While this was an extreme example of heroism, such self-sacrificing behavior is common enough in our species to raise a challenge to the TOE.
Hardly. Evolution works on populations. Whether altruism exists in humans or not, I find it very probable to conceive of a scenario in which a population of altruists survive better than an otherwise-equal population of non-altruists.
Perhaps this behavior is evidence for group selection, but most evolutionary biologists seem to believe that group selection plays little, if any role, in evolution.
Huh?
