Intai a fost oul, nu gaina

A geneticist, a philosopher and a chicken farmer say they have found the answer to a great evolutionary puzzle.
The experts looked at the evidence in the long-standing debate over which came first - the chicken or the egg - and opted for the egg.
Professor John Brookfield, a genetics expert from Nottingham University, said the first chicken must have started out as an embryo in an egg.
This means the organism in the eggshell would have the same DNA as the chicken.
He explained that the reason was due to the fact that genetic material does not change during an animal’s life.
Professor Brookfield said: “The first living thing which we could say unequivocally was a member of the species would be this first egg, so I would conclude that the egg came first.”
Adica, intai a fost oul, dar in niciun caz ou de gaina. Un ou, acolo…
