Another Graph from the Heretic
We all know how evolution works - selection pressure on a population that has heritable variation. We also know how modern knowledge of training, nutrition,
drugs and so on has allowed athletes to run faster. You may also be aware of the vast amounts of money that is at stake on the Derby. Put it all together and here you have an example of intense selection pressure combined with unlimited resources with one aim - to make a horse that runs faster. You only have to look at the Stud Fees associated with the breeding of winners to see how owners believe in heritability of "fitness". So before you go below the fold imagine what the graph of the winning times will look like.
Yes flat-lined - no improvement for years. The creationists crow it shows that evolution doesn't work, geneticist mutter about limited gene pool and I'm just perplexed.
