"....i had always thought the theory was that the beetles that survived would be the ones that had the best disguise, and their progeny that had that advantage passed on."

Oh, that IS essentially what happens...[NOT to be confused with Lamarck's theory]....but what has been shown in beetles, as well as other fast breeding creatures that we can observe many, many generations of, is that the process of adaption IS one aspect of an evolutionary process!

Here.. read about one beetle that is at the center of the debate

first, the creationist take
then the scientific answer


then an article about how beetles in general help us comprehend what is happening


What is evident is that those who do not wish to accept evolution are doing what I referred to earlier.... they are doing what is often called "armchair science" and claiming that "it couldn't have happened that way because.... (insert some arbitrary pseudo-fact here". They 'prove' that such & such characteristic MUST have been designed by making up facts that are simply not factual.... or if factual, are not relevant to the case.

"...comparisons of modern creatures with fossils of supposed deep time.
how many examples would you like?"

Fire away with examples... but be aware that I can guess ahead of time that they will be as I mentioned above...non-facts or irrelevant facts. There are just too many interlocking bits of science that support each other in showing that diversity IS a product of evolution.
