The span of the test doesn't mean its not something we can't watch, record, and learn from. This is why some things are theories. This is why we have the theory of
gravity but at the same time Newton's
law. Not because certain concepts don't follow the scientific method of understanding, but because we as humans, don't kid ourselves into thinking we have the complete and full picture about all things.
We do run tests for evolution, we've already had a thread where we watched how
44,000 generations of an organism evolved under controlled scenarios. In fact the monkey response was the same response that DBZ middle schooler gave the CC back then. Step up your game.
