The Three Forms of Human Life
There are three forms of human life: (1) The Human Adult (The Born Human);
(2) The Human Gamete (The Human Egg/Human Sperm); (3) The Human Zygote (The
Human Fetus, The Unborn Human)
The True Facts of Human Life: Early Life Forms -> Human Life Forms ->
Human Parents -> Human Gametes -> Human Zygotes.
Adult = Born Individual = Individual capable of producing gametes necessary
under normal/non-cloning reproductive conditions.
Gamete = Egg or Sperm = Reproductive cells necessary for reproduction under
Zygote = Fertilized Gamete = Fertilized egg, a fetus, an unborn individual.
Note: -> = Symbol designating 'evolves into, develops into, becomes,'
Restated: From early life forms human life forms develop/evolve, which include
human parents who produce human gametes which when fertilized conceive and
produce human zygotes.
Life began a long time ago, when the first life forms evolved from non-life
Life continued from those early life forms to the present life forms.
Those of us alive today are direct descendants of the first life forms;
we could not be here if there had been a break in the chain of our causality
via evolution from the first life forms.
The first life forms were adults capable of reproducing, first by cell division,
later through sexual union.
Thus, the answer to "Which came first--the chicken or the egg?!?!?!" is
Restated: If "chicken" = adult/born/hatched/etc. life form and "egg" = unborn/unhatched/etc.
life form, then, on the premise that the adult/born/hatched/etc. must come
before the unborn/unatched/etc., the chicken/adult/born/hatched/etc. came
before the egg/unborn/unhatched/etc.
What has been omitted from this famous question are the gametes.
If the question "Which came first--the chicken or the egg?!?!?!" is reworded
"Which came first--the chicken or the chicken's gametes?!?!?!" or "Which came
first--the chicken, the chicken's gametes, or the chicken's zygote(s)?!?!?!",
One of the biological characteristics of human skin cells, cancer cells,
reproductive cells/gametes, zygotes, and adults, is the presence of DNA which
is uniquely human.
Thus, biologically, to be "human" is to have--be biologically based upon--human
Inre human reproduction, the human reproductive cells known as gametes have
human DNA; human adults and human zygotes likewise have human DNA.
