text: 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??
