Scientists decode DNA of ‘living fossil’ fish

Originally posted on The Beast 980:

NEW YORK (AP) — Scientists have decoded the DNA of a celebrated “living fossil” fish, giving them new insights into how today’s mammals, amphibians, reptiles and birds evolved from a fish ancestor.

Scientists used to think the African coelacanth died out 70 million years ago. But then a fish trawler caught one off the coast of South Africa in 1938.

The coelacanth is closely related to the fish lineage that started to move toward living on land. And it hasn’t changed much from its ancestors of even 300 million years ago. The new research found its genes have been evolving remarkably slowly.

Researchers also reported Wednesday in the journal Nature that the animal’s DNA code is already giving insights into the genetic changes needed to move from the water to life on land.

  1. FISH DNA DOESN’T SUPPORT EVOLUTION OF LIMBS

    The recent news is that scientists have discovered that some snippets of DNA from a fish, they once thought was extinct, 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. There are no fossils of such fish. 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.
