Insects' 'giant leap' reconstructed by founder of sociobiology
"Eusociality is a CHALLENGE for biologists TO UNDERSTAND because worker castes in eusocial species forgo individual reproduction but rear young that are not their own, a behavior that biologists label altruistic"

"Conventional Darwinian theory could not really explain why one individual should sacrifice its own life, and its precious genes, for the benefit of another individual, unless it could be viewed in terms of group selection, when indi-viduals do it for the benefit of the colony or the species."

It appears that these evolutionary atheist don't have an explanation for it either.
But neither kin nor group selection explains the train rescue example.
It is amazing to me that evolutionists study insects and "lower" animals to figure out why humans do the things that they do. Oh, that's right evolutionists would have us believe that humans are just like chimps and insects, just different genetic material in differing environments.
