The “yolk sac” is actually the site where the first blood cells form. Thus, the embryo does not go through an egg stage and does not get nourished by a yolk like chicks or baby lizards. We get our nourishment through the placenta and we have nothing in common with the lower animals in this respect.

  • The “yolk sac” is actually the site where the first blood cells form. Thus, the embryo does not go through an egg stage and does not get nourished by a yolk like chicks or baby lizards. We get our nourishment through the placenta and we have nothing in common with the lower animals in this respect.
  • The human embryo does not recapitulate an imaginary, evolutionary past. It is just as different from other creatures in the one-celled stage as it is when fully grown. Superficially, the zygote looks like a one-celled organism, but that’s because it has not yet divided. Its DNA is different from all other organisms. Only a small part of the human genome has been mapped by geneticists. Depending on which protein is compared, we are more closely related to a bacterium than an ape and vice versa. It becomes a game we can play. If you find a human protein that is almost a 100% match with an ape, someone else can find a protein that relates us more closely to an entirely different organism.

Conclusion

  • What should you remember about vestigial organs? Remember that every organ once considered to be a useless, degenerating leftover from some bygone evolutionary era has important functions in our bodies. It was ignorance that permitted evolutionists to call them vestigial. While the theory of evolution would predict the development of new structures in evolving organisms and possibly the degeneration of no longer needed organs, as our knowledge increases there seems to be little evidence to support these predictions. Indeed, evolution cannot distinguish between developing and degenerating structures, making it a poor theory. A good example of this is the wing claws of the baby hoatzin. On a Discovery show, the moderator wondered if these claws were new developments in the hoatzin or evolutionary leftovers. Although evolutionists commonly regard the wing claws of Archaeopteryx to be primitive structures left over from its reptilian ancestry, the evolutionists who produced the material shown on Discovery couldn’t decide about their status in the hoatzin. Why did the hoatzin keep these ancient features for 175 million years? Evolutionists had trouble believing that a well-developed bird would retain such an ancient feature, so they thought maybe these claws were a new development in the hoatzin’s quest for survival.
  • Dr. Shermer also used arguments from homology and embryonic recapitulation as evidence for evolution. If nothing else, most people who believe in evolution hold the homology banner high. In a later issue we’ll look at homology and discover why it fails as evidence for evolution and actually supports creation.

For a long time, the concept of "vestigial organs" appeared frequently in evolutionist literature as "evidence" of evolution. Eventually, it was silently put to rest when this was proved to be invalid. But some evolutionists still believe in it, and from time to time someone will try to advance "vestigial organs" as important evidence of evolution.

  • The notion of "vestigial organs" was first put forward a century ago. As evolutionists would have it, there existed in the bodies of some creatures a number of non-functional organs. These had been inherited from progenitors and had gradually become vestigial from lack of use.
  • The whole assumption is quite unscientific, and is based entirely on insufficient knowledge. These "non-functional organs" were in fact organs whose "functions had not yet been discovered." The best indication of this was the gradual yet substantial decrease in evolutionists' long list of vestigial organs. S. R. Scadding, an evolutionist himself, concurred with this fact in his article "Can vestigial organs constitute evidence for evolution?"

  • Since it is not possible to unambiguously identify useless structures, and since the structure of the argument used is not scientifically valid, I conclude that 'vestigial organs' provide no special evidence for the theory of evolution.312

The list of vestigial organs that was made by the German Anatomist R. Wiedersheim in 1895 included approximately 100 organs, including the appendix and coccyx. As science progressed, it was discovered that all of the organs in Wiedersheim's list in fact had very important functions. For instance, it was discovered that the appendix, which was supposed to be a "vestigial organ," was in fact a lymphoid organ that fought infections in the body. This fact was made clear in 1997:

  • Other bodily organs and tissues-the thymus, liver, spleen, appendix, bone marrow, and small collections of lymphatic tissue such as the tonsils in the throat and Peyer's patch in the small intestine-are also part of the lymphatic system. They too help the body fight infection.313
  • It was also discovered that the tonsils, which were included in the same list of vestigial organs, had a significant role in protecting the throat against infections, particularly until adolescence. It was found that the coccyx at the lower end of the vertebral column supports the bones around the pelvis and is the convergence point of some small muscles and for this reason, it would not be possible to sit comfortably without a coccyx.
