just-so stories, and name of article
::::If it takes energy and there is a gain in efficiency to be had by its removal, then that should occur unless perhaps the structure is microscopic in size. Based upon your assertion that it should have no affect, then there would likewise be no reason for vestigial structures to become smaller in size, and yet evolutionary theory says that is exactly what has occurred. I should probably also point out that the article as written misses much of current evolutionary thought. While initial beliefs by evolutionists mirrored more of the idea that vestigial structures were useless, that line of thought caused evolutionists to get egg on their face and it is now generally accepted that vestigial structures can provided secondary or alternative positive influences that benefit the species. Vestigial structures are now viewed as those that have lost their original purpose, but without any claim being made to their uselessness.

:::::I think Learn together makes a good point about the resources required, and the response to that just goes to show how flexible evolution is: if evolution gets rid of something, it is because it was a disadvantage, but if it doesn't get rid of something, it must be because it wasn't that much of a disadvantage. It's a tautology, really (how do you know if it was a disadvantage? By whether or not evolution got rid if it), and by being so flexible that it explains everything, it really explains nothing, but is a "just-so" story. [[User:Philip J. Rayment|Philip J.

== Article name ==
I've normally heard of these things as vestigial ''organs'', not ''structures''. I'd vote to change the page name accordingly. Any objections? [[User:Philip J. Rayment|Philip J. Rayment]] 08:00, 28 May 2007 (EDT)
