"British scientists believe they have cracked the answer to the age-old question of which came first, the chicken or the egg?
Researchers have found that a protein called ovocleidin (OC-17) is crucial in the formulation of eggshells, and it is produced in the pregnant hen's ovaries, the Daily Express reports."
As the article 'Chicken or egg' question finally answered points out, scientists have established that a chicken's body chemestry is necessary for the formation of eggs. Therefore it is clear that chickens had to have come first. Whew, finally I can scratch that off my list of mysteries to ponder.
Still, I expect there will many Egg-Firster zealots who refuse to admit the truth. Lord knows, they've always been a deluded lot. We can only hope they don't turn violent when they hear the news.
