Thank you bean pods

[Shaun @ Tru6]

New post-asteroid (sorry dinosaurs) fossils have been found and it turns out mammals grew significantly larger with the help of proteins in newly developed bead pods.

"Because of these new protein-rich food sources, mammals, our early ancestors, are now growing a hundred times bigger than the rat-sized survivors of the mass extinction. Some now are as big as wolves. And we won’t see this kind of evolutionary size jump in mammals for another 30 million years."

Likely mammals would not have survived the asteroid strike if they had been larger. Small animals require less food to live. The can hide in tiny areas. Mice and rats have been a scourge of humans through all of history of farming. Humans try hard to eliminate mice and rats and have no real success.

So the bean pods that were a good source of food came along at just the right time.
