寄生行为的进化可能会催化开发新的生态位，但也会将寄生虫的命运与宿主的命运捆绑在一起。因此，尚不清楚从自由生活的有机体向寄生虫的进化转变是否会导致多样化速度的增加或降低。我们探索了长舌蜜蜂幼虫寄生的进化，发现在10个幼虫分支中，有8个幼虫的多样化比率降低。我们提出了一条幼虫寄生策略进化的途径，发现封闭寄主细胞被寄生，寄主后代被成虫杀死的策略代表着幼虫寄生世系出现的必要的第一步；这最终演变为开放寄主细胞被寄生，寄主后代被专门的幼虫杀死的策略。向寄生开放巢细胞的转变扩大了寄生蜜蜂的潜在寄主范围，并在寄生分支的多样化模式中发挥了基础作用。我们解决了某些蜜蜂家族中幼虫寄生血统的普遍问题，并研究了其他生物体群体中幼虫寄生的进化。
The evolution of parasitic behavior may catalyze the exploitation of new ecological niches yet also binds the fate of a parasite to that of its host. It is thus not clear whether evolutionary transitions from free‐living organism to parasite lead to increased or decreased rates of diversification. We explore the evolution of brood parasitism in long‐tongued bees and find decreased rates of diversification in eight of 10 brood parasitic clades. We propose a pathway for the evolution of brood parasitic strategy and find that a strategy in which a closed host nest cell is parasitized and the host offspring is killed by the adult parasite represents an obligate first step in the appearance of a brood parasitic lineage; this ultimately evolves into a strategy in which an open host cell is parasitized and the host offspring is killed by a specialized larval instar. The transition to parasitizing open nest cells expanded the range of potential hosts for brood parasitic bees and played a fundamental role in the patterns of diversification seen in brood parasitic clades. We address the prevalence of brood parasitic lineages in certain families of bees and examine the evolution of brood parasitism in other groups of organisms.
