GUEST has a point, (sorry) inasmuchas there is a ST novel about the time that Spock & Dr. McCoy are sent back in time, and since it is in the stoneage (so to speak) Vulcans do not have logic yet. Therefore Spock "mates" with the lovely Marriette Hartley (see thread on spelling faux pas) creating a son. Therefore, we can only surmise that decendants of Spock's son intermingled with some rather short folks, and thus, pointy eared elfen like folks!
