This episode was especially emotional for me. When I was just a child, my grandfather told me he knew how to draw an egg using a ruler and compass. Unfortunately I never asked him how this could be done, but that question never left my mind. My grandpa would have a birthday this month if he were alive. In a way, I feel good about imagining that maybe this was the solution, and that I no longer need to carry with me the anguish of never having asked what the method was.

Eggs don't have flat spots, so it can't take any longer than that. When we make it ourselves, we bubble CO2 through calcium hydroxide, but that path isn't remotely viable because there isn't enough CO2 in the air, and calcium hydroxide is not great for most living things.

The shape of a bird's egg is evolutionarily influenced by how precariously the species' nests are built. A sphere is the topologically ideal shape for an egg, but it can also easily roll away. An egg shape rolls in a circle, and the "pointier" it is, the smaller the circle. Accordingly, birds that nest on the ground tend to have eggs that are close to spheres, while cliff-dwelling seabirds have extremely pointed eggs that reduce the odds of them rolling off the ledge and plummeting to their doom.

Pointy eggs are less likely to roll down slopes too, and the blunt end, where the chick develops, stays cleaner than the pointy end. It seems to be a combination of all three things.
@finndriver1063

This isn't true, but it's a common myth. Egg shape correlates with the ability to fly. In general, the 'better' a bird species is at flying, the pointier it's eggs are. This is thought to be a side-effect of evolving a more streamlined body. Penguins are the only obvious exception, as they don't fly but most species lay pointed eggs. They do need to be streamlined to swim, however.
@alouped
2 жыл бұрын
@@finndriver1063 "Egg shape correlates with the ability to fly" seems to be the factor in both explanations. Both body shape and tendency to have nests over ground will correlate with a birds ability to fly. But we can't know for sure what exactly was the evolutionary cause, maybe something else entirely.

I agree, if you pause at 4:39 you will be able to notice the curves are close but not an exact match. We have the technology to 3d laser scan thousands of real eggs to compare them to mathematical models. I also doubt that a physical object will have 1 radius of curvature, and then hit a line where it has half the curvature projected around a rotated axis followed by a spherical endcap.

@Nacho Rodríguez No, it is an urban myth. In fact, the shell being made is roughly equivalent to someone's water breaking, it is kinda the final signal to go lay. Further evidence is the fact when you dissolve the shell, the membrane that remains is still egg shaped, because the shape gets set internally. If it was naturally spherical (and somehow coated in some wild, rapid precursor to calcium carbonate that somehow works before the egg can travel the 2 cm to the ground, since eggs don't have flat spots) the shell would be holding it in tension that would be removed, returning the egg to a ball.
