Evolution News reports.
OK, if there was any doubt that Karl Giberson’s tailed-baby photo is a Photoshop creation, that doubt is now dispelled. I emailed the creator of the image, photographer Larry Dunstan, to make sure I hadn’t misunderstood. Yes, confirmed the helpful and candid Mr. Dunstan, it was created with Photoshop using a photo of a tail-free two-week-old baby. The tail is not genuine. It was generated by a computer, not by, as Giberson thought, a “gene for tails.”
The reader who found the source image on the Internet for me, over at Science Photo Library, works in graphic design and 3D modeling. Says reader Ryan, what made him leery was “the lack of shadow from the tail,” and the “framing and composition,” which don’t match what you’d expect from “a photo intended to document a mutation.”
Right. Casey and I had that same gut reaction, but it’s good to have our response confirmed by professionals — again.
[...]Why do I keep harping on this? Only because human origins is an ultimate question and using human “tails” as evidence for common descent is a mainstay of Darwin defenders.
Theistic evolutionist Dr. Giberson is noted for having criticized and broken with other Evangelical Christians over issues having to do with, according to his characterization, intellectual and scientific integrity. See his book The Anointed: Evangelical Truth in a Secular Age.
Is Giberson right to be up on a high horse that way? I’m not a Christian so I don’t have his personal stake in the question. But Giberson, after complaining that my querying his use of this photo was “ad hominem” — which it obviously isn’t — characterizes me (and Casey Luskin) in a way that clearly is ad hominem.
Lest you think I am tricking you about this being used as evidence for evolution, here is Giberson in the Daily Beast reflecting on his debate performance.
I showed pictures of otherwise healthy humans who had been born with webbed feet and tails. I asked the challenging question: “Why does the human genome contain instructions for the production of features we don’t use?” The scientific explanation is that we inherited these instructions from our tailed ancestors but the instructions for producing them have been shut off in our genomes, which is why Shallow Hal is the only person most people know who has a tail. Sometimes the “ignore these genes” message gets lost in fetal development, however, and babies are born with perfectly formed, even functional tails.
Is he right about any of this?
Evolution News explains that he is not:
For now, here’s a crucial fact: even such so-called “tails” aren’t anything like those found in tailed mammals. That is for the simple reason that “true tails” in humans entirely lack vertebrae — or any kind of bone, cartilage, notochord, or spinal cord. As the aforementioned paper in the Journal of Neurosurgery explains:
In all reported cases, the vestigial human tail lacks bone, cartilage, notochord, and spinal cord. It is unique in this feature.2
Other prominent medical research journals agree:
- A 2013 paper in the Journal of Child Neurology states: “True tails are boneless, midline protrusion usually attached to the skin of the sacrococcygeal region and capable of spontaneous or reflex motion. They consist of normal skin, connective tissue, muscle, vessels, and nerves and are covered by skin. Bone, cartilage, notochord, and spinal cord are lacking.”3
- A paper from the Journal of Pediatric Surgery states: “The human vestigial tail lacks bone, cartilage, notochord, and spinal cord. It contains a central core of mature fatty tissue divided into small lobules by thin fibrous septa. Small blood vessels and nerve fibers are scattered throughout. Bundles of striated muscle fibers, sometimes degenerated, tend to aggregate in the center.”4
- An article in the British Journal of Neurosurgery explains: “A true tail in humans is vestigial and never contains vertebrae in contrast to other vertebrate animals.”5
- Most striking of all, perhaps, are the words of a famous paper on tails in The New England Journal of Medicine: “When the caudal appendage is critically examined, however, it is evident that there are major morphologic differences between the caudal appendage and the tails of other vertebrates. First of all, the caudal appendage does not contain even rudimentary vertebral structures. There are no well-documented cases of caudal appendages containing caudal vertebrae or an increased number of vertebrae in the medical literature, and there is no zoological precedent for a vertebral tail without caudal vertebrae.”6
- Finally, an article in Human Pathology explains: “In humans a true tail, is vestigial, however, and never contains vertebrae. … Bona-fide cases of human tails containing bone have not been documented.”7
These observations certainly don’t make it sound like humans can have “perfectly formed, even functional tails.” In fact, it’s difficult to argue that any tail could be called “bona fide” if it isn’t “bone-fied.”
Where did Giberson find the image? In the humor magazine “Cracked”. That’s… chutzpah. I wonder if he used Dilbert comics as evidence in his PhD thesis?
Standard Operating Procedure
I think it’s a bad idea to use images from humor magazines as evidence for your point of view, but I think it’s par for the course with Darwinists, who are still using things like Haeckel’s embryos in science textbooks as evidence of evolution.
Who says? One of the top peer-reviewed science journals “Science“:
Using modern techniques, a British researcher has photographed embryos like those pictured in the famous, century-old drawings by Ernst Haeckel–proving that Haeckel’s images were falsified. Haeckel once admitted to his peers that he doctored the drawings, but that confession was forgotten.
Still used in textbooks, though. It’s “fake, but accurate”.
