Joe, my friend, says that humans actually have a tail! He's wrong, right?

Dear Jimmy:
Nope, your friend's not wrong; he's right! Sorry.... you humans do have a tail -- at least the
remnant of what was once a tail in ancestors hundreds of thousands of years ago.
Your "tail" is a short set of fused bones or vertebrae at the end of your spine. It's called
your coccyx! You can actually feel it at the bottom of your spine.
Signed,
Wendell
