Vestigial Organs

Some structures in humans were once thought to have no function but to
have been derived from functioning organs in claimed evolutionary
ancestors (a). They were called vestigial organs. As medical knowledge
has increased, at least some function has been discovered for all
alleged vestigial organs (b). For example, the human appendix was once
considered a useless remnant from our evolutionary past. The appendix
seems to play a role in antibody production and protects part of the
intestine from infections and tumor growths (c). Indeed, the absence
of true vestigial organs implies evolution never happened.

a.    “The existence of functionless ‘vestigial organs’ was presented by
Darwin, and is often cited by current biology textbooks, as part of
the evidence for evolution. ... An analysis of the difficulties in
unambiguously identifying functionless structures and an analysis of
the nature of the argument, leads to the conclusion that ‘vestigial
organs’ provide no evidence for evolutionary theory.” S. R. Scadding,
“Do ‘Vestigial Organs’ Provide Evidence for Evolution?” Evolutionary
Theory, Vol. 5, No. 3, May 1981, p. 173.

b.    Jerry Bergman and George Howe, “Vestigial Organs” Are Fully
Functional (Terre Haute, Indiana: Creation Research Society Books,
1990).

c.    “The appendix is not generally credited with substantial function.
However, current evidence tends to involve it in the immunologic
mechanism.” Gordon McHardy, “The Appendix,” Gastroenterology, Vol. 4,
editor J. Edward Berk (Philadelphia: W. B. Saunders Co., 1985), p.
2609.

“Thus, although scientists have long discounted the human appendix as
a vestigial organ, a growing quantity of evidence indicates that the
appendix does in fact have a significant function as a part of the
body’s immune system.”  N. Roberts, “Does the Appendix Serve a Purpose
in Any Animal?” Scientific American, Vol. 285, November 2001, p. 96.
