Nugget Of Knowledge :Which Came First: The Chicken or the Egg?


In the summer of 2010, British researchers cracked the eneggma when they discovered that the protein necessary to create the eggshell was fowlnd exclusively in the ovaries of the chicken. So the chicken had to come first, because the eggshell can’t be made without that protein. Where did the chicken come from?

The protein ovocledidin-17 controls the eggshell crystallisation process, and without it, the shell couldn’t form at all. Scientists weren’t just trying to settle a bet between Hawking and some other scientist, either. Understanding what eggshells are made of has some pretty incredible real-world applications, such as strengthening synthetic bones or stopping freaking global warming.
