Rent objektivt så utgör barnet, även i det allra tidigaste stadiet, ett unikt mänskligt liv i det allra första livsskedet. Detta befästs för övrigt i fullt konventionell medicinsk litteratur, t.ex. här:
“Human life begins at fertilization, the process during which a male gamete or sperm (spermatozoo development) 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. The zygote is the beginning of a new human being (i.e., an embryo).”
–Keith Moore, Clinically Oriented Embryology
“Although life is a continuous process, fertilization is a critical landmark because, under ordinary circumstances, a new genetically distinct human organism is formed when the chromosomes of the male and female pronuclei blend in the oocyte.”
–Ronan O’Rahilly och Fabiola Miller, Human Embryology and Teratology
“The first cell of a new and unique human life begins existence at the moment of conception (fertilization) when one living sperm from the father joins with one living ovum from the mother. It is in this manner that human life passes from one generation to another. Given the appropriate environment and genetic composition, the single cell subsequently gives rise to trillions of specialized and integrated cells that compose the structures and functions of each individual human body. Every human being alive today and, as far as is known scientifically, every human being that ever existed, began his or her unique existence in this manner, i.e., as one cell. If this first cell or any subsequent configuration of cells perishes, the individual dies, ceasing to exist in matter as a living being. There are no known exceptions to this rule in the field of human biology.”
–James Bopp, ed., Human Life and Health Care Ethics
“….it is scientifically correct to say that human life begins at conception.”
–Dr. Micheline Matthews-Roth, Harvard Medical School
“Biologically speaking, human development begins at fertilization.”
–The Biology of Prenatal Develpment, National Geographic
“Each human begins life as a combination of two cells, a female ovum and a much smaller male sperm.
–Clark, J. ed., The Nervous System: Circuits of Communication in the Human Body
“A zygote (a single fertilized egg cell) represents the onset of pregnancy and the genesis of new life.”
–Turner, J.S., och Helms, D.B., Lifespan Developmental
“Almost all higher animals start their lives from a single cell, the fertilized ovum (zygote). The time of fertilization represents the starting point in the life history, or ontogeny, of the individual.”
–Carlson, Bruce M., Patten’s Foundations of Embryology
Lär dig förstå skillanden mellan "början på" och att faktiskt vara något fullt ut, som man därför måste beakta rättigheter till.
En planka kan vara "början på" ett staket, men jag tror knappast du kallar en planka för ett fullvärdigt staket. Utan du definierar staket efter dess funktioner av ex hägna in något, markera en gräns etc...
Ett solrosfrö är "början på en solros, men tror knappast du definierar ett frö som en fullvärdig solros..etc etc
Vetenskapligt och medicinskt så räknar man idag fullvärdigt mänskligt liv vid hjärnans funktioner.
Det är därför vi har hjärndöd som definition.
En befruktning är således "början av" ett mänskligt liv precis som en hjärndöd är "slutet av" ett mänskligt liv. Inget av dessa stadier utgör att vara människa "vid liv".
