“Fairytale frog: London Zoo breeds bizarre amphibian for the first time”
It could be the opening of a children’s story: in a great forest on a mountaintop lies a tiny lake, and in that tiny lake lives a tiny frog. But this isn’t just any frog. No, this frog is different. Very, very different. It has big webbed feet, no tongue at all, and (here’s where we leave typical children’s book territory) a whole bunch of chromosomes. The vast majority of the world’s animals, including humans, have two sets of chromosomes. But the Lake Oku clawed frog has twelve sets, which is a high number even for chromosome abundant organisms like plants.
