The acoel worm has recently emerged as a model organism for studying whole-body regeneration and embryonic development. Previous studies suggest that post-transcriptional mechanisms likely play important roles in whole-body regeneration. Here, we establish a resource for studying microRNA-mediated gene regulation, a major aspect of post-transcriptional control in animals.

Vertebrates acquired various novel traits that were pivotal in their morphological evolution. Domain shuffling, rearrangements of functional domains between genes, is a key molecular mechanism in deuterostome evolution. However, comprehensive studies focusing on early vertebrates are lacking.

With its bag-like appearance, spiny ornament and single opening, is one of the most enigmatic animals of the early Cambrian Kuanchuanpu Formation ( 535 Ma) and has been at the heart of debates concerning the origin of two major animal lineages: the deuterostomes and the ecdysozoans. Although Ecdysozoa is now the most plausible option, key aspects of its palaeobiology have remained elusive. I suggest here that was the possible larval stage of one of the numerous scalidophoran worms that co-existed with it in the Kuanchuanpu biota, especially those with bilateral pairs of broad-based sclerites such as .

Crinoids belong to the Echinodermata, marine invertebrates with a highly derived adult pentaradial body plan. As the sister group to all other extant echinoderms, crinoids occupy a key phylogenetic position to explore the evolutionary history of the whole phylum. However, their development remains understudied compared with that of other echinoderms.
