@mrwolfusa: Which came first, the chicken or the egg? 🐔🥚 People have argued about it for centuries, but evolution gives a pretty clear answer. Eggs are far older than chickens. Animals were laying eggs hundreds of millions of years before the first chicken ever existed. Chickens came from wild jungle birds, changing very slowly over a very long time. Evolution has no exact "day one." But if you had to pick a moment, it's this: a tiny change in the DNA inside one egg. The bird that laid that egg wasn't a chicken. The bird that hatched from it was. 🧬 So the egg came first. It just wasn't a chicken's egg. It was the egg that made the chicken. Bonus fact: a chicken eggshell is built with a protein called OC 17, which helps the shell crystals form. Tiny changes in proteins like this add up over time. Next time someone asks, what's your answer? Tell me in the comments 👇#learnbiologyontiktok #biology #Science #evolution #mrwolfusa
