Heee! That komodo dragon situation is actually a fairly common method of reproduction in many lizard species. Two sexual species can hybridize together to create an asexual one that can reproduce by parthenogenesis (because they are polyploid, having extra sets of chromosomes). It's been theorized that that may have evolved because of its benefits in colonizing new areas - it only would take one individual to create an entire population. It's fascinating! :)
