Researchers have discovered seven new species of miniature frog – all from the genus Brachycephalus – living in the Atlantic Rainforest of Brazil. In a fascinating case of geography influencing evolution, each species lives on a separate mountaintop and has evolved a different skin color and texture. Rachel Feltman’s article in The Washington Post has much more detail about the tiny (less than 1 cm long!) frogs and the paper that introduced them to the world.
The frogs are not, of course, actually new. I’m sure they’ve been living peacefully on their mountaintops, minding their own business, for many years until a bunch of scientists came along to discover them. Sorry, little guys. If the tourists start bothering you, band together and use your toxins.
