1. Which one does this "developed" mean?
a.Some people believe that giving to charity is some kind of instinct,(so it) developed because it benefits our species...(cause-and-effect) : I don't think this makes sense as it usually should be "developing" as a participial phrase.
b.Some people believe that giving to charity is some kind of instinct, (which was) developed because it benefits our species...(to describe some kind of instinct as a non-defining phrase)
2.Does this "should" mean presumption or obligation? As the main clause has "presume", it seems presumption, but I'm not sure.
ex)Some people believe that giving to charity is some kind of instinct, developed because it benefits our species in some way. At first, this seems like a strange idea: Darwin’s theories of evolution presume that individuals should act to preserve their own interests, not those of the species as a whole.But the British evolutionary biologist Richard Dawkins believes that natural selection has given us the ability to feel pity for someone who is suffering. When humans lived in small clan-based groups, a person in need would be a relative or someone who could pay you back a good turn later, so taking pity on others could benefit you in the long run. Modern societies are much less close-knit and when we see a heartfelt appeal for charity, chances are we may never even meet the person who is suffering ― but the emotion of pity is still in our genes.
