Adoption

In my last post about reproduction, I tried to explain why we may reproduce, even in a crowded world, in terms of the right of self preservation.  Having a child (and I don't mean 10 children) is a means of survival. Not literally, of course.  We don't lengthen our own lifespans by having children.  But children feel to their parents a bit like second selves, so mortality is easier to face,
