Is it possible for a female deer to have antlers?

According to this article, http://links.jstor.org/sici?sici=0022-2372(195411)35%3A4%3C486%3AAIFDWA%3E2.0.CO%3B2-4 some female deer do occasionally develop horns. The reason females don't have horns (usually) stems from the fact that males need them to fight with other bucks--usually over other mates, but perhaps over territory. This article explains all of the theories well, despite the really bad jokes: http://www.collegian.psu.edu/archive/2005/12/12-06-05tdc/12-06-05dscihealth-column-01.asp
