"In this case, the behavior getting selected for would have been something like "protect your group," as in our case, doing that often leads to better survival. It's the core of a group society, anyway. But there's no discernment there, no actual will ensuring that that behavior works to the survival of the individual organism. The line is still "protect the group," which sometimes comes up against our survival instincts and wins out."
Which would also handily explain the behaviour of the dolphins. I'd only argue with it being an error in the first-place. Survival of the individual in evolutionary theory is not the issue - its survival of the species as far as it can and beyond that of life itself.
In other words - the losses of a few overly altruistic members of our species is survivable by the species itself. In fact - it is enhanced by it if one sacrifices itself for many.
Horribly Jesus like that last bit - but I am talking about life and death real situations - not imaginary Gods.
