As several people have already pointed out, all mammals have caudal (tail) vertebrae. I just thought I'd relay the reason...
The muscles that move the tail also play a role in defecation. I hope this doesn't sound too "gross," but... When you contract muscles to get that last little bit of fecal matter to drop into the toilet, you're actually flexing and/or extending your tail vertebrae. Therefor, they're actually quite important to us. In addition, these muscles also form what amounts to a "sling" at the base of the pelvis, that for lack of a better way to explain it... hold your organs in under normal conditions. Medical conditions such as uterine prolapse (where the uterus essentially starts to "fall through" the pelvic floor") are the result of failure of these tail muscles.

Apes don't have tails, but they do have tail bones.

Even if you can't see them on the outside (like people for instance) the bones are there.
