Forgive me if this is in the wrong area or if it is a repeated question, but I really want to know the answer. I saw on my local news today that they finally solved the age-old mystery. Apparently, the chicken came first. They didn't explain why, and when I tried to look it up I found tons of articles that said the egg came first.

So is this mystery really solved? Was it really the chicken that came first? And if so, why?

In my opinion, it makes more sense that the egg came first. Two genes from two species could have combined to form a new species, the chicken. And that chicken came from the egg.
