The remarkably high level of colony organization found in the honey bees and stingless bees (family Apidae) is extremely rare among animals. Yet there is controversy over whether these two groups independently evolved advanced eusocial behavior or inherited it from a common ancestor. Phylogenetic analyses of DNA sequence information from the mitochondrial genome (large-subunit ribosomal RNA gene) of representative apid bees suggest that advanced eusocial behavior evolved twice independently within this assemblage. These results depart from previous hypotheses of apid relationships by indicating a close phylogenetic relationship between the primitively eusocial bumble bees and the stingless bees.
在蜜蜂和无刺蜂(蜜蜂科)中发现的高度发达的群体组织在动物界极为罕见。然而,关于这两个群体是独立进化出高级群居行为还是从共同祖先那里继承而来,存在争议。对代表性蜜蜂线粒体基因组(大亚基核糖体RNA基因)的DNA序列信息进行的系统发育分析表明,高级群居行为在这个类群中独立进化了两次。这些结果与之前关于蜜蜂关系的假说不同,表明原始群居的熊蜂和无刺蜂之间存在密切的系统发育关系。
