Existing chickens or existing eggs? Is it an existing chicken, or an existing egg

First there were chickens. The egg problem has embroiled countless scientists and science enthusiasts, but according to the British Daily Mail, scientists have experimentally proved that chickens come before eggs, and this is based on the fact that the dependent substance that forms eggshells is a protein that can only be found in the ovaries of chickens.

In other words, there must be a chicken before an egg can be formed.

Scientists from the universities of Sheffield and Warwick used a supercomputer called Hector to zoom in to see how an egg formed. Scientists have observed that a protein called ovocledidin-17 (OC-17) is a key element in initiating the crystallization process of eggshells, which is the initial stage of eggshell formation, and OC-17 converts calcium carbonate into calcite crystals, which in turn make up eggshells.

In the past, scientists generally explained the egg problem from an evolutionary point of view, and it was generally believed that there were two chicken-like species ooxx, and then an egg was made, and this egg hatched the first chicken, so the egg preceded the chicken.

This question does not compound logic, there is no egg without chickens, and there are no chickens without eggs. I also ask you, do you say that there was a man or a woman first. In fact, the nature of these two problems is the same. There is no dead answer.

There were chickens first, and chickens evolved from other animals.

There are chickens first, and other evolutions can be different animals, and this egg can only hatch.

Chickens evolved from other animals, so I think there should be chickens first, and then eggs.

There is no chicken and no egg, to say that it is a chicken is a chicken, to say that it is an egg is to be an egg, why is 1 in front of 2, 123456, can not be 213456

The key to solving the problem is how we define the "egg" -- if we think that the "egg" must be the egg laid by the chicken, then it must be the chicken that came first.

First there were chickens, because the eggs floated out.

The key to solving the problem lies in how we define "eggs" If we think that "eggs" must be eggs laid by chickens, then it must be the first chicken.

I think it's an argument question, and there is a rhetorical argument for either answer.

The existing eggs then evolve into eggs!

Of course, there were chickens first, and other animals evolved into chickens, which were not egg-laying chickens in the first place, and chickens only laid eggs after they evolved.

Once upon a time, there was the question of whether the chicken or the egg came first. The two argued endlessly and refused to give in to each other. The two people turned to the sage for help, and the sage replied: To tell the truth, I don't know. This is: what is known is known, and what is not known is not known.
