Why are two heads of eggs big and small?

You are interested in exploring? You can also a people who like cooking? So when are you curious, why do the eggs have an . egg shape?

First, observe a chicken egg. Just like the eggs of some reptiles, it does not carry a circle or a sphere but an asymmetrical combination of oval and cone, with a large head and a smaller head.

If they are like small rectangular boxes, the four corners of the egg will be very hard while the surfaces are quite weak and fragile. This is not to mention that this will make it difficult for mother and chicken to give birth.

The shape of the egg is an asymmetrical combination of oval and cone.

The most reasonable shape can only be a ball or sphere. But if so, a very light thrust is enough to make them roll away. However, that phenomenon will not happen with asymmetric oval because when moving, they will rotate in a circle around the point of the tip.

In fact, the eggs of birds nesting on cliffs are often more pronounced oval than those on the ground, limiting the risk of falling from the nest or cliff (because only rolling in small circles).

Moreover, the egg-shaped structure as we still see is quite suitable in the small space of the nest, so that the temperature will be radiated evenly.

In addition, chicken eggs with a sharp tapered head are the ideal shape to help the tubular vagina in the hens body be easily ejected.

Recently, Dr. Lopez-Martinez and colleagues Vicens from the University of Madrid and Barcelona conducted a study of 70 million-year-old eggs found in the Pyrenees. Compared to today's bird eggs, they find that they tend to be longer, rounder and more symmetrical. These characteristics make scientists come to the conclusion that it is fossil dinosaur eggs.
