If the entire population of the world were put into the land area of Texas, each person would have an area equal to the floor space of a typical U.S. home and the population density of Texas would be about the same as Paris, France. (More on The Over Population Myth).

Fertilization is the exact moment when a new human being comes into existence. This one-celled life which has inherited 23 chromosomes from each parent contains the entire genetic code for every detail of individual human development. It has its own genetically distinct DNA and may have a completely different blood type (not to mention sex) than the mother.

At about eight days after conception, the fertilized ovum (blastocyst) implants in the lining of the uterus. It emits chemical substances which weaken the woman's immune system within the uterus so that this tiny "foreign" body is not rejected by the woman's body.

A baby's heart begins to beat 21 days after conception.

Brain waves start registering on an electroencephalogram (EEG) 42 days after conception. This is the legal standard for determining if someone is alive after birth.

By the eighth week of pregnancy, every organ is present and in place. Everything found in an adult human being can now be found in this tiny embryo which is now only about an inch and a half long.
