[QUOTE="midnightsun, post: 65209, member: 463"] Same “The egg came first, as eggs existed long before chickens, but the first chicken hatched from an egg laid by a bird that was almost a chicken, making the "chicken egg" (containing a chicken) precede the first adult chicken through a genetic mutation. Evolutionarily, the egg, a reproductive structure, evolved hundreds of millions of years before the specific species Gallus gallus (chicken), which arose much more recently. Evolutionary Explanation Eggs Came First (Generally): Hard-shelled amniotic eggs, allowing reproduction on land, appeared around 312 million years ago, long before birds, let alone chickens, existed. The Proto-Chicken: Chickens evolved from junglefowl. A bird that was not quite a chicken (a "proto-chicken") mated with another proto-chicken. The Genetic Mutation: A genetic mutation occurred in the fertilized egg, resulting in the first animal that could be classified as a modern chicken. The First Chicken: This proto-chicken laid the first egg, which hatched into the first true chicken, meaning the egg containing the first chicken came before the chicken itself. In Summary [LIST] [*]Eggs (in general): Preceded chickens by millions of years. [*]Chicken eggs (containing chickens):The first true chicken hatched from an egg laid by a proto-chicken, so the egg came first in this specific context as well.” [/LIST] [/QUOTE]
