We are not the same folks who marched out of Africa. Our genes have co-evolved with our inventions. In the past 10,000 years alone, in fact, our genes have evolved 100 times faster than the average rate for the previous six million years. This should not be a surprise. In the same period we domesticated the dog (all those breeds) from wolves, and cows and corn and more from their unrecognizable ancestors. We, too, have been domesticated. We have domesticated ourselves. Our teeth continue to shrink, our muscles thin out, our hair disappears, and our molecular digestion adjusts to new foods. Technology has domesticated us. As fast as we remake our tools, we remake ourselves. We are co-evolving with our technology, so that we have become deeply co-dependent on it. Sapiens can no longer survive biologically without some kind of tools. Nor can our humanity continue without the technium. In a world without technology, we would not be living, and we would not be human.
