SciShow: Your Head Might Be On Sideways

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: In your brain the right side controls the left half of your body and vice versa. We still aren't sure why this is, but some scientists have come up with a pretty bizarre explanation: that some ancient vertebrate ancestor was born with its brain on backwards. Or, at least on sideways. Hosted by: Michael Aranda SciShow has a spinoff podcast! It's called SciShow Tangents.
