text: what organism has an unusual way of regenerating?   some species of the whiptail lizard reproducing without having sex - not completely unusual in nature, but it is for more complex vertebrates. all of the lizards are females and courtship is still required - pairs are formed, one playing the role of the male, the other female, even though no copulation takes place. then they switch places. baby lizards are born through a process known as 'virgin birth'. i think that is pretty interesting - and whoever said homosexuality is not natural??
