The other night I was watching a debate between an evolutionist and a Int. Design debater. The evolutionist use the Corvette as an example. You see the corvette evolved from the regular Chevy. It grew and became more intricate etc. etc. I once heard the same argument from another evolutionist about how the Wright Bros. first flew in a paper and stick model and now we have evolved into going to the moon. Well, Duuuuuhhhhh. Did it ever occure to these idiots that both of those items evolved from an " outside power" (men engineers) Actually they were making the point for the Int. Design guy. With stupidity like that , Evolution theory isn't going to be doing much recruiting in the future.
I'm sorry you misunderstood their actual points.
And it's a shame that they had to dumb down the actual science by using poor analogies, because the public doesn't have enough background to grasp the biological processes when they are directly described.
