The larval nervous system of the penis wormPriapulus caudatus(Ecdysozoa) [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2016 The origin and extreme diversification of the animal nervous system is a central question in biology. While most of the attention has traditionally been paid to those lineages with highly elaborated nervous systems (e.g. arthropods, vertebrates, annelids), only the study of the vast animal diversity can deliver a comprehensive view of the evolutionary ...

Major host transitions are modulated through transcriptome-wide reprogramming events inSchistocephalus solidus, a threespine stickleback parasite [PDF]
, 2016 Parasites with complex life cycles have developed numerous phenotypic strategies, closely associated with developmental events, to enable the exploitation of different ecological niches and facilitate transmission between hosts.

The Natural History of Teneurins: A Billion Years of Evolution in Three Key Steps
Frontiers in Neuroscience, 2019 The entire evolutionary history of the animal gene family, Teneurin, can be summed up in three key steps, plus three salient footnotes. In a shared ancestor of all bilaterians, the first step began with gene fusions that created a protein with an amino ...

Coevolution of the CDCA7-HELLS ICF-related nucleosome remodeling complex and DNA methyltransferases
eLife, 2023 5-Methylcytosine (5mC) and DNA methyltransferases (DNMTs) are broadly conserved in eukaryotes but are also frequently lost during evolution. The mammalian SNF2 family ATPase HELLS and its plant ortholog DDM1 are critical for maintaining 5mC. Mutations in
