Some forms of infanticide in ancient societies, present-day reprogenetics, preemptive abortions and designer babies have been (sometimes controversially) referred to as eugenic.
While some of this can be explained by society—in countries like China baby boys are favoured and many unborn girls are electively aborted—there are natural processes at work.
While the Pope and Mr.Bush differ on such issues as rock roll the Iraq war and the death penally penalty, they do find coming common ground at in opposing abortion and gay marriage.
