9. Whiptail Lizard
This amphibian doesn’t waste any time looking for Mr. Right or even Mr. Right Now — in fact, in this species, there’s no “Mr.” anything! Thanks to evolution, males are nonexistent, but the whiptail lizard ladies have found a way around in vitro. A female will get a surge of testosterone, mimicking male behavior enough to trigger reproduction in another female, who can lay eggs and fertilize herself. How’s that for girl power?
