An Evolutionary Perspective
The forces of evolution are constantly revising both the human genome and the human organism it creates and sustains. This can be a difficult concept to grasp since we are talking about changes across the entire human species, the population of the world, integrated over time, through the passage of many millennia. From the self-centered perspective of our individual lives, in the narrow slit of time within which we exist, evolution can feel like something that “happened” (emphasis on the past tense) rather than something that “is happening”. Those of us who accept Mendelian views of inheritance and Darwinian views of evolution must pause to recognize and respect the current and ongoing remodeling of the human genome and its potential implications.
