Vestiges can be functional First, and most importantly, this line of argumentation is beside the point, since it is unnecessary for vestiges to lack a function (see Muller 2002 for a modern discussion of the vestigial concept that specifically includes functionality). Many true vestiges are functional (for many examples see Culver et al . 1995 ). In popular usage "vestigial" is often believed to be synonymous with "nonfunctional", and this confusion unfortunately has been propagated via poorly-worded definitions found in many non-technical dictionaries and encyclopedias. Even some professional research biologists have fallen prey to this oversimplification of the vestigial concept (for instance, Scadding 1981 , often quoted by anti-evolutionists and discussed in the Citing Scadding (1981) and Misunderstanding Vestigiality FAQ). The statement that vestigial structures are functionless is a convenient, yet strictly incorrect, approximation. It is analogous to the common, yet strictly incorrect, scientific claim that the earth is a sphere. Several evolution deniers have falsely claimed that biologists changed the definition of vestigial and rudimentary structures when functions were found for many vestiges (see Bergman and Howe 1990 , pp. 2-3; Sarfati, J. 2002 ). For example, Answers in Genesis ' Jonathan Sarfati states: Historical definitions of ' Vestigial ' including functionality See quotes at left from Darwin 1859 and 1872, Weismann 1886, and Wiedersheim 1893. vestigial . a. Of, pertaining to, or of the nature of a vestige; like a mere trace of what has been; also, rudimentary. In biology vestigial has a specific application to those organs or structures which are commonly called rudimentary , and are rudimentary in fact, but which are properly regarded, not as beginnings or incipient states, but as remains of parts or structures which have been better developed in an earlier stage of existence of the same organismm, or in lower preceding organisms, and have aborted or atrophied, or become otherwise reduced or rudimental in the evolution of the individual or of the species. ( The Century Dictionary: An Encyclopedic Lexicon of the English Language 1911) "Vestigial organs are sometimes pressed into a secondary use when their original function has been lost." ( The Story of Evolution , Joseph McCabe , 1912, p.264) vestige b. (biol.) a rudimentary, degenerate survival of a former organ or structure. ( Universal Dictionary of the English Language 1932) vestige n. 2. Biol Specif., a small, degenerate, or imperfectly developed part or organ which has been more fully developed in an earlier stage of the individiual or in a past generation. ( Webster's New International Dictionary of the English Language 1957) When structures undergo a reduction in size together with a loss of their typical function, that is, when they become vestigial, they are quite commonly considered to be degenerate and functionless. But Simpson has recently pointed out that this need not be true at all: the loss of the
