What’s the most common egg shape? Why are they shaped that way? And why don’t birds lay cubed eggs? Joe Hanson explores the science behind eggs and their shapes in this puntastic episode of It’s Okay to Be Smart. He explains:

Then one day I saw a collection of eggs from lots of different bird species, and I realized just how many different kind of egg shapes there really are! I had to know why. And it turns out a couple teams of scientists had wondered the same thing. Here’s what science says about why eggs are egg-shaped, if that’s even a thing, which I’ve learned it might not be. Evolution of bird eggs, go!
