Post by Ray FischerPost by Warnock***** Yes, human life starts with the combination of the two!
Which is why sperm and egg are dead before fertilization.
***** Strange, my biology teacher did not tell me they were dead!
Then I guess that human life does NOT start at fertilization since the
sperm and egg must be alive before fertilization.
Typical pro-choice retard.

The Developing Human: Clinically Oriented Embryology4 (pp 2-18):
"Zygote: this cell results from the union of an oocyte and a sperm. A
zygote is the beginning of a new human being (i.e., an embryo). Human
development begins at fertilization, the process during which a male
gamete or sperm ... unites with a female gamete or oocyte ... to form
a single cell called a zygote. This highly specialized, totipotent
cell marks the beginning of each of us as a unique individual."

Oriented Embryology (6th ed.), W.B. Saunders Company, Philadelphia.

Essentials of Human Embryology (pp. 1-17): "In this text, we begin our
description of the developing human with the formation and
differentiation of the male and female sex cells or gametes, which
will unite at fertilization to initiate the embryonic development of a
new individual. ... Fertilization takes place in the oviduct ...
resulting in the formation of a zygote containing a single diploid
nucleus. Embryonic development is considered to begin at this point...
This moment of zygote formation may be taken as the beginning or zero
time point of embryonic development."

Human Embryology & Teratology (pp. 5-55): "Fertilization is an
important landmark because, under ordinary circumstances, a new,
genetically distinct human organism is thereby formed... Fertilization
is the procession of events that begins when a spermatozoon makes
contact with a secondary oocyte or its investments... The zygote ...
is a unicellular embryo... "The ill-defined and inaccurate term
pre-embryo, which includes the embryonic disc, is said either to end
with the appearance of the primitive streak or ... to include
neurulation. The term is not used in this book." (p. 55)."

When Does Human Life Begin?
(http://www.californiaprolife.org/abortion/whendoes.html)
"To accept the fact that, after fertilization has taken place, a new
human has come into being is no longer a matter of taste or of
opinion. The human nature of the human being from conception to old
age is not a metaphysical contention. It is plain experimental
evidence."
- Jerome L. LeJeune, French geneticist
