Beyond kin-bonded benefits, there are also synergistic relationships which 
can benefit both parties, regardless of genetic similarity. Symbiosis 
between different organisms is, in fact such an arrangement. Social groups 
can form for mutual benefit; cooperatives are a good example in the human 
sphere.

Yes, all of them.  More specifically, it is easy to see more altruism being 
displayed in the early Roman republic, as opposed to the later Roman empire, 
where selfish individuals had managed to subvert Rome to serve their own 
selfish purposes.

I would have a hard time rephrasing any better than I did the first time.
