We all have been trying to solve a puzzle since our childhood. Yet it has been so many years and even today the mystery of which came first; egg or chicken, is unsolved. This question has always confused everyone and made people think about it every time. Scientists have finally found an answer to this. In order to find this answer, Professor Sheffield and University of Warwick of UK's Research Institute did a close study on this topic and gave the answer with a reason.

Scientists said that the Chicken came before the Egg, and the biggest thing is that eggs cannot be born without Chicken. In research, it was found that a protein called ovocleidin is found in the egg shield and without this protein the shield is not formed. This protein is made only in the uterus of the hen and until this protein is not used in the uterus, the egg will not be formed. Hence the answer is proved that the chicken came before the egg.

Research revealed that the chicken came first and only then a protein called ovocleidin was made in its uterus and the process of egg formation would start in the hen's womb. Dr Colin Freeman, the lead researcher of this research, said that "This question used to confuse people for a long time, but now everyone knows what the right answer is. The chicken came first".
