Hi dcs,
Your comments, which seem to me like gotcha games, are getting tiring for me. There are no conflicts in what I said.
As I’ve explained: evolutionary theory can make tentative predictions about an animal’s approximate first appearance in the fossil record. But you never know when you’ve found the first one. Future discoveries can find earlier ones. Trilobites, for instance, stuck around for 300 million years.
My argument could use a little clarification here though (practicing biologists care to chime in?), because the odds are pretty low that something will stick around in exactly the same form from 375 million to 10 million years ago. Trilobites, for instance, were a diverse group — though we laymen tend to group them together — and different varieties of trilobite were found during different geologic periods. Even the tuatara, a celebrated “living fossil” that’s the only remaining member of a very ancient, very diverse group, has changed a lot over the last 220 million years since its line broke with lizards and snakes. So, you know, you could decide after reviewing the evidence that you want to call tuataras a “missing link” between reptiles in the crocodile-dinosaur-bird-turtle lineage and reptiles in the snake-lizard lineage. But if you found a given individual fossil specimen from among the close prehistoric relatives of the modern tuatara, I would imagine current evolutionary models could give you a pretty good idea what rocks you’re likely to find that tuatara relative in.
It’s a matter of likelihood here, though. Finding something that doesn’t confirm current models and timelines doesn’t mean the entirety of evolutionary theory is wrong. It just means we didn’t understand that particular lineage very well and now we understand it better. The thing is, compared with YEC, at least evolutionary theory has a model, a story for how life unfolded with new innovations at specific times dated in MYA. It can tell you in fine-grained detail when certain traits emerged in the fossil record, and it’ll be pretty close to accurate. YEC… well, let’s not go there.
As to “progression,” I meant, yes, at least order of appearance. There’s significantly more to it than that, but I’m a nonspecialist running on a sleep deficit and facing a long to-do list so I don’t have time to research enough to elaborate further.
I rest my case by repeating my previous point that the fact of evolution does not depend on your strange car-based straw man logic. It is buttressed by the results of 150+ years of inquiry in diverse scientific subfields. If one of my lines of reasoning fails… great! I have a half dozen more independent, strong, unassailable reasons to believe in evolutionary creation.
I may not be up for another round of gotcha questions, but you’re welcome to try.
