Or another poet of the same name in the comedy of errors
We also inherit — through genes yet to be identified, of course — a trait known as developmental stability. This is essentially the accuracy with which the genetic blueprint is built. Developmental stability keeps the project on track. It reveals itself most obviously in physical symmetry. The two sides of our bodies and brains are constructed separately but from the same 23,000-gene blueprint. If you have high developmental stability, you’ll turn out highly symmetrical. Your feet will be the same shoe size, and the two sides of your face will be identical.
If you’re less developmentally stable, you’ll have feet up to a half-size different and a face that’s like two faces fused together.
