“Pro-lifers” consider the termination of a pregnancy the moral equivalent of taking a newborn life. Their strategies seek to blur distinctions between aborting a fetus and killing a newborn. I argue that an understanding of that relationship—drawing on evidence from centuries of history and millennia of evolution—leads to the conclusion that abortion is the most humane alternative to infanticide, adding to the case for safe, legal, accessible abortion for women who need it.
