Blind fish walking

Spread the love

From Science Daily:

Researchers from New Jersey Institute of Technology (NJIT) have identified unique anatomical features in a species of blind, walking cavefish in Thailand that enable the fish to walk and climb waterfalls in a manner comparable to tetrapods, or four-footed mammals and amphibians.

The discovery of this capability, not seen in any other living fishes, also has implications for understanding how the anatomy that all species need to walk on land evolved after the transition from finned to limbed appendages in the Devonian period, which began some 420 million years ago. More.

Actually, it won’t help us understand how the anatomy evolved because that is a historical question. What’s really interesting is that so many fish could have had the anatomy but don’t.

Note: Another type of walking fish, not to be confused with this one.

    More interesting still, some creature had the anatomy to walk but apparently got bored and then decided to swim again

    The pelvic bones (supposed Vestigial Legs) of whales serve as attachments for the musculature associated with the penis in males and its homologue, the clitoris, in females. The muscle involved is known as the ischiocavernosus and is quite a powerful muscle in males. It serves as a retractor muscle for the penis in copulation and probably provides the base for lateral movements of the penis. The mechanisms of penile motion are not well understood in whales. The penis seems to be capable of a lot of independent motion, much like the trunk of an elephant. How much of this is mediated by the ischiocavernosus is not known.
    In females the anatomical parts are smaller and more diffuse. I would imagine that there is something homologous to the perineal muscles in man and tetrapods, which affect the entire pelvic area – the clitoris, vagina and anus.
    The pelvic rudiments also serve as origins for the ischiocaudalis muscle, which is a ventral muscle that inserts on the tips of the chevron bones of the spinal column and acts to flex the tail in normal locomotion.

    Whale sex: It’s all in the hips – Sept. 8, 2014
    Excerpt: Both whales and dolphins have pelvic (hip) bones, (supposed) evolutionary remnants from when their ancestors walked on land more than 40 million years ago. Common wisdom has long held that those bones are simply vestigial, slowly withering away,,,
    New research from USC and the Natural History Museum of Los Angeles County (NHM) flies directly in the face of that assumption, finding that,, pelvic bones serve a purpose,,,
    “Everyone’s always assumed that if you gave whales and dolphins a few more million years of evolution, the pelvic bones would disappear. But it appears that’s not the case,”,,,
    Dean collaborated with fellow co-corresponding author Jim Dines,,, on a painstaking four-year project to analyze cetacean (whale and dolphin) pelvic bones.
    The muscles that control a cetacean’s penis – which has a high degree of mobility – attach directly to its pelvic bones.,,,

    In the following video, Philip Gingerich, the paleontologist who discovered and reconstructed Rhohocetus, which has been called by some evolutionists, ‘the most spectacular intermediary fossil in whale evolution’, states this about that, “most spectacular intermediary fossil”,,,

    “Well, I told you we don’t have the tail in Rodhocetus. We don’t know for sure whether it had a ball vertebrate indicating a (tail) fluke or not. So I speculated (that) it might have had a (tail) fluke.,,, Since then we found the forelimbs, the hands, and the front arms, the arms in other words of Rodhocetus, and we understand that it doesn’t have the kind of arms that can be spread out like flippers are on a whale.,, If you don’t have flippers, I don’t think you can have a fluke tail and really powered swimming. And so I now doubt that Rodhocetus would have had a fluke tail.”

    Making up missing links with plaster and body parts from other creatures – April 2014
    Excerpt: The two scientists who found the lion’s share of walking whale fossils essentially created the best fossil proof of evolution using plaster models and drawings and supplied these to museums and science magazines. In each case, they started with incomplete fossils of a land mammal. Whenever a fossil part was missing, they substituted a whale body part (blowholes, fins and flukes) on the skeletal model or skull that they distributed to museums. When these same scientists later found fossils negating their original interpretations, they did not recall the plaster models or drawings. Now museums are full of skulls and skeletons of ‘walking whales’ that are simply false.” Dr. Werner went on to say, “I suspect some curators are not aware of the significance of these substitutions nor are they aware of the updated fossils. Museums should now remove all of the altered skeletons, skulls and drawings since the most important parts of these ‘walking whales’ are admittedly made up. Museums will also have to delete these images from their websites as they are misleading the public.” –

    More “Design of Life” Evidence: Whales – Oct. 4, 2015
    Excerpt: More About the Male (Whale’s) Refrigeration System
    The system actually works better when the whale swims hard. How can that be, when the testes are located right between the abdominal swimming muscles? It’s like trying to keep a refrigerator cold between two furnaces.
    It works because the blood pumps harder during exercise, allowing more heat to escape into the water through the dorsal fin and tail. The higher volume of cool venous blood then enters the “miraculous web” (Latin rete mirabile, read more here) between the abdominal muscles, where the heat from the arteries is transferred to the cooler veins before entering the testes. It’s a marvelous solution: a “counter-current heat exchanger” (CCHE) mechanism.
    As Richard Sternberg and Paul Nelson explain in the film, without both internal testes and the refrigeration mechanism existing simultaneously, natural selection would halt, and whales would have gone extinct. Females, too, have a CCHE to protect the young during pregnancy. Similar CCHE systems are found in other marine mammals such as manatees and seals, providing more unlikely examples of “convergent evolution.”

    BA77:

    Evolution is a fact. Didn’t you get the memo? 🙂

    More seriously, that admission by Gingerich about Rodhocetus, is simply devastating to the Darwinist’s account. Inside their heads, cognitive dissonance must be off the chart!

    The most sensible interpretation of this “walking fish,” is that the information for building a ‘walking’ structural frame for a vertebrate is already there in the genome, and that it simply needs to be ‘triggered.’ This gets us back to ‘front-loading’ once again.

    When we say, “Necessity is the mother of invention,” this might not be any truer than in species around the world.

    Jonathan Wells on pop science boilerplate – April 20, 2015
    Excerpt: Based on my reading of thousands of Peer-Reviewed Articles in the professional literature, I’ve distilled (the) template for writing scientific articles that deal with evolution:
    1. (Presuppose that) Darwinian evolution is a fact.
    2. We used [technique(s)] to study [feature(s)] in [name of species], and we unexpectedly found [results inconsistent with Darwinian evolution].
    3. We propose [clever speculations], which might explain why the results appear to conflict with evolutionary theory.
    4. We conclude that Darwinian evolution is a fact.

    First this is a old story.
    Rock climbing fish was known long ago in S america. Not blinds ones either.
    Yet this makes a great point for creationism.
    Remember that INTERMEDIATE , Titaaak or something found by a guy who got a NOVA episode out of it.
    That creature was said i think, to be a fish with legs. it was found in the rock layers where they wanted it to be.
    THE yEC answer to these things is always they are just a type within a spectrum of a KIND.
    so these blind catfish etc with leggy bits show this equation. They show a spectrum includes rock climbing fish.
    IF this blind catfish was found in fossil they would say AHA there is your intermediate.
    Yet this living thing is not a intermediate but just another dumb catfish with leggy bits.
    no big deal.
    It proves the failure of the titaaack thing as evidence as a intermediate or at least there is another option.
    leggy catfish is a trivial adaptation and unrelated to a evolutionary trail.

    Find more leggy fish please!!!
