What cames first egg or chicken?

The Scientific Answer:

* The egg came first. Chickens evolved from a bird species that didn't lay eggs identical to those of modern chickens. Over time, mutations led to gradual changes, and eventually, a bird laid an egg that contained a chick with the genetic makeup of what we now call a chicken.

The Catch:

* It's a matter of definition. If we define "chicken" as a bird with the specific genetic makeup of a modern chicken, then the first chicken must have hatched from an egg laid by a bird that wasn't quite a chicken yet.

* It's a bit of a semantic trap. The question makes it seem like there's a single, definitive answer. But the evolution of species is a gradual process, not a sudden event.

The Bottom Line:

The question isn't really about a single event but about the process of evolution. The first chicken egg was laid by a bird that was not a chicken, and the first chicken hatched from that egg.
