Yes, it's another "Which came first, the chicken or the egg?" discussion...
Perhaps we could debate to finally settle this ancient question once and for all?
Eggs were around long,
long before the first chicken (domestic or otherwise). Dinosaurs laid eggs, for example. And I'm guessing so did all the bird ancestors of the first chickens.
I suppose the real question, then, is: Which came first, the chicken or the
chicken egg? (That old question is not usually
phrased like that, is it?) Even after narrowing it down like that, it's obviously a loaded question.
But... if one were to assume, for the sake of argument, that chickens came before chicken eggs, then that implies that the
first chicken did not achieve full chicken status until
after it hatched.
Proto-Chicken has unlocked a new achievement!
Proto-Chicken has earned a new rank.
Proto-Chicken now ranks as "Chicken".
Congrats to Chicken!Another words, it implies that the egg out of which "first chicken" hatched was
not a "chicken egg", but rather would be best categorized as merely another "proto-chicken egg". And
that implies that when
first chicken hatched it underwent a magical metamorphosis to spontaneously
evolve from proto-chicken to full chicken status.
Thing is, scientists claim that Darwinian evolution takes place between generations - during conception. When an egg is fertilized, before it starts the process of cell division, DNA from both parents are mixed. And because this is sexual reproduction, the chance of a random mutation is much higher than with asexual reproduction or
parthenogenesis. Anyway, evolution theory postulates that it is a combination of random mutations and natural selection of the fittest which can eventually (very gradually) give rise to a new species. And since this random mutation takes place during the fertilization of the egg...
Then the question becomes: Could this "first chicken" still have been called a "chicken" immediately after fertilization of the egg, but
before cell division started? If not, then I'd say that the first chicken egg came before the first chicken!
Of course, there's also the question: If the chicken species had not been given the name "chicken" yet and there was nobody around to witness this monumental achievement, could that first chicken be called a chicken at all?
(When a tree falls in the forest and nobody is around to hear it, does it still make a sound?)
