How Legs Evolved: Acompañado de Otros Muchos Cambios

Spread the love

report today on new research out of Spain on embryonic development of zebrafish reads “From Fish to Man: Research Reveals How Fins Became Legs.” In this study evolutionists altered the expression levels of some regulatory genes resulting in deformed fins. The idea is that the deformed fin is taking its first step toward evolving into a tetrapod limb, and that this significant evolutionary transition was due not to an altered protein changing the way fins are built, but rather a change in the levels of existing proteins. As one of the researchers explained:  Read more

    They are not even close to rationally explaining how limbs came about. This following video is a bit more sober in illuminating the complexity that evolutionists are up against as to providing a rational explanation:

    Three-dimensional limb joint mobility in the early tetrapod Ichthyostega : Published online 23 May 2012 – video with article
    Excerpt: The origin of tetrapods and the transition from swimming to walking was a pivotal step in the evolution and diversification of terrestrial vertebrates.,,, We conclude that early tetrapods with the skeletal morphology and limb mobility of Ichthyostega were unlikely to have made some of the recently described Middle Devonian trackways.

    lol!

    Or then again, it might be taking it’s first step towards extinction given that these fish lost the ability to swim!

    Which idea seems more reasonable?

    Questions for these “scientists”:

    1. How do you know this?

    2. How can you test this?

    3. Is this science if it is not testable?

    This video specifically focuses in on the complexity of the supposedly ‘primitive’ forelimb:

    OT: Paper Lays to Rest “Vernanimalcula,” Supposed Precambrian Ancestor of Bilaterian Animals – Casey Luskin – December 10, 2012
    Excerpt: In a 2005 paper in Scientific American, University of Southern California paleontologist David Bottjer crowned Vernanimalcula as the “oldest fossil animal with a bilateral body plan yet discovered.” Because Vernanimalcula was dated to tens of millions of years prior to the Cambrian explosion, his article used the fossil to attack the view that the Cambrian explosion was any kind of an “explosion” at all:,,,
    Now, however, a new article in Evolution & Development has taken Bottjer’s arguments about Vernanimalcula to pieces. The authors don’t just question whether Vernanimalcula was a bilaterian ancestor — they’re not even sure it represents a fossil, period.
    Titled “A merciful death for the ‘earliest bilaterian,’ Vernanimalcula,” the article unmercifully concludes that “There is no evidential basis for interpreting Vernanimalcula as an animal, let alone a bilaterian.” The scientific paper uses uncommonly strong language to refute the idea that Vernanimalcula was a bilaterian ancestor, calling that interpretation “fallacious.”,,,

    Too funny!

    Check this out I have to evos arguing FOR baraminolog:

    A cat is a member of the family Felidae. Its parents were Felidae, and its grandparents, and all its ancestors going back tens of millions of years. All of the descendants it leaves will be Felidae.

    A dog is a member of the family Canidae. Its parents were Canidae, and its grandparents, and all its ancestors going back tens of millions of years. All of the descendants it leaves will be Canidae.

    and

    The cat genome is an extrmely specific and masively imporbable code. The chances that the dog genome will evolve into it by random chance is phantasically improbable. Like, try-to-picture-how-tiny-an-atom is small.

    OK which came first- the legs or the butt? Or did they emerge together?
