That is a false statement, but it is a widely held belief.
Every critter on Earth will exploit it's environment to it's best abilities. Over time, if something works, then that ability will be passed down through it's generations. If it was a failure, then the parents will die and nothing will survive.
Sometimes, getting rid of "excess baggage" will help a critter to survive. This article presented a good example of how this was done, and why.
I have always been rather neutral about this issue. However, just like "Global Warming", I demand that everyone be honest with the facts that they present.
Once again, did this article demonstrate how intelligence can alter DNA?
No, the article proves that darwinist expectations are wrong again. ID scientists predict frontloading, whereas the Church of Darwin predicts evolution from the simple to the complex. Seeing how sea anemones are thought to precede the Cambrian explosion, this article flies in the face of Darwinist expectations (and to their credit they admit it). Of course, they omit the fact that IDers have predicted frontloading all along, but such behavior is to be expected from nature worshiping darwinists.
