摘要

对称性在生命之树中普遍存在1,2,3,4,5 ,生物(包括人类)为繁殖、运动或美观而建造对称结构、10 在没有蓝图或中央组织者的社会性昆虫集体所建造的结构中,对称性是否存在以及如何存在,仍然是一个未决问题。11 在这里,我们展示了蜜蜂在其双面梳子的两侧主动对称地组织巢内容物;79% ± 7% 的细胞内容物与它们背面的对应物相匹配,在巢内形成镜像。通过实验将蜂群限制在梳子的两侧,我们发现独立的蜂群会对称地模仿彼此的巢内组织。然后,我们研究了独立蜂群间接协调巢对称性的机制,结果表明,100%的蜂群(n = 6)都能完美地将它们的育雏巢与随机定位的热源共同定位,这表明热能推动了巢址的启动和早期育雏的产生。巢的对称性还具有适应性益处:与单侧巢相比,双侧巢生长更快,育雏更多,热环境更稳定。最后,在研究进化起源时,我们发现对称性持续存在于蜜蜂的三维(3D)巢穴中,并跨越多个蜜蜂物种,这与双面蜂巢的出现相吻合,双面蜂巢使对称地储存巢内物品成为可能。这项工作表明,与在多细胞生物体内创造对称性的分子机制类似,在动物建筑的集体组织中也存在创造功能对称性的行为过程。

Form, function, and evolutionary origins of architectural symmetry in honey bee nests.

Symmetry is pervasive across the tree of life,1,2,3,4,5 and organisms (including humans) build symmetrical structures for reproduction, locomotion, or aesthetics.6,7,8,9 Symmetry, however, does not necessarily span across levels of biological organization (e.g., symmetrical body plans often have asymmetric organs).10 If and how symmetry exists in structures built by social insect collectives, where there is no blueprint or central organizer, remains an open question.11 Here, we show that honey bees actively organize nest contents symmetrically on either side of their double-sided comb; 79% ± 7% of cell contents match their backside counterpart, creating a mirror image inside the nest. Experimentally restricting colonies to opposite sides of comb, we find that independent colonies will symmetrically mimic each other's nest organization. We then examine the mechanism by which independent colonies can indirectly coordinate nest symmetry, showing that 100% of colonies (n = 6) perfectly co-localize their brood nest with a randomly positioned heat source, indicating that heat drives nest site initiation and early brood production. Nest symmetry also has adaptive benefits: two-sided nests grow more quickly, rear more brood, and have a more stable thermal environment than one-sided nests do. Finally, examining the evolutionary origins, we show that symmetry persists in three-dimensional (3D) nests of Apis mellifera and across multiple Apis species, coinciding with the onset of double-sided combs, which made it possible to symmetrically stockpile nest contents. This work shows that, similar to molecular mechanisms that create symmetry in multicellular organisms, there are behavioral processes that create functional symmetry in the collective organization of animal architecture.
