Ce a fost mai întâi, găina sau oul? Oamenii de știință au în sfârșit răspunsul care este uluitor • Newsweek România

The age-old question of whether the chicken or the egg came first has been answered by scientists, revealing that eggs predate chickens. This debate, dating back to ancient Greece, highlights the evolutionary history of egg-laying animals, which existed long before birds. The domestic chicken, a product of gradual evolution, emerged from a genetic combination found in an egg laid by two non-chickens. Eggs have a much older evolutionary legacy, with reptiles and fish laying eggs millions of years before the first chicken appeared. Modern biology confirms that the molecular systems for embryo formation existed in primitive organisms, making the egg a fundamental aspect of life long before birds evolved. Thus, the scientific answer is clear: the egg came first, representing a deep-rooted legacy in the history of life.
