Sun News Desk: The question arises in the mind of many, the egg comes first or the chicken first. However, a group of British researchers recently claimed that the chicken came first. Researchers from the University of Sheffield and Warwick in the UK have studied this for a long time.
Researchers claim that a protein called ovoclidine (also known as OC-17) in the egg white plays an important role in egg formation. This protein is found in the uterus of chickens. This proves that the chicken came first. Then the ovoclidin protein is produced in her uterus and later the egg is formed from it.
