Vulcan ears: On this list of ten vestigial structures still found in the human body appears a former ear design, slightly pointed at the top to focus sound. I'm not sure why one of the 10.4 percent of the population that the page tells us exhibit this conformation wasn't picked for the photo above. My wife and daughter would both have been candidates.
