Human Development


Week By Week


The life of each individual member of a species begins at conception. Here we encounter an entirely whole and unique human for the very first time! Unlike a car on an assembly line that is built piece by piece, human development is autonomous and self-directed like that of a seed.

Week 1

The early human being increases to over 100 cells within the first week after conception.

Implantation commonly occurs 6 days after after conception when the unborn entity “nests” into her mother’s uterus

Weeks 2-7

By the end of the 20th day, the foundation of the child’s brain, spinal cord and entire nervous system will have been established.

Heart beats about 113 times per minute.

From a scientific point of view, it is indisputable that this tiny little thing is in fact, a very small human. 

Weeks 8-12

At this point every organ found in a fully-grown human is in place in the fetus just waiting to develop. 

Weeks 13-19

Facial features and unique fingerprints are all there.

Eyebrows and hair on the top of the head are beginning to grow, bones are getting harder, and the baby may even be sucking his thumb.

Weeks 20-23

By 20 weeks post-fertilization, the unborn child reacts to stimuli. Surgeons entering the womb to perform corrective procedures on unborn children have seen those babies flinch, jerk and recoil from sharp objects and incisions. In addition, ultrasound technology shows that unborn babies at 20 weeks and earlier react physically to outside stimuli such as sound, light and touch.

The United States is one of only seven countries in the world that permit elective abortion past 20 weeks.

Weeks 24-Birth

24 weeks is the accepted standard of viability, or the time an unborn child has a decent chance of survival outside of the womb.

Abortion is legal through all nine months of pregnancy. The Supreme Court in Roe v. Wade ruled that women have a right to abortion any time an abortion doctor deems the abortion necessary for her “health.” The Supreme Court defined “health” as “all factors—physical, emotional, psychological, familial, and the woman’s age—relevant to the well-being of the patient.” This “health” exception gives abortion doctors the power to nullify any abortion restriction on the grounds that there are “emotional” reasons for the abortion.
