Human Embryology: When Life Begins

From a medical textbook, on when life begins.

“Although human life is a continuous process, fertilization is a critical landmark because, under ordinary circumstances, a new, genetically distinct human organism is thereby formed. … The combination of 23 chromosomes present in each pronucleus results in 46 chromosomes in the zygote. Thus the diploid number is restored and the embryonic genome is formed. The embryo now exists as a genetic unity.”

(O’Rahilly, Ronan and Müller, Fabiola. Human Embryology and Teratology, 2nd edition. New York: Wiley-Liss, 1996, pp. 8, 29).

Did you know that there are hundreds of embryology, genetics and anatomy textbooks that state that life begins at conception? go here to read what textbooks and scientists have to say.
