You need a father to have a baby. At what point is he no longer necessary? After sperm meets egg. She- the new baby- is an individual, genetically unique, separate from her Mom. Heartbeat at 21 days, brain waves by 42 days. REM (dream) sleep around 9 weeks (without looking it up.) Can be taught by 8 weeks. Watch The Silent Scream with the sound off, real time ultrasound of an abortion at about 10 weeks gestation.
Had I had the abortion they recommended I have after my rape, one young woman would have died- my daughter. By my hand. No way should that be legal.
