The debate related to the existence of chickens or eggs that first existed is not new that has emerged in recent years, but for a long time, this question has been a debate both among ordinary people and scientists.

Often considered a trivial question, it turns out to answer it is not easy. Until finally scientists succeeded in conducting in-depth studies and succeeded in expressing answers related to this question.

Chicken or Egg, Which Came First?

Based on the results of the research conducted, it was concluded that chickens exist before eggs. Although some sources claim this answer has been officially patented, but the fact this is still causing debate for scientists. Here’s the explanation.

Protein Compounds That Make up Eggshells Are Only Found in Chicken Ovaries

Reporting from, British scientists succeeded in revealing a protein called ovocledidin-17 (OC-17) which is a protein contained in the eggshell that functions in accelerating the formation of eggshells. This protein is only found in chicken ovaries. In the formation of eggshells, calcium is needed which then forms the calcium carbonate crystal (CaCO3) which is then accelerated by the protein. So scientists think that chickens must have been present before eggs.

Not All Scientists Believe the Ovocledidin-17 (OC-17)

Despite the facts that have been presented, there are still many thinkers who disagree with the theory, they believe eggs exist first than chickens. This is based on the theory of evolution. Reporting from, the first eggs were found around 370-340 million years ago, while the first chickens only evolved around 58 thousand years ago, so it can be said that eggs were earlier than chickens.

“Eggs certainly came before chickens, but chicken eggs did not — you can’t have one without the other. However, if we absolutely have to pick a side, based on the evolutionary evidence, we’re on Team Egg. “
