Whenever children or the elderly sat in one place and extinguished puzzles, a particular question always made people's minds. Often this question was asked that what comes first the chicken or egg the world? No one could answer this question because if you say egg, then it was asked who produced this egg then? And if you call it a chicken, then it was asked that from what did this chicken come out? In such a situation, this question always kept people confused. But now scientists have found the real and correct answer to this question. This time it has been answered with scientific reasoning. In order to find the answer to this question, many professors of Sheffield and Warwick University in the United Kingdom did research on it. A lot of research has been done on this topic. After long research, scientists have found the right answer for this. According to research, the chicken first came to this world. Scientists told that the chicken came before the egg in the world. There is one most important reason for this. And without this reason, eggs can never be born. Research has revealed that a protein called ovocleidin is found in the shell of the egg. Without it, the eggshell will not be formed. And this protein is made only in the uterus of the chicken. In such a situation, until this protein from the hen's uterus is not used in the manufacture of eggs, the egg will not be formed. Thus it is confirmed that the chicken came before the egg in the world. When the chicken came, then ovocleidin was formed in its uterus and then this protein reached the eggshell. With this, it has been confirmed that before the egg hen came to the world.
