at the roots, and burned in the oven of rationality, we see that none of us would be enjoying our urban lifestyles if religion hadn’t brought us together in the first place.
There is no doubt that religion may be taken to extremes, and that when it is, it becomes dangerous. Religion, however, is no foe to rational thinking. Gobekli Tepe is a site of astounding engineering for Stone-Age hunter-gatherers. Engineering is applied science, and so these people were using their understanding of the world to establish a ritual site for the practice of their religion. They needed to live nearby, although they still had to spend their days chasing animals and gathering foodstuffs along the way. Religion made them realize that life together was a necessity for humanity to thrive. We should take a more balanced view before declaring religion a source of evil only. We may never be able to coax the gods into the laboratory, but that doesn’t mean that they don’t have a very important function for human civilization. If they are taken in reasonable doses, they might even lead to astounding transformations.
