Why Is Our Brain in Our Head? 🧠
In this episode, Shiying asked us why our brain is in our head and the answer took us back more than 500 million years to some of the earliest animals with a clear front end and back end. It's an interesting question, one which we don't often answer because we think the answer is obvious right up until the moment you actually try to answer it. Grown-ups: we value your feedback.
