Both sexes not needed here

by on March 2, 2012

Who needs males to reproduce?

Not these asexual organisms known as Whip-tail lizards (found in Southwest USA, Mexico, and South America). All these lizards are females. They reproduce by parthenogenesis, that is, the production of offspring without fertilization by a male.

Whip-tails may be the only known exclusively uni-sexual reptiles. It has been found, though, that Komodo dragons have the ability to switch between sexual and asexual behavior in the absence of males. Talk about survival of the species!
