Which came first, the chicken or the egg? This is one of oldest questions and everyone has their own . Now scientists believe they have cracked it and have unscrambled this . Researchers from Sheffield and Warwick Universities in England discovered the by mistake. They used a super computer to zoom in on the shell-making while a new shell was forming. They said it all boils down to one protein called OC17 that is for eggshell. This is only found inside a chicken's ovaries, which is that the chicken came first. The team was looking at how animals and birds make eggshells but suddenly made their surprising . The big question now is where chickens came from. The answer to that is from dinosaurs.

The research team said eggshells are one of most amazing creations. Professor John Harding from Sheffield University told reporters: "Understanding how chickens make eggshells is in itself but can also give towards designing new materials and ." Eggshells are very lightweight but incredibly . The most cutting-edge materials designed by the world’s top engineers cannot anything as brilliant as an eggshell. Professor Harding added that eggshells could help find new answers to bone-healing processes and used by the construction : "Nature has found innovative solutions that work for all kinds of problems in materials and technology -- we can learn a lot from them," he said.
