That is a good question, and one molecular biology can probably soon answer. This critter should go to the top of the list of species to have their genetic code sequenced. It is possible that 425 million years ago it evolved a repair mechanism to limit genetic mutation.
And that is something we might very well want to splice into our own DNA some day

That is a good question, and one molecular biology can probably soon answer.
Recent science has been singular unsuccessful in supplying evidence for any branch of darwinian theory. An excellent book on point is Darwin's Black Box: the Biochemical Challenge to Evolution, which shows how recent advances in biology undermine rather than support the hypothesis of evolution.
