摘要

While arthropod phytogeny remains controversial, comparative studies of the genetic control of segmentation and of the nervous system have begun to throw light on how mandibulate arthropods (myriapods, crustaceans and insects) reached their current level of morphological and behavioural complexity. Insects and crustaceans show remarkable similarities in the construction of their brains, suggesting that their common ancestor had typically arthropod behaviour, while developmental genetic studies are consistent with this ancestor having had distinct head, trunk and tail regions. This conclusion contrasts with the influential view, drawn from comparative embryology and functional anatomy, that insects and crustaceans evolved independently from a simple worm-like organism, perhaps resembling an annelid.
