who came first,the chicken or the egg?
The first cell of any organism is the zygote which is formed by the fusion of male and female gamete. This first cell divides and forms a complete animal. Without that first cell we cannot obtain a whole chicken. If we consider that the first chicken has evolved from two closely related non chicken parents due to mutation, it is important to form the zygote from both the parent’s DNA. We can also consider that before this zygote no chickens were there. As the zygote remains inside egg, egg appears first and then chicken.
