British scientists have done it, they've cracked the mystery.
Which came first, the chicken or the egg?
After all this time the mystery may have been solved after discovering that the formation of eggs is possible only because of a protein found in chicken's ovaries.
This means eggs have to be formed in chickens first.
(but where did the first chicken come from?)
The protein -- called ovocledidin-17 (OC-17) -- speeds up the development of the shell. The findings were laid out in the paper "Structural Control of Crystal Nuclei by an Eggshell Protein."
Dr Colin Freeman, from Sheffield University's Department of Engineering Materials, said "it had long been suspected that the egg came first, but now we have the scientific proof that shows that in fact the chicken came first."
