Life and Her Children: Glimpses of Animal Life from the Amoeba to the Insects. A. B. Buckley. First published by E. Stanford, London, 1880.
Arabella Buckley finishes with a powerful paragraph on the role of self-sacrifice in evolution. She correctly suggests that future biologists will: “learn that the “Struggle for Existence,” which has taught [insects] the lesson of self-sacrifice to the community, [also teaches that the] devotion of mother to child, and friend to friend … recognizes that mutual help and sympathy are among the most powerful weapons [of survival].”
