How tf does the theory of evolution explain internal organs?
How can a complex, functional mechanism be expected to evolve in the process of natural selection?
Wouldn't it take many, many generations until a proto-liver for example was at all functional? Why would this trait of having a semi-liver at all survive? What's advantagous about having some tissue inside that could one day do something for your grand-grand-offspring? Do you survive more with an early liver that doesn't do anything yet or do you get more ladies that way? An early internal organ would surely require multiple random mutations until it did anything at all. And why would these traits survive in the population at all while not yet being useful?
