The knowledge of our couch of finely-honed scientific minds didn't pop out of the ground fully-formed - it had to be planted, tended, and grown lovingly over a long period of time to flower into the beautiful curiosity tree it is today. But like so much of life, it started as just a tiny, humble seed - which is super convenient for the topic of this episode!
