Guessed wrong. Try again.
Ledley made it clear it was only a growth and not a tail.
"As a matter of fact, even a superficial reading of Ledley's article makes clear that this so-called tail was no tail at all but was nothing more than an anomalous growth coincidentally located in the caudal region."
Evolution and the Human Tail
Hardly. Ledley, a geneticist, with both success in resesearch and bio-tech start-ups, indeed concludes --
as nearly all geneticists do -- that the rare case of children born with the beginnings of a tail does indeed show a connection between humans and our more primative ancestors.
But that's then parsed (read: distorted) by ICR, a junk "science" (Creationist) misinformation enterprise, which is not where thinking people go for better insights into the natural world. It's for you folks, who due to your yearning for legitimacy of your faith in the face of so much scientific fact contradicting your religious dogma, who will gobble it up, no matter how convoluted or absurd in its conclusions.
So the real question (rhetorical) is: why all the doubt about creation, from "Believers." Why do you need the pseudo-science horseshit to validate your faith. Why not simply believe and leave it at that. (tip: you have doubts; it's not people who accept the truth of evolution who have doubts.)
And if it'll help, perhaps I can explain in ways that are easier to grasp:
Let's say I have a hangnail, bite it off, and then spit it out. It's rife with my DNA, within the myriad cells. So why does it not grow into a copy of me? Bear in mind, it has my entire genome. Answer: no mechanisms controlling the genes. They're turned off, and are not being instructed to turn on, in sequence, and for a precise amount of time.
So when traits are weeded out, like a tail, and the genes for the tail lie dormant, for millions of years, then by
rare chance, one is turned on due to a highly unusual anomoly in the protenome of certain individuals, it's not in proper sequence nor for the precise amount of time that is required for a complete tail as would have been the norm, millions of years ago. It's like a faulty lightbulb, flickering on before going out, permanently.
So you see, genes, and the immense Human Genome Project, merely scratches the surface. It's like a tool box, without the carpenter, which in the case of living organisims, are proteins ... far more complex than genes, in how they work, and when they work, so that you grow an arm, but only to a point, after which it stops, permanently. (If not, by age 50, your arm would be many times its length.) Thus should it be severed, it will not grow back, unfortunately, and especially no matter how hard you pray to God that it grow back.
But you can pray for a family member or friend with cancer, and have greater success, provided they're also seeking medical treatments and surgery. (as my very, very devout younger brother is, at this very second.) And I believe he will pull through, and that his and his wife's prayers will be answered. (which they will believe, no matter what.)
But they'll be answered by doctors, and not God. Because the world as we've learned is driven by forces in nature, and not divine forces.
But the upside is, we've begun understanding and studying those natural forces, and doctors can intervene in nature, and actually deliver the miracles, which once could only dreamed of, while praying, to something that does not exist.
So thankgod for science, which indeed is improving the lives of humans, and creating the life-saving / -improving miracles we once prayed would become possible.
