A few years ago, a British geneticist, a philosopher and a chicken farmer pooled their resources and concluded that the egg came first. The first egg to have the DNA of a chicken would hatch into a chicken, said professor John Brookfield of the University of Nottingham in 2006. Brookfield and Papineau were speaking at the behest of Disney as a promotion for the film Chicken Little. But their theory has been the prevailing one.
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. Scientists have discovered that eggs can only have been laid by chickens, thus solving the puzzle. 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.
