This was news all on its own, as the flatworm is not a species known for its scholastic aptitude. I’m not sure what practical application this has for my life, but it leads me to believe that we really have no clue where our good ideas come from. I’m guessing I felt a little like that flatworm, with just a vague idea of where I ought to be going. I’m not smart enough to be a researcher, and I suspect people will know a lot more about these things after I’m dead, but I sincerely believe in the flatworm principle. But we also have no real understanding of where our good ideas do come from, which, considering how much we’ve studied the brain, is kind of amazing.
