According to the advocates of evolution, many of earth's creatures have within their bodies certain structures which are entirely useless. Reputedly, these body features are the remnants of a former phase of the animal's evolutionary past. Even human beings are supposed to have these physical relics of their evolutionary background.

These buttons have no present function. However, in a bygone era, they served as attachments for lacy shirt sleeves which extended out of, and folded back along, the coat sleeves. Similarly, it is alleged, different creatures, including humans, possess vestigial organs that point to a more primitive existence. Reflect upon this assertion for a moment. First, arguments of this nature are simply groundless speculations born of the desire to find some evidence for evolution.
