The Argument (page 5)
- Five weeks after conception, the embryo has developed smaller organs
such as a bony jaw, and by six weeks, the vertabra column, ribs, a
fully functional heart, fingers, and nostrils. The baby also has a
developing nervous system. The brain waves can be recorded at an average
of 40 days after conception. (Death is often defined as the cessation
of brain waves), this guarantees the individual life of the fetus.
- By 7 weeks, the baby's pancreas, bladder, kidneys, tongue, larynx, and
muscles begin to appear.
- By eight weeks, the embryo has ears, fingers, and toes, and all needed
body parts are developed or are developing.
Nine weeks into the pregnancy (about 2 months), the baby can feel pain
- At ten weeks, the baby has developing fingernails, and also begins to
move by itself.
-
By eleven weeks the baby has the fingerprints that will identify it for
the rest of its life.
- At twelve weeks an ultrasound can tell whether the baby is a boy or a
girl. It is able to swallow, and its kidneys are able to make urine.
- Fourteen weeks into pregnancy, the fetus has fully developed legs.
It can kick, sleep, and move its head.
- Twenty weeks after conception, babies respond to small stimulations,
e.g. "to a brush on its lips by sucking."
