Supersport gets taken to school by the author of a paper he was misrepresenting:
Dear Supersport,
This will be my one and only post to this message board. It is my research you are falsely using to support you [creationists] arguments. Please do not reference my work in this way in the future.
Your interpretation of the plastic responses of tadpoles to chemicals produced by predators is false. Much research (not my own, look for research by Robert Denver) has shown that chemicals in the water produced by predators when feeding on prey, or changing environments in general, activate pathways in the body which in turn lead to increased tail size and differentiation of color. It has nothing to do with the tadpoles "desire" to have a larger or redder tail, it is simply a physiological response. The tadpoles have not "evolved" during the course of their development, as you assert. An induced phenotype is not heritable, the ability to induce it is. The tadpoles with the red tails will not produce red tailed tadpoles when they are adults. Those with clear tails will not produce clear tailed tadpoles. They will both produce tadpoles that have the ability to make either phenotype.
