DOES FISH DNA SHOW THEY EVOLVED LIMBS?

The recent news is that scientists have discovered some snippets of DNA from an ancient fish that can cause mice to grow limbs. This is wrongly being hailed as evidence that fish had developed legs. Isn't it interesting that the fish they got the DNA from didn't have legs!

These snippets of DNA from the fish seem to be "triggering" mechanisms. They can only trigger ("turn on") formation of limbs if the genes for limbs first exist, and since genes for limbs exist in mice then these triggering mechanisms, even if from a fish, will work. None of this means fish evolved legs.

Imagine an evolving fish having part fins and part feet, with the fins evolving into feet. Where’s the survival advantage? It can't use either fins or feet efficiently. These fish exist only on automobile bumper stickers!

A partially evolved species, with partially evolved tissues and organs, waiting (supposedly) millions of years to evolve would be unfit for survival.

Genetic and biological similarities between species are no proof of common ancestry. Such similarities are better and more logically explained due to a common Genetic Engineer or Designer (yes, God) who designed similar functions for similar purposes in various species. Genetic information, like other forms of information, cannot arise by chance, so it's more rational to believe that DNA or genetic similarities between species are due to intelligent design.

The genes already exist for micro-evolution (variations within a biological kind such as varieties of dogs, cats, horses, cows, etc.), but not for macro-evolution (variations across biological kinds such as from sea sponge to human). Only variations for already existing genes and traits are possible.
