Nature once provided man with a cave for shelter. It was not designed for the task, it only happened to be there for our use. It was cold, drafty and damp. Water had to be hauled in from a nearby stream. A trip to the bathroom in the middle of the night often meant wading in the snow for a couple of hundred yards each way. A ďŹ re that was warm enough in the cave choked its occupants with smoke. A baby with a bad cold either lived or died. The warmth of a bed of skins was shared with mice and cockroaches. There was some protection from the elements, and for that we were thankful, but it was far from comfortable. It took a while but the human changed things. We now live in comfortable homes with inside plumbing, electric lights, central heat, air conditioning, a two car enclosed garage, and, yes, a television set. The human genome which forms us and, through our instincts, guides us, also happened. It was shaped by the elements in the same manner as the cave. It was only partially designed for our task of that time, of living in that cave. Millions of years of trial and error left us with a genome as primitive as that cave, and it is littered with the genetic garbage of all the genetic failures along the way. It offers a living for most of us, but many
suffer from its inadequacies. The human genome was certainly not designed for modern living, and is now degenerating under an evolution which we have crippled. It’s time we took a hard look at that old cave and see if we can bring it up to modern needs.
