Life begins at fertilization, science teaches

Science teaches without reservation that life begins at fertilization (conception). It is a scientific fact that an organism exists after fertilization that did not exist before. This new organism has its own DNA distinct from the mother and father, meaning that it is a unique person. As the embryo grows, it develops a heartbeat (22 days after fertilization), its own circulatory system, and its own organs. From fertilization, it is a new organism that is alive and will continue to grow and develop as long as nutrition is provided and its life is not ended through violence or illness.

It is indisputably human, as it has human DNA.

The offspring of two members of a species is always the same type of creature as the parents. No two dogs will ever conceive and give birth to a cat; no fish egg will ever produce a snake. According to all the laws of nature, the preborn baby is human.

Scientific textbooks proclaim this fact. Keith L. Moore’s The Developing Human: Clinically Oriented Embryology (7th edition, Philadelphia, PA: Saunders, 2003) states the following:

A zygote [fertilized egg] is the beginning of a new human being. Human development begins at fertilization, the process during which a male gamete … 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.

The term “zygote” is a scientific term for the new life that is created when the sperm and the egg combine. “Oocyte” is another term for the egg cell, the cell released by woman’s ovary which travels down the fallopian tube and is fertilized by the male sperm.
