Who came up with the first egg or chicken?

The chicken-egg dilemma has been on people’s heads for a long time, but the answer has finally been found. If we turn to science, or rather to biology and logic, then the solution to the problem will become clear: a chicken is a separate genus of birds (chickens) or a separate species (domestic chicken or another breed). They appeared relatively recently, and the eggs themselves, as a method of reproduction, were used by living organisms long before the appearance of the first birds, for example, dinosaurs or other reptiles. The ancestors of birds also bred with eggs, but they were not yet chickens. It turns out that the egg appeared first. But if the dilemma is not an ordinary egg, but a chicken one, then the first to appear is the chicken that was able to give the chicken egg.
