Q. Do you know the answer to the age-old puzzle ‘Who came first; egg or chicken?
Ans. It has been a matter of discussion for ages that who came first, an egg or a chicken. But after long years of mystery and research now the scientists have come to a conclusion that the chicken came first and not the egg. The scientific research has revealed that the protein named ovocledidin-17 that is essential for the formation of egg shells is found in a chicken's ovary. This protein coverts the calcium carbonate into calcite crystals which makes up the egg shell.
