Which Came First: The Chicken or the Egg?

The question of “which came first, the chicken or the egg?” is probably one of the most famous in history. We have all had debates over why the egg came first or why that never would’ve been possible. It’s also likely that you are strongly entrenched on one side or the other. Stephen Hawking, the famous physicist even weighed in on the debate and said it had to be the egg, to which many probably conceited defeat.

This question can be polarizing, but science has determined the definitive correct answer!

Check out the video below or keep reading to find the answer.

In the summer of 2010, British researchers made a breakthrough chicken discovery when they found the protein responsible for creating the eggshell to be exclusive to the ovaries of a female. This the egg could never have formed without this super exclusive chicken ovary protein. So, the chicken came first!

Where then do you say the chicken came from? Science still isn’t sure about that one.

The protein is called ovocledidin-17 and it controls the eggshell crystallization process. Without the presence of this protein, the shell could never form. Researchers didn’t just find this protein to answer the famous question, they actually wanted to discover it so they could make synthetic bone for humans and even stop global warming.

If applied properly, Ovocledidin-17 would allow us to crystallize excess CO2 into limestone solids. This would allow us to capture much of the excess pollution in the world and store it in a solid material rather than letting it be free in the atmosphere.

So, the chicken came before the egg and because science proved that, we might be able to turn excess CO2 into solid blocks of limestone and create synthetic bone. Who knew this famous question had so many implications.
