Life evolved on Earth and for billions of years it was basically just pond scum. Some of the earliest known multicellular life looked like ravioli.
Things have been stuck as "tetrapod" for so long it's starting to get boring. New body plans? Sometime? Maybe?
Also, the tardigrades keep trying to colonize our planet and it's starting to piss us off.
