Note 35 — Chapter III · ToC
Reading edition
A similar condition will be found in the even more complex societary forms of ant-hills. Among the vast population of the ants all the workers and soldiers are arrested in their sexual development, remaining, as it were, permanent children of both sexes. It seems probable that this explains the limit that has been reached in the evolution of these wonderful creatures, which in certain directions have attained to an extraordinary development, and have then become curiously and immovably arrested. See Problems of Sex, by J.A. Thomson and Prof. Patrick Geddes, p. 24; Mind in Animals, by Büchner, p. 60; and Woman and Labour, by Olive Schreiner, p. 78.
