Ecdysozoa versus Articulata: clades, artifacts, prejudices
Journal of Zoological Systematics and Evolutionary Research, 2001 The claim that monophyly of the Ecdysozoa is caused by chance similarities in 18S rDNA sequences (Wagele et al., J. Zool. Syst. Evol. Res. 37, 211–223, 1999) is re-analysed from the cladistic point of view. It is shown that the molecular characters supporting the Ecdysozoa do not behave as ‘noisy’ in empirical studies that use the sensitivity analysis ...

Russian Journal of Developmental Biology, 2015
Science has accumulated to date such amounts of valuable and diverse information that no scientists can be encyclopedists (like those of the 17th and 18th centuries). Now every scientist is usually well informed only in one particular area and often needs consultations of other specialists. The current situation in biology is similar.

Origin of arthropods and of the clades of Ecdysozoa
Russian Journal of Developmental Biology, 2013The 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.

Gelsolin in Onychophora and Tardigrada with notes on its variability in the Ecdysozoa
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2017Rearrangements of the filamentous actin network involve a broad range of actin binding proteins. Among these, the gelsolin proteins sever actin filaments, cap their fast growing end and nucleate actin assembly in a calcium-dependent manner. Here, we focus on the gelsolin of the onychophoran Peripatoides novaezealandiae and the eutardigrade Hypsibius ...

Proposing a solution to the Articulata-Ecdysozoa controversy
Zoologica Scripta, 2003Recent studies of animal radiation agree on monophyly of the Bilateria, but there is no consensus about the early radiation of the group. Protostomia and Deuterostomia are usually recognized, with two competing theories regarding the division of the Protostomia: one divides them into Spiralia and Cycloneuralia, the other into Lophotrochozoa and ...

The last common ancestor of Ecdysozoa had an adult terminal mouth
Arthropod Structure and Development, 2019The Ecdysozoa is a major animal clade whose main uniting feature is a distinctive growth strategy that requires the periodical moulting of the external cuticle. The staggering diversity within Ecdysozoa has prompted substantial efforts to reconstruct their origin and early evolution.

The origins and evolution of the Ecdysozoa
2009AbstractEcdysozoa is a clade composed of eight phyla, three of which — arthropods, tardigrades, and onychophorans — share segmentation and have appendages, and the remaining five — nematodes, nematomorphs, priapulids, kinorhynchs, and loriciferans — are worms with an anterior proboscis or introvert.
