I think evolution theory is crap. If it really is true, why dont we see monkeys turning into human anytime?

According to Darwin, humans evolve from apes then there must be some apes turning into human after so long right? The theory wont just stop after human exists

Organisms are what they are because of their genetic code.. How can something grow a tail after 1 million years just because they need to swim??

If you're talking about mutation then its different. The gap in evolution theory is too big
