issue #10 variation. Darwin, and modern biological scientists, all agree that variation is at the heart of evolution. Variation by definition means that not all the life is the same, so they can't all be flawless in every way. This critic is once again trying to way too far with absolutes. A living organism need only be perfect enough to reproduce in the next generation. Even what constitutes a least degree of injury can vary according to environment. A fish eye necessary in a mountain stream is waste of metabolism for a fish in a cave. Minor flaws do tend to disappear over time, not necessarily within one individual or one generation. In a time of growing resources an individual may not need to compete very hard and can establish an expanding legacy of offspring. If times get tough again, those progeny who still exhibit a flaw may find it just a bit harder to make a contribution to the next generation. TP
