🥚🐔 What came first — the chicken or the egg? Scientists have finally answered: the chicken!
Researchers discovered a special protein, ovocleidin-17 (OC-17), which is essential for forming eggshells. This protein turns calcium into a hard shell that protects the yolk — but it is produced only in the hen’s oviduct.
⚡ Conclusion: without the chicken, the modern egg simply could not exist. Of course, eggs have existed in nature before — among reptiles, dinosaurs, and other creatures — but the chicken egg specifically requires the chicken.
Science has once again shed light on a mystery that has puzzled people for centuries.
And what do you think — could the scientists be wrong?
