蚂蚁的翅膀多面性在1.25亿年前进化过一次，一直是它们惊人进化成功的关键。我们描述了繁殖(有翅)和不育(无翅)蚂蚁等级的翅膀原基下的网络中几个基因的表达。我们发现，在四个蚂蚁物种的有翼物种中，网络中的几个基因的表达是保守的，而在没有翅膀的物种中，网络中的中断点在进化上是不稳定的。蚂蚁翅膀发育网络的同时进化稳定性和保守性可能在该类群的形态多样化中发挥了重要作用，并可能是动植物多物性发育和进化的一般特征。
Wing polyphenism in ants evolved once, 125 million years ago, and has been a key to their amazing evolutionary success. We characterized the expression of several genes within the network underlying the wing primordia of reproductive ( winged) and sterile ( wingless) ant castes. We show that the expression of several genes within the network is conserved in the winged castes of four ant species, whereas points of interruption within the network in the wingless castes are evolutionarily labile. The simultaneous evolutionary lability and conservation of the network underlying wing development in ants may have played an important role in the morphological diversification of this group and may be a general feature of polyphenic development and evolution in plants and animals.
