We talked about this in a science class I took a couple years ago. In a broader sense, the biological drive Innocentius mentioned has to do with passing on your genetic code. Greatest love therefore goes to children; however siblings and parents also share much of your DNA, so looking after their welfare also helps increase the chances of your genes being passed on.Originally Posted by Kagemusha
edit: and in an even broader perspective, looking after the good of your community or nation improves the support structures and culture that will protect and nurture those born with your genes, and can also be biologically beneficial.
I think all of that is definitely part of it, but I'm enough of a romantic to think there's more to the picture, and I tried to define it in such a way that it would incorporate biological and/or emotional reasons.
