摘要
一、引言昆虫社会行为的进化涉及两大问题:(1)社会行为的起源和进化过程;(2)社会行为的适应意义。这两个问题都曾使达尔文感到困惑。
Eusocial insects are characterized by four attributes: (1) a great number of adults living together in a group; (2) generations overlapping; (3) cooperation among adults in nestbuilding and brood care; (4) existing reproductive dominance and castes. There is a continuous series from entirely solitary to highly eusocial. This sequence provides clues to the evolutionary steps, by which, eusociality has evolved. Cooperative behaviours could originate from mutualism, kin selection and reciprocation. But, for the reasons of genetics, conflicts always exist in a colony, which must be suppressed to make the eusociality maintained.
