It's absolutely not. For one, Ponies were stated to have evolved, and she's old enough to have probably watched several species pop up in real time.

This issue isn't approached for a reason.
Besides, speciation is no problem; I don't think any scientific mind for the most part is going to deny natural selection.

I have a theory about how the tourney is gonna go though. If they do it right, Goku gets his shining moment and seals a U7 victory with at least him, Vegeta, and Frieza still in the fight. While Goku is weak from the fight, he gets knocked out by Frieza, who wants the wish, which leaves Vegeta vs Frieza alone, finally the way it was meant to be.

But if there are any players left, U7 will automatically win and the wish goes to the MVP.
