Vestigial Structures and "Junk" DNA

While preparing a science lesson on animal physiology, this question came to my mind.  Naturalists use the existence of seemingly atrophied or near-useless organs and structures as evidence of physiological transition in an evolutionary timeline.

For example, if you have a vermiform appendix hanging out in your body, not doing much, then it seems to follow that it did serve a purpose long ago that is no longer needed in this stage of human evolution.  I don't believe questions about why emus have wings or whether manatees once had legs are wrong to ask (is this not the purpose of science?), but I think they lead to better answers than evolution.

Did someone say Answers?  Here are some web articles on vestigial structures you might find interesting:

Are there several organs in the human body that have no useful purpose? Are there “badly designed” parts of our body?

What about design features in animals that seem to have no use, such as wings on penguins? Why have evolutionists had such interest in claiming that this supports evolution?

What about “Vestigial” (“junk”) DNA that evolutionists claim is a useless leftover of evolution?

�Junk� DNA Is Not �Junk�
Dr. DeWitt shows how evolutionary assumptions have led to the mistaken belief that DNA is filled with “junk” leftovers from millions of years of evolution. On the contrary, this supposed junk has proven to play many essential roles.
