No, but nobody's ever claimed they did either. You simply asked for a mechanism by which abortions ocurr naturally, and I provided it for you.
Okay, evolution has supplied us with an amazing brain that allows to think rationally and to some degree override our primitive instincts, which tell us that we should make lots of babies to ensure the survival of the human race. Here are some rational reasons that support "artificial" abortion:
1) To benefit the parents: The parents might not want a baby, or are not financially capable of raising a baby at the time the pregnancy ocurres. The mother might not want to go through a hard pregnancy with a potentially dangerous birth (deaths during childbirth are very rare in the most developed countries, but they do occur).
2) There's something wrong with the fetus: If there's something wrong with the fetus abortion might be the best alternative both for the fetus and the parents. Let's say there's a high risk that a child will be born with a severe mental or physical incapability, like Down's syndrome. Raising such a child is extremely hard for the parents (trust me, I know people who have a kid with Down's), so abortion is definately justifiable in cases like that.
3) For the sake of humanity!: With overpopulation being a real problem in the World, abortion of unplanned pregancies are somewhat justifiable. It's not the best way to handle overpopulation (condoms in Africa and such help much more), but every little bit helps. Parents who already have what they consider to be enough children could also consider abortion of unplanned pregnancies.
There are probably more, but I'm too tired to think clearly atm.
And, stan: Abuse? I merely point out your obvious mistakes when you say something flabbergastingly stupid. Learn how to handle criticism.
