Oldest "Chicken Or Egg" Mystry Question Already answered "Which came first, the chicken or the egg?"

"Which came first, the chicken or the egg?" has become the most philosophical and scientific questions for centuries. Now, the answer is already available. Scientists claim to have solved the puzzle. The answer, they say, is chicken.

As reported Mailonline, the researchers found egg shell formation depends a protein that is found only in chicken ovaries. That is, the egg can only exist if it was in the chicken. Protein called ovocledidin-17 (OC-17) acts as a catalyst to accelerate the development of the egg shell.

Hard shell is important as a place for egg yolk and white. Scientists from the universities in Sheffield and Warwick use a super computer to download'zoom in 'the formation of the egg. Hector's computer called OC-17 reveal important in initiating the early stages of crystallization or the creation of the shell.

These proteins change of calcium carbonate into calcite crystals that form eggshells. Calcite crystals in a variety of bone and shell, but they are formed more quickly in the chicken. Poultry was able to produce six grams of egg shells every 24 hours.

"During this time people thought that there is first an egg, but now we have scientific evidence showing the actual chicken is much older then," said Dr Colin Freeman, from the Department of Materials Engineering University of Sheffield said, adding, "Obviously, with us to check them jelly can see how proteins control the process of formation of egg shells. "

Professor John Harding, from the same department in Sheffield, said the findings could be useful for other things. "Understanding how to make a chicken egg shell can provide clues to the new design and new materials," he said. The discovery was published in the paper "Structural Control Of Crystal By An Eggshell Protein"
