Has there ever been a serious scientific experiment, published in a mainstream journal, that attempted to disprove evolution?

Falsifiability is part of the scientific method, right? If there's never been any real effort to falsify evolution, then it's not a proper scientific theory.

>Falsifiability is part of the scientific method, right?

No.

Why don't you make a paper disproving evolution then?

No?

You've just contradicted yourself. If falsifiability is part of the scientific method, then if nobody has tried to falsify evolution then it means the scientific method is not being observed.

Going around looking for proof that your theory is right, and ignoring any evidence to the contrary, is what they do on the show Ancient Aliens.

It's not a trick of mathematics because in physics and other related sciences you are always looking for a value and solving. In mathematics, it can be arbitrary and you're just looking for a proof that a relationship can be true.
