Quote:The apparently increasing prevalence of caring behavior for the incapacitated as humans evolved suggested whether that particular band survived is a mere quibble. That trait, survived and prospered.
I'm not convinced that it is a "trait" as much as a cultural phenomena which was itself an outgrowth of the development of language/symbolic thinking. Again, where else does that appear in the natural world? In this humans are quite unique... not because of some stupid god story!
