Summary

Female ants are more closely related to their sisters than to their brothers. To maximize the contribution of their genes to the colony, the female workers seem to promote the survival of female over male siblings. A report by Sundström et al. in this week's issue (p. 993) provides data to this effect, and in his Perspective, Seger discusses the historical evolution and implications of these ideas.
