Turtle history: no shell fossil (Introduction)

QUOTE: "A fossilized turtle discovered in southwestern China fills an evolutionary hole in how the reptiles developed features such as a beak and shell, researchers report on 22 August in Nature. Although the specimen can help scientists to pin down when modern turtles developed such characteristics, it’s also muddied the waters when it comes to illuminating the group’s origins.
"The roughly 2-metre-long animal, dubbed Eorhynchochelys sinensis, lived about 230 million years ago. Its skull is similar to those of modern turtles, whereas the rest of the animal’s skeleton is more like that of a predecessor that lived 10 million years before."

dhw: We should be surprised that any remains are found from 230 million years ago, but when they are found, they provide yet more evidence of links between earlier and later life forms, i.e. of common descent.

DAVID: Turtles have no known fossil sequence, so they are still out of no where. Doesn't prove anything, but they are so unusual in phenotype they are somewhat like whales to create wonder why they bothered to develop.

This article provides a link in the chain of common descent, which you profess to believe in. There are of course loads and loads of missing links. Fossils are rarities. Just this one from 230 million years ago. I’m surprised that you are starting to believe in organisms that come from nowhere, as opposed to coming from other organisms. This would certainly go against everything you learned during your medical training! And I’m delighted to see you wondering why they bothered to develop, which is a clear indication of autonomy. I’d have expected you to wonder why your God bothered to preprogramme them 3.8 billion years ago or to personally dabble them!
