dysteleology

American Heritage® Dictionary of the English Language, Fourth Edition

1. n. The doctrine of purposelessness in nature.
2. n. Purposelessness in natural structures, as manifested by the existence of vestigial or nonfunctional organs or parts.

Century Dictionary and Cyclopedia

1. n. The science of rudimentary or vestigial organs, apparently functionless or of no use or purpose in the economy of the organism, with reference to the doctrine of purposelessness. The idea is that many useless or even hurtful parts may be present in an organism in obedience to the law of heredity simply, and that such are evidences of the lack of design or purpose or “final cause” which the doctrines of teleology presume.
2. n. Any evasion of the functional aim or end, as where an insect punctures a nectary from below without coming into contact with the anthers, thus frustrating the end of cross-fertilization.
