Which came first chicken or the egg ? Scientists have the answer!

It is an age-old riddle that has perplexed generations: Which came first, the chicken or the egg?

Now British scientists claim to have finally come up with the definitive answer: The chicken.

The scientific and philosophical mystery was purportedly unraveled by researchers at Sheffield and Warwick universities, according to the Daily Mail newspaper.

The scientists found that a protein found only in a chicken's ovaries is necessary for the formation of the egg, according to the paper . The egg can therefore only exist if it has been created inside a chicken.

The discovery was revealed in the paper Structural Control Of Crystal Nuclei By An Eggshell Protein.
