What Came First, The Chicken Or The Egg?
Marilyn responds: Parade .
I think the egg came first. A chicken is not defined by the type of egg it lays. (A horse is a horse even if it gives birth to a mule.) But an egg is defined by the kind of creature it contains. (An egg that contains a robin is a 'robin' egg, no matter what laid it.) Therefore, if you believe in evolution, at some point a creature which was almost a chicken laid an egg that contained a chicken, and as an egg is defined by the kind of creature it contains, the egg came first.
However we aren't chickens are we?
