title: [Origin of arthropods and of the clades of ecdysozoa].
abstract: The problem of the origin of the phylum Arthropoda was long considered solved based on evolutionary morphology data. But molecular biological studies of recent years have put forward a new solution that contradicts the old one. Hence, the need arises to review the argumentation of both sides and search for ways to reach a consensus. These two subjects constitute the scope of this paper.
