What is ”egg-shaped” even? I used to think it was the shape of a chicken egg. 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!

My guess is that they are harder to be turned, as well as the corners act as greater weakpoints

Next video ideas: 1) why don't we have square heads? 2) why isn't the earth square? 3) why is this channel still called "it's okay to be smart"?

Squares are more difficult to extrude. Curved passages with soft sides favour the safe delivery of life forms enclosed in rounded shells. It's a girl thing, you m#ro#

Eggvolution isn't the most eggxact science. However at times can be eggciting eggspecially when they hatch! It's pretty eggxcellent if I do say so myself

Try damp for moist. Eggs shells are strong. I went out to gather the cackle berries from my hens yesterday, then came in to take a nap, forgetting I had an egg in my pocket (where I put them when I gather them to keep my hands free). I took a nap and discovered an UNbroken egg. It's not the first time I've forgotten I've had eggs in my pocket and discovered them hours later without them being broken. Strong thangs eggs. Your yolks ain't very punny. haha

I just figured it would be because laying a cube, even a small one, with nice round edges, sounds pretty damn uncomfortable.
