Life does not begin at conception, we know that for a fact. Even before conception, an egg is human life, so is sperm. What if life begins when God provides a human spirit? When does that happen? Many believe that the Bible indicates that happens when we draw our first breath, I'm not sure I'm totally comfortable with that interpretation either.
Actually, thanks to advancements in science we DO know that a new human being is formed and created and begins its life at conception.
“The life cycle of mammals begins when a sperm enters an egg.” Okada et al., A role for the elongator complex in zygotic paternal genome demethylation, NATURE 463:554 (Jan. 28, 2010)
“Fertilization is the process by which male and female haploid gametes (sperm and egg) unite to produce a genetically distinct individual.”Signorelli et al., Kinases, phosphatases and proteases during sperm capacitation, CELL TISSUE RES. 349(3):765 (Mar. 20, 2012)
“Fertilization – the fusion of gametes to produce a new organism – is the culmination of a multitude of intricately regulated cellular processes.” Marcello et al., Fertilization, ADV. EXP. BIOL. 757:321 (2013)
“Human life begins at fertilization, the process during which a male gamete or sperm (spermatozoo developmentn) unites with a female gamete or oocyte (ovum) to form a single cell called a zygote. This highly specialized, totipotent cell marked the beginning of each of us as a unique individual.” “A zygote is the beginning of a new human being (i.e., an embryo).” Keith L. Moore, The Developing Human: Clinically Oriented Embryology, 7th edition. Philadelphia, PA: Saunders, 2003. pp. 16, 2.
“In that fraction of a second when the chromosomes form pairs, the sex of the new child will be determined, hereditary characteristics received from each parent will be set, and a new life will have begun.” Kaluger, G., and Kaluger, M., Human Development: The Span of Life, page 28-29, The C.V. Mosby Co., St. Louis, 1974
An embryology textbook describes how birth is just an event in the development of a baby, not the beginning of his/her life:
“It should always be remembered that many organs are still not completely developed by full-term and birth should be regarded only as an incident in the whole developmental process.” F Beck Human Embryology, Blackwell Scientific Publications, 1985 page vi
“It is the penetration of the ovum by a sperm and the resulting mingling of nuclear material each brings to the union that constitutes the initiation of the life of a new individual.” Clark Edward and Corliss Patten’s Human Embryology, McGraw – Hill Inc., 30
“Although it is customary to divide human development into prenatal and postnatal periods, it is important to realize that birth is merely a dramatic event during development resulting in a change in environment.” The Developing Human: Clinically Oriented Embryology fifth edition, Moore and Persaud, 1993, Saunders Company, page 1
“The zygote and early embryo are living human organisms.” Keith L. Moore & T.V.N. Persaud Before We Are Born – Essentials of Embryology and Birth Defects (W.B. Saunders Company, 1998. Fifth edition.) Page 500
“Thus a new cell is formed from the union of a male and a female gamete. [sperm and egg cells] The cell, referred to as the zygote, contains a new combination of genetic material, resulting in an individual different from either parent and from anyone else in the world.” Sally B Olds, et al., Obstetric Nursing (Menlo Park, California: Addison – Wesley publishing, 1980) P 136
“The term conception refers to the union of the male and female pronuclear elements of procreation from which a new living being develops. It is synonymous with the terms fecundation, impregnation, and fertilization … The zygote thus formed represents the beginning of a new life.” J.P. Greenhill and E.A. Freidman. Biological Principles and Modern Practice of Obstetrics. Philadelphia: W.B. Saunders Publishers. 1974 Pages 17 and 23.
“[All] organisms, however large and complex they might be as full grown, begin life as a single cell. This is true for the human being, for instance, who begins life as a fertilized ovum.”Dr. Morris Krieger “The Human Reproductive System” p 88 (1969) Sterling Pub. Co
