ARABIDOPSIS AGAINST EVOLUTION
"Arabidopsis" Versus Evolution, by Cornelius Hunter
The theory of evolution states that biological change occurs by the natural selection of otherwise unintelligent biological variation.
Organisms just happen to vary in their designs, and those that work better are better represented in later generations.
But recent research shows change occurring far more rapidly than such a blind process could generate. The results not only are yet another falsification of an evolutionary prediction, they also demonstrate the limited usefulness of the theory.
The new research used a commonly studied plant, "Arabidopsis thaliana," to study how plants adapt to temperature variations.
In one experiment two generations were exposed to mildly hot temperatures. The next generation was exposed to normal temperatures, and then for the final generation the temperature was again elevated. These plants significantly outperformed plants whose ancestors had been exposed to colder temperatures.
In other words, these plants had adapted to the warmer temperatures, and the adaptation had persisted through a generation exposed to normal temperatures. This example of rapid adaptation defies the evolutionary expectation of lucky changes undergoing natural selection. As one science writer put it:
"Because the chance of accumulating mutations within just two generations that led the heat-conditioned plants to thrive in hotter conditions was essentially nil, the authors conclude that inherited epigenetic factors affecting flower production and early-stage seed survival in those plants had to be at play."
