With volume EM, we followed the neuronal targets of the very first pioneer neurons at the apical and posterior ends of the larva of the annelid Malacoceros fuliginosus. We observed that all of these ...

The tool, called PsiPartition, improves both the computational efficiency of the data analysis and the accuracy of the phylogenetic trees that visualize these relationships. The novel method was ...

The phylogenetic distribution of symbioses between eukaryotic hosts and prokaryotes is much wider than previously thought, which reinforces the view that this phenomenon has a role in promoting ...

This research suggests a conservative pattern of ovary organization among clitellate annelids, which may help clarify phylogenetic relationships within the group[1]. Another investigation focused ...

During the peer-review process the editor and reviewers write an eLife assessment that summarises the significance of the findings reported in the article (on a scale ranging from landmark to useful) ...
