How many times throughout your life have you heard/made reference to this question? I came across an article at NYDailyNews.com that offers an answer from scientists in England who claim to have solved the mystery.
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.I am so relieved. I've always suspected it was the chicken, but I was just getting my information from God.
21 And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that [it was] good.
22 And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth.
