As continuing from the Bull Ring:
Bull Ring - Another Evolution vs Creationism Debate
This is now open to all posters as per
S.J.'s and my agreement.
Refrain from trolling or derailing this thread please. This isn't a political debate, so stay on the subjects in the context of their scientific merits. Also, no ad hominem or insults.
We request that all arguments be made in your own words: if you understand the arguments then you can make them in your own words without cut and pasting.

My last post on the subject from the Bull Ring debate:
Adaptation is evolution, like I wrote earlier. Common ancestry is inferred, which is a perfectly legitimate scientific process.
Let me illustrate for you how the inference works and why it is so widely accepted: you aren't identical to your parents. Your children are/will not be identical to you. Play that out over hundreds of thousands of generations and the very last one of your line will not even be recognizable as the same species as you if the traits favored for the survivalof your line (in other words naturally selected) are not the traits selected for when it came to you. That's why a few ancient species still remain, they fit their environment very well and their environment hasn't changed. Any mutations were not selected for and the species are largely the same. But that is the exception.
DNA is essentially code. Anything can and does corrupt that code, i.e. cancer, viruses, birth defects, congenital defects, etc. If a particular species' code is corrupted enough times over enough years, it will no longer be recognizable as that species. Go long enough and it won't be recognizable as that genus. Even more time, let's say 200 million years, and the original DNA will code for an organism for which we don't even have a kingdom classification.
Remember that the categories into which we place animals are entirely in our minds. Carl Linnaeus came up with the current system based on morphology and it works very well for when we need terms to discuss biology and organisms. However, all organisms belong to a single, fluid, changing process called life.
