Are we to believe that a rare overgrowths like this must mean that we once had tails? Personally, I am far from convinced.
It looks to me like a few prominent evolutionists also know better than to push this forward as evidence that we all once had tails.
What about human tails?
by Robert B.
Sometimes evolutionists claim that the rare malformation during embryological development, which results in a protruding clump of skin near the buttocks, is a throwback to when our evolutionary ancestors had tails. But is this really a true tail which develops, or is it merely an embryological deformity caused by a genetic mistake?
Well, these appendages are certainly not true tails, and are usually a fatty tumor having absolutely no relationship with a monkey tail whatsoever. For example, the Indian Tribune reported a case where a Muslim baby in India was born with one of these so-called "tails." They reported that many were flocking to this child because they thought he was a reincarnation of a monkey God within the Hindu religion. Sometime later, doctors were asking to examine the child, because they said it was probably a tumor, and the child's life could be in danger. Not a tail at all, but a dangerous tumor!
Most of the reported "tails" are little more than fatty tissue with no vertebrae. Even if there are bony segments within the appendage, it still relates to genetic mistakes (e.g., certain genes relating to the development of the vertebrae column are erroneously replicated too many times during the developmental process, which results in an artificial "tail" like structure). Most of the time these appendages can be surgically removed without any problems, and that is what's recommended by most doctors.
Many of the prominent and more educated evolutionists usually know better than to tout these abnormal growths as evidence of evolution, because they know it's simply not true. For example, well known evolutionist Dr. Eugenie Scott of the National Center for Science Education or NCSE, said this in a radio debate with Dr. Hugh Ross about alleged human tails:
"Actually, that's [human "tails"] not an evolutionary issue at all ... It's a matter of developmental biology; it's a matter of what happens when that sperm fertilized that egg, and that egg grew into a baby, and that baby was born. I couldn't give you the exact precise biochemical explanation but probably at some point where the genes instructing how many vertebrae to lay down in that vertebral column duplicated itself a couple extra times, by mistake. It was a faulty transmission of information, so to speak. And this particular individual just ended up getting a few extra vertebral segments. And this doesn't happen very frequently, but, you know there are glitches in the genetic material that produce things like this, just as there are glitches in the genetic material that produce people with six fingers. But if somebody was born with six fingers, you don't think 'Oh no! That takes us all the way back to Acanthostega', with the earliest amphibians some of them had six fingers. It's not really an evolutionary issue." -Eugenie Scott, 10-11-1999 on "The Mike Rosen Show"
Dr. Scott, who is an ardent proponent of evolution, knows that this issue doesn't relate to the evolution debate at all. If such a passionate supporter like Dr. Scott doesn't consider this relevant to evolution, then one wonders why others continue to flaunt this malformation as "unequivocal evidence" of evolution. It leaves you to wonder if they are simply trying to play on people's ignorance, and "wow" them with an artificial resemblance of a tail. If an evolutionist resorts to human "tails" as evidence of evolution, then you can probably be sure that they are desperate in their attempts, because they are not tails at all, and they are certainly not evidence of evolution in the slightest.
