That's the beauty of evolution theory, none of the hypothesis they dream up needs to be proven,and it doesn't matter if it clashes with all other hypothesis.
Someone caught a wierd looking fish with human-like teeth the other day. Just wait- it's only a matter of time before a "hypothesis" develops of this previously unknown fish species being the missing link.
The fish was a well-known South American species related to the piranha called a pacu. Its teeth are an evolutionary adaptation for crushing seeds.
How simple and easy - no thought required!
Why don't we do the same with ALL sciences? Why bother studying astronomy? Let's just say everything revolves around the Earth - then we don't have to worry about pesky things like scientific research.
Why bother studying medicine? If someone gets sick, we can just say: "It's God's will".
See how easy life could be?
