An 'egg'splanation Poem by Ima Ryma

The chicken or egg - which came first?
This question has been long around,
Over which debate has conversed
With many theories to abound.
One popular theory does be
That the chicken descended from
The dinosaur technically,
And over eons did become
A bird instead of a reptile.
The dinosaur became extinct
And only a memory, while
The chicken evolved, dino linked.

So eggs before chickens were made,
Cuz eggs were what dinosaurs laid.
