"scientist" who just figured that out ought to turn in his union card.
So what you're saying is that question should have been: which came
first, the lizard (or fish) or the egg? 🙂
Well, technically, the "egg" goes back to our days as single-celled
organisms (bacteria, et al).
Since then there have been refinements, such as eggs that could become
multi-celled organisms*
I think the semantic hair the panel split was that it's not a chicken
until the thing coming out is a chicken, and before that it's something
else. And the determination is that the parents of the first chicken
weren't chickens, genetically speaking.

* - isn't it fascinating: this single cell laid by the hen, all within
itself, merely reorganizes its molecules, never gaining anything but
maybe some transferred gases and heat, and becomes a living, breathing
thing... This of all facts makes me feel a little guilty eating an
egg, when I would never feel guilty eating a chicken. I guess I regard
that process as more elegant and wondrous than its result.
