Which came first, the chicken or the egg?

Imagine a time, thousands of years ago, when there were no chickens yet. Instead, there were two birds that were almost chickens—let’s call them “Proto-Chickens.”

One sunny day, these two Proto-Chickens mated. During the fertilization process, a tiny, happy little accident happened: a genetic mutation (a small change in the DNA).

The mother Proto-Chicken laid an egg.

Because of that tiny mutation, the egg was slightly different from its parents.

Inside that specific egg was the very first actual, real-deal, biological chicken!

This means the very first chicken had to hatch from an egg. Therefore, the egg had to exist before that first chicken could step out into the world and say, “Cluck!”

The “Chicken” Plot Twist (Just for Fun!)

To be completely fair, a group of scientists once found a special protein called OC-17. This protein is absolutely necessary to create a chicken eggshell, and it is only produced inside a chicken’s ovaries.

At first, some people celebrated and said, “Aha! This proves the chicken came first because you need a chicken’s body to make the eggshell!”

However, most biologists shook their heads. They pointed out that even if the specific chemical recipe for a modern chicken eggshell required OC-17, the ancestral bird (the Proto-Chicken) likely had a very similar protein to make its own shells. The evolutionary transition still happened inside an egg.
