Which is first ? Egg or chicken....

 The above question was unanswered till now.

But now a group of English scientists have come with several evidences to prove  Chicken has come first  !!! 

Their theory is - - - 

1.  A protein called ovoclaudin is found in egg shell. 

2.  According to the scientists, without this protein egg shell can not be formed. 

3.  Interestingly, this protein can be found only in the uterus of chicken. 

4.  Eggshell plays crucial role in formation of egg. 

5.  From these findings., now we can conclude that 

               CHICKEN CAME FIRST, NOT EGG   !!!! 

But question still remains, 

                       From where does the chicken come   ??!!
