Did You Know that Some Lizards Are All Female?

Yesterday evening I watched an interesting magazine on the National Geographic TV channel about strange animal sex life and the war of sexes. The number 1 of the top 10 was a lizard, which doesn’t have a male anymore, they’re all females now, although million of years ago males did exist.

More details about this can be found on the Web and/or Encyclopedia articles such as this one in Britannica Online Encyclopedia:

Parthenogenesis in lizards was first discovered in all-female races of Lacerta in the Caucasus, but it is now known to occur in all-female species of whiptail lizards (Aspidoscelis) in the southwestern United States and parts of Mexico, several other Teiidae and Gymnophthalmidae (spectacled lizards or microteiids) in South America, and a few Gekkonidae.
