An individual human life begins at the "moment of conception".
From this instant on, an individual human being exists.
That life can be ended in a number of ways.
New methods (called abortificients) kill by denying the fertilized egg a place to roost.
Remember, the fertilized egg is a unique individual human being.
Other drugs will eject the individual by destroying his or her means of support. Much like throwing a passenger out of an airplane at 20,000 feet.
RU-486 is the name of the drug used to induce delivery at any time thus ejecting the unborn child.
