An Increase in Animal Diversity was Facilitated by Ecologically-Driven Brain Complexity Throughout the Cambrian. [PDF]
BioessaysThe Brain‐First Hypothesis suggests that the Cambrian transition from animals with simple body plans and simple brains to more complex animals was driven by a selection for brains with increased neural processing, following increased ecological complexity, and the networks underlying brain development were co‐opted to pattern other complex systems ...

Evolution of DNA Methylation Across Ecdysozoa [PDF]
Journal of Molecular Evolution, 2021 Abstract DNA methylation is a crucial, abundant mechanism of gene regulation in vertebrates. It is less prevalent in many other metazoan organisms and completely absent in some key model species, such as Drosophila melanogaster and Caenorhabditis elegans

Evolution of the Cdk4/6-Cdkn2 system in invertebrates. [PDF]
Genes CellsHypothesis on the evolution of the Cdkn2 locus. (a) Loss of Cdkn2 occurred multiple times. (b) Evolution of microsynteny at the Cdkn2 locus. Cdkn2e is a hypothetical transient gene. Abstract The cell cycle is driven by cyclin‐dependent kinases (Cdks). The decision whether the cell cycle proceeds is made during G1 phase, when Cdk4/6 functions.

Support for the Ecdysozoa hypothesis regarding the systematics within Protostomia
, 2023 Sistematika životinja ima dugu tradiciju u biologiji, a metode molekularne filogenetike u zadnjih nekoliko desetljeća dovele su u pitanje brojne tradicionalne stavove u tom području.

20 years of Zootaxa: Tardigrada (Ecdysozoa: Panarthropoda)
Zootaxa, 2021 Over the last two decades, Zootaxa has hosted nearly 200 papers concerning tardigrade taxonomy, systematics, phylogeny, and evolution. A total of 160 researchers from all continents (except the Antarctic) published descriptions of almost 200 new taxa, mostly species, but also genera and higher taxonomic ranks, such as families and superfamilies.
