Did you see the headlines earlier this year suggesting that a round stingray at a North Carolina aquarium may have become pregnant by one of the male sharks in her tank? As cool as the idea may sound, it is impossible. Sharks and stingrays are somewhat related (about as close as a human is to a mouse), but about 300 million years of evolution separate the species. Genetically, they’re too different to reproduce successfully. But the reality of what probably did happen is just as cool: it’s possible that Charlotte, the solo stingray, cloned herself.
