Most people know their left from their right, and so do their bodies. But how? In the third and final video in their series on guts, It’s Okay To Be Smart looks at exactly that. This episode delves into the important of symmetry and asymmetry to life, and where those things may have come from in evolution.
The other two videos explain why your brain is in your head and why humans aren’t built like lobsters, and they’re also worth checking out. Come to think of it, so are the rest of the videos from It’s Okay To Be Smart. It’s a really great series.
