Cloned horses are galloping their way toward the Olympic Games. The organization that presides over international equestrian events has reversed its position on prohibiting cloned horses from participating in competitions. The Fédération Equestre Internationale in Lausanne, Switzerland, announced their decision in June following a meeting in which up-to-date information on cloning was presented to the federation. Federation members then held a debate, after which it was decided that, for equestrian, cloned horses do not have a clear competitive advantage over non-cloned horses. Because the ruling is so recent, cloned horses do not number amongst the competition at the London Games. But we’re sure to see them at future Olympic Games. The ruling also raises a broader question: how will cloning impact animals in other sports as well?
