It's a question that has plagued man for centuries: Which came first, the chicken or the egg?
Well, scientists in England say they've found the answer: The chicken!
Researchers wrote in a recently published report that it all comes down to one protein - ovocledidin-17 - which helps in the formation of the egg's hard shell.
This essential ingredient in the formation of the egg can only be produced inside a chicken, scientists from universities in Sheffield and Warwick concluded.
Now we can all breath a little easier and concentrate on less weighty matters.
