took this from a pro life website, thought the part concerning brain waves was particularly relevant
When a woman is pregnant, science tells us that the new life she carries is a complete and fully new human being from the moment of fertilization. By the time most abortions can be performed, the baby already has a beating heart and identifiable brain waves. The baby living in her mother is as distinct and unique a new person/human being as you are from me, and as deserving of protection under the law as we are.
The baby every mother carries as she faces a life and death decision has a beating heart at 18 days after fertilization and brain waves as early as six weeks after fertilization. Most abortions are not performed until nine weeks of the pregnancy. Even RU 486 chemical abortions can't be done until after six weeks.
