DNA. Is there anything it can’t do? For many decades anthropologists have built painstaking methods to trace developments in human culture. Those of us who’ve studied linguistics in any fashion remember well the many times instructors corrected our false cognates and pointed out family trees of languages that showed who came from whom, based on subtle shifts of orthography or some other aspect of philology. Entire careers could be made in ancient Near Eastern studies by shuffling around the way words were formed and speculating about how they influenced one another. Then DNA. A recent story in the New York Times demonstrates that DNA studies now tell us whence came the Europeans. Among the three groups that eventually settled in Europe were agriculturalists from the Near East, coming along at just about the same time as the Sumerians show up in southern Iraq. They joined the hunter-gatherers already in situ. Their languages, however, did not dominate as a third group, from western Russia showed up and gave (according to DNA) many of the groups their base languages. And here I thought Latin and Greek and Anglo-Saxon had something to do with it.
No doubt we’ve benefitted much from learning about DNA. We can fight diseases that were mysterious, if not divine, in previous centuries. We can learn how closely we’re related to other animal species, or even the neighbor next door. Sneaky fathers can be determined with a precision that sometimes puzzles, such as the recent story of twins who had different biological fathers. Without DNA such a thing could only have been a myth. I wonder, however, what we’re losing in terms of humanity. I suppose we’ll still need a few archaeologists to dig up the remains for scientists to date. And many traditional cultures will still insist that the human remains uncovered be reinterred and not probed and prodded, even after death. We’ll call them backward and superstitious. We’ll consult the genome and decide who to marry.
Meanwhile some hopeless romantic will insist on sitting off in a corner and composing sonnets to the woman he irrationally loves. Looking at the nighttime sky, he may compare her to the beauty of the moon. We know it is a lifeless rock trapped in our own gravity, mechanically reflecting the light of a burning ball of hydrogen and helium 93 million miles away. And if she’ll run this cotton swab across the inside of her cheek we might well be able to tell if she’s a good choice for mating purposes. We’ll also be able to determine the origins of her ancestors and remove a great deal of the mystery about her—there! Won’t that be better than having to woo her and find all that out for yourself? And when your children grow up you’ll point them to the STEM disciplines, since that is the only direction in which there is any human future. And the anthropologists can join scholars of religion as we wait for someone to put the soup in our bowls.
