I can't help thinking about the late, great Douglas Adams when reading this (and just about any scientific article). In the first Hitchhiker's Guide to the Galaxy, upon firing the Infinite Improbability Drive while trying to escape two missiles (with nuclear warheads attached), the missiles turned into a very surprised sperm whale and a bowl of petunias. He goes on to describe "what went through the head of the whale", with a long dialog about coming to terms with its life (while shortly having to come to terms with no longer having one). "Curiously enough, the only thing that went through the mind of the bowl of petunias as it fell was 'Oh no, not again'. Many people have speculated that if we knew exactly why the bowl of petunias had thought that we would know a lot more about the nature of the Universe than we do now." Silliness aside, it's fascinating seeing unexpected discoveries like this -- and something like this really does underscore how large the body of knowledge is that "we don't know" about biology, in general.
