This is cute, but it's also deeply troubling.
I really don't like Darwin worship. It's true that I think he was the greatest scientist who ever lived, but science has moved on since 1859. Modern scientists respect, but do not worship, the past.
There are a couple of other problems with the lyrics. I'm confused about the reference to "theory" as some kind of "abstraction" and I don't like the implication that we go back and read Darwin to refresh our memory about modern evolutionary theory.
I also don't like the simplistic explanation of how real science is done. It's a common myth that publishing a peer-reviewed paper is the only way to do science. There are two things wrong with this mythology. First are the obvious exceptions, Origin of Species being one of them. Second, there's plenty of bad science papers in the peer-reviewed literature. Publishing in the peer-reviewed literature is neither necessary, nor sufficient, as a measure of good science.
