Refuting Evolution

[popeyespappy]

do you mean that they existed but were eaten by Sharks?

I'm saying you're asking why we don't see a ton of fish that have a critical part of their locomotive system mutated out of its single useful feature. It's the same reason we don't see a ton of tigers that don't have legs; they don't survive. It's not a trait that allows one to even reach maturity in the animal kingdom, let alone breed.

Yes a large part of MS’s argument is a strawman. His understanding of evolution is poor at best. The reason we don’t see fish fossils with legs in the middle of their backs is evolution and natural selection don’t work that way. Functional tetrapod legs don’t suddenly appear over a single generation. The evolution from the fins of lobe fined fish to tetrapod like amphibian took many generations and millions of years.



If a fish with a mutation that resulted in a wrist / ankle like joint in the fin in the middle of its back had been born the mutation wouldn’t have lasted enough generations to develop into a functional leg because it would offer no functional advantage. On the other hand that same mutation to the front fins would allow the fish to do pushups. This type of adaption would eventually allow lung fish to drag themselves out of the water and onto land.
