Some Slithery Ladies Get Pregnant Without Ever Having Sex

Imagine if you got pregnant a couple of years after having sex with a dude? Imagine if you got pregnant without ever having sex?

Even crazier, a female copperhead snake that had been on exhibit — without a mate — for years at the North Carolina Aquarium suddenly gave birth to four “normal-looking” offspring. Mate-less reproduction is called parthenogenesis. And it’s real. Virgin births: Not just for the Bible!
