You proposed ALL of geologic evidence contradicted front loading. I cannot think of one and so assume you have no idea what you are talking about.
"I can present no data, therefore you're wrong."
Let's start big: The entire fossil record. Traits always follow evolutionary lineages. This is hypothesized via phylogenetic trees, and is proven via paleontology. Some great work just came out concerning sauropod head morphology, for example. While convergent evolution does make grossly similar features, careful examination alway shows the evolutionarly lineage of the features (look at wings, the ear, tail morphology in predators, etc). If front-loading were true one wouldn't expect novel traits to arise and continue in such a fashion; it would be much more haphazard.
ETA: Also, the fact that you cannot present evidence for the hypothesis you're supporting should cause you to question your hypothesis. MY evidence was presented yesterday, in the other thread, in the form of those books you STILL refuse to read. Shall I call you a fraud, a liar, and childishly insult you, or is that something only you're allowed to do (you know, like interpreting papers on subjects you have no knowledge of)? I've ALREADY presented the evidence, you merely refuse to actually look at it.
ETA2: Before we continue, please demonstrate that you actually have studied paleontology. I have--the referneces I posted are evidence of it, as is my job. I'll take your word for it if you say you've got a job as a paleontologist, or if you say you have a degree in the subject; but please provide something, so that I know you're actually qualified to discuss paleontology. Otherwise, admit that you have not, in fact, studied the subject, and are not an expert. I don't care one way or the other--your argument is wrong either way--I just want to you to recognize that you have NOT studied the subject, and are currently attempting to tell someone who HAS what the data mean.
