Give me one reason.

I ask anyone out there to give me ONE decent explanation for why humans have a vestigial tail, an appendix we don't use, and a jaw too small for our teeth, without evolution.Tom

You question has already been covered in:
Are human tails an example of macroevolution?I found that using "vestigial" with the search function.For future reference you should supply a topic title in your opening post and perhaps flesh the OP out a bit more than this one. In this case you could have explained your view of why they are there.
