Which Came First, The Chicken Or The Egg? ANSWERED. So which came first, the chicken or the egg?
It's an age old question that no one could actually answer.
Because if the chicken came first, then how did that chicken come into existence?
And the same goes for the egg.
If the egg came first then what laid the egg in the first place.
Well this question has finally been answered, but before I tell you the answer, I want you to pause this video, and leave a comment of what you think came first.
I'm going to give you a few seconds to do that....
Okay done it, good,
Stephen Hawking's himself once got into the chicken or egg debate and his answer was the egg.
Even ancient philosophers like Aristotle were stumped by the question.
His conclusion was the that the chicken and egg must have just always existed.
The theory of evolution would state that the egg came first too.
You see since DNA can only be modified before birth, this would mean a mutation must have taken place at conception.
So some kind of animal similar to a chicken would of laid an egg and a mutated version of that animal would of hatched which would of then been a chicken.
This new chicken would then go on and breed and spread its mutation and more chickens would appear as generations go on.
So a lot of the evidence would point that the egg would of come first.
But these are all theories.
The true answer to this questions lies in protein.
British researchers discovered something very interesting when looking at eggshells.
They noticed that the protein necessary to create eggshells are only found in the ovaries of a chicken.
This means the chicken must have come first.
The protein is called Ovocleidin-17 and it controls the eggshells crystallization process.
Without this protein the shell just couldn't form at all.
You might think the chicken or egg question is ultimately stupid but discovering its answer is actually pretty beneficial.
Knowing what eggshells are made of has some pretty incredible real-world applications, such as strengthening synthetic bones.
Scientists are even coming up with ideas to lower our CO2 problem.
By understanding the protein that makes eggshells form can help us crystallize carbon dioxide into limestone.
If done on a large scale this can actually reverse the whole climate change issues.
So answering the chicken and egg question can actually indirectly save the planet.
Now that we have established that the chicken did come before the egg, what about all the other animals that lay eggs.
Well if we go back into a chickens ancestry we end up with dinosaurs.
In fact we actually end up with the same group of dinosaurs that T-Rex was in.
And if we go back even further we literally end up with micro organisms.
So the real question isn't whether the chicken or egg came first but rather animals or eggs.
