And what magic kept sharks and lil' tree shrews from enviromental pressure, or even competition? No magic at all -- what they show is that evolution is not quite de-facto natural. That is, evolution is not an assumed fact of nature. Judge Jones is wrong and so are Darwinists who want purely naturalistic evolution to be a "fact".
Sharks have evolved into pretty much the ideal form for what they do. They are, essentially, organic guided missiles. Also, to be accurate, the shark species existing today are not the same species that existed 100 million years ago. There have been some changes. But, all in all, it's very difficult to improve on the design of a shark, for what it does.
Up until humans started hunting them en masse, the only thing in the seas that could take on a shark were Orcas.
So, there's no magic. Sharks are an apex predator and there's simply nothing in their environment pushing them to evolve.
The rat squirrel in this article probably occupies a niche where there is no competition. So, there isn't much pushing it to evolve, either.
