Which Came First?

The chicken or the egg?

Well, apparently some science nerds in Britain have figured that one out:
It has been the ultimate philosophical and scientific mystery for centuries - until now, that is.

Scientists yesterday claimed to have cracked the riddle of whether the chicken or the egg came first.

The answer, they say, is the chicken. Researchers found that the formation of egg shells relies on a protein found only in a chicken's ovaries.

Therefore, an egg can exist only if it has been inside a chicken.

The protein - called ovocledidin-17, or OC-17 - acts as a catalyst to speed up the development of the shell.

This hard shell is essential to house the yolk and its protective fluids while the chick develops inside.
And in other news, leading physicists have proven beyond a reasonable doubt that the bird is indeed the word.
