Is Survival of the Fittest a Tautology (a vacuous circular statement)?
In practice, most of the time, yes. I.e., the fitness is not independently measured for later correlation with Survival rates. Rather, survival is assumed to be due to fitness, and fitness coefficients are calculated based on survival rates. In other words… why did the organism survive? Because it was fit. How do you know it was fit? Because it survived. This is circular irrationality, not science. To break this circularity, it is necessary for the Darwinist to independently measure the fitness, and independently measure the survival rates, and then match the two. In most cases, this is not done.
