OMGOSSUM!!!

Fun fact to know and share: Every animal and fish on this planet - you, me, the birds, the frogs, trout, whales, and even the freaky opossum - is but a modification of the original fish vertebrate that is all our direct ancestor way, way back when - two eyes, two arms, two legs, everything's basically the same, just in different configurations.

Proof enough of evolution, for any doubters, I'd think. But then, no amount of proof is enough for some.
