QUOTE: "The ability to breathe air occasionally appeared in the common ancestor to ray-and lobe-finned fish, about 425 million years ago. Then surfactant genes, new nervous system genes, and other innovations enabled lobe-finned fish to leave the water temporarily. Finally, after the African lungfish split off from the lobe fins, the common ancestor of land vertebrates acquired other respiratory and locomotive refinements needed to live out of water."

DAVID: note my bold, as science validates my theory that DNA is prepared for major advances. dhw sneers at my proposal that DNA has built-in planning for future major advances such as fish climbing into terrestrial life. This article is proof-positive the DNA setup for rapid advances is present. It explains the fossil gaps Gould tried to explain.

It had to be prepared for major advances, i.e. the mechanism had to be present – otherwise, if all life has descended from the first cells, the major advances could never have happened! But look at the paragraph I’ve quoted. It offers a complete history – “occasionally”, using existing genes, then new genes and other innovations (but still only temporarily on land), and then more “respiratory and locomotive refinements”, all of which enabled the fish to live permanently on land. I don’t know how “rapid” this process was, but it could have taken millions of years and of generations of organisms adapting to new environments. What is your theory? That 3.8 billion years ago your God provided the first cells with a programme for occasional air breathing, then another for lots of new genes later on, and then another for more refinements? Or did he keep popping in? “I’ll give you some genes for occasional breathing…”. Then a few million years later: “Here are some new ones for you, for temporary breathing.” “Then a few million years later: “Have some more and go and live permanently on dry land.”
