The existence of behavior fitting the definition of one individual doing 
something for benefit of another is unquestioned.  The problem is how the 
psychological mechanisms behind such behavior came to have evolved.
Now some of them are obvious, such as bears nursing cubs.  Obviously the 
genes of those who did not feed the cubs become less common over time.  The 
harder cases to understand are social insects, "helpers at the nest" in 
birds, and vampire bats.  But all of these are now understood.  (In fact, 
the reciprocal altruism mechanism involved in vampire bats was figured out 
*before* the bat behavior was found.)

It is a good thing you are asking now instead of a few years ago.
Hominids lost serious predation a *long* time ago.  Like every other animal 
lacking predators, the population of our ancestors periodically exceeded 
the food supply.  When it was possible, our ancestors moved over the 
horizon--which is why virtually every possible niche on the globe was 
occupied.
When the entire ecosystem for social primates was filled up and hard times 
were looming, a behavioral switch (activated by the perception of a bleak 
future) turned up the "gain" on the circulation of xenophobic (hating 
others) memes in the tribe, and eventually the hyped up warriors went out 
to do or die against neighbors.  Sort of having to be your own predator.
Repeat this process over a few million years and you get animals who are 
peaceful most of the time, but sync up using memes (any will do) and kill 
each other periodically.
Assuming no logic errors, this is the origin of the power memes have to 
control people.
It certainly accounts for suicide bombers.
This view of humanity is not PC.  Over the years I have taken a lot flack 
(even from a Federal judge) for bringing up topics that humans are most 
uncomfortable with.  But you have to understand the most unpleasant facts 
about our species if you want to do anything about them, or even stay out 
of the way.
