Talk:Altruism

In the NewScientist article "Survival of the Nicest" (full archived version can be read here), the author writes that Darwin "summarised the topic of social insect altruism as 'one special difficulty, which at first appeared to me to be insuperable, and actually fatal to the whole theory'.

However, a reading of the original passage (Chapter 7 of The Origin of Species), Darwin writes:
 * "I will not here enter on these several [other] cases, but will confine myself to one special difficulty, which at first appeared to me insuperable, and actually fatal to my whole theory. I allude to the neuters or sterile females in insect-communities."

Can anyone offer insight for the seeming contradictions between the NewScientist article and the actual context of Darwin's work?
