No but a bottom dwelling swamp fish might get fins that, over a long time, increasingly help it to maneuver on the bottom by becoming more leg like. In fact, that’s what the fossil record shows. Further, the organism might find that going further toward the land is helpful in avoiding predators and over time you get amphibians. I’m oversimplifying but that’s what fossils show happened. With very few land animals, laying eggs on shore would have been an advantage in survival. Of course this happened over a long time. Some came in rather quick spurts but most over millions of years. Having a new land environment and plenty of oxygen brought quick proliferation of species.

Too many assumptions about mutations. You state that the fossil record shows that mutations are "how it happened", when to be fair the record simply shows "what was" - it doesn't demonstrate process.

But even this discussion makes huge assumptions about something as basic as the reproduction of mutations - that it simply "happens".

Again, we're discussing an existing system - reproduction. How did cells "learn" to reproduce? How could a cell reproduce a mutation - if reproduction has not yet been developed?

Which brings us full circle. We're back to the requirement that it takes a chicken to produce an egg. Which is kinda the point of this article - that life was engineered...
