What Science Tells Us

The Colorado Personhood Amendment has a very simple, easy-to-understand scientific basis that has been known by medical experts for years. Notice that many of the sources below are at least 20-30 years old. Each conclusion is firmly grounded in scientific and medical fact. There is not even a hint of uncertainty…what is stated below is known as clear fact in the medical community. Today, our incredible technology—including 3D and 4D ultrasounds provides “windows into the womb” and allows you and me to see for ourselves what doctors, geneticists, and embryologists have known for so long…that every preborn child is a unique individual; a living person. And shouldn’t our laws protect everyone?

“The cell (zygote) results from fertilization of an oocyte by a sperm and is the beginning of a human being. Each of us started life as a cell called a zygote.” Dr. Keith L. Moore1

“(Fertilization is) that wondrous moment that marks the beginning of life for a new unique individual.” Dr. Louis Fridhandler2

“A new individual is created when the elements of a potent sperm merge with those of a fertile ovum, or egg.” Encyclopedia Britannica3

“I have learned from my earliest medical education that human life begins at the time of conception….I submit that human life is present throughout this entire sequence from conception to adulthood and that any interruption at any point throughout this time constitutes a termination of human life….I am no more prepared to say that these early stages [of development in the womb] represent an incomplete human being than I would be to say that the child prior to the dramatic effects of puberty…is not a human being. This is human life at every stage….” Dr. Alfred M. Bongioanni—professor of pediatrics and obstetrics at the U. of Penn.4

“[A]fter fertilization has taken place a new human being has come into being.” “[This] is no longer a matter of taste or opinion,” and “not a metaphysical contention, it is plain experimental evidence. Each individual has a very neat beginning, at conception.” Dr. Jerome LeJeune—professor of genetics at the U. of Descartes in Paris, discoverer of the chromosome pattern of Down’s syndrome5

“It is incorrect to say that biological data cannot be decisive….It is scientifically correct to say that an individual human life begins at conception….Our laws, one function of which is to help preserve the lives of our people, should be based on accurate scientific data.” Professor Micheline Matthews-Roth, Harvard University Medical School6

“The beginning of a single human life is from a biological point of view a simple and straightforward manner—the beginning is conception. This straightforward biological fact should not be distorted to serve sociological, political, or economic goals.” Dr. Watson A. Bowes, University of Colorado Medical School7

“The basic fact is simple: life begins not at birth, but conception.” Ashley Montague, geneticist and professor at Harvard and Rutgers (unsympathetic to the pro-life cause)8

“Modern technologies have convinced us that beyond question the unborn child is simply another human being, another member of the human community, indistinguishable in every way from any of us.” Dr. Bernard Nathanson, internationally known obstetrician and gynecologist, cofounder of NARAL9 (statement made as an atheist, views based on the biological facts, nothing even remotely religious).

“I oppose abortion. I do so, first, because I accept what is biologically manifest—that human life commences at the time of conception—and second, because I believe it is wrong to take innocent human life under any circumstances. My position is scientific, pragmatic, and humanitarian.” Dr. Landrum Shettles, obstretrician-gynecologist at Columbia-Presbyterian Medical Center in New York10, his intrauterine photos of preborn children appear in over 50 medical textbooks

“The majority of our group could find no point in time between the union of sperm and egg, or at least the blastocyst stage, and the birth of the infant at which point we could say that this was not a human life.” The First Internation Symposium on Abortion11

“Physicians, biologists, and other scientists agree that conception marks the beginning of the life of a human being—a being that is alive and a member of the human species. There is overwhelming agreement on this point in countless medical, biological, and scientific writings.” The Official Senate Report on Senate Bill 158, the “Human Life Bill”12

Holocaust scholar Raul Hilberg believes that the key to the annihilation of the Jewish people was the use of degrading words such as “useless eaters” and “garbage” that made them seem less than human and blinded society to the fact that real people were being killed.13 Today, our preborn children are often called “venereal diseases,” “debris,” “garbage,” “refuse,” “parasites,” and “blobs.” Such terms are all used to dehumanize these little children who cannot speak for themselves. Because science and medicine is so clear in its determination of when life begins, we know from a factual standpoint that every preborn child is a human being. Naturally, every human being is also a person. The Colorado Personhood Amendment recognizes this simple fact of life.

So, in November, please vote YES on Amendment 48. After all, in your heart, you know she’s a person…
