Area of Science:

  • Zoology
  • Evolutionary Biology
  • Phylogenetics

Background:

  • Annelida, a segmented animal group, is crucial for understanding evolution, yet its basal relationships remain unclear.
  • Previous studies lacked a robust phylogeny, hindering insights into annelid evolutionary history and ancestral traits.

Purpose of the Study:

  • To reconstruct a robust phylogeny of Annelida using transcriptomic data.
  • To investigate the basal relationships and ancestral characteristics of annelids.

Main Methods:

  • Transcriptomic data analysis from 305 to 622 proteins (68,750–170,497 amino acid sites).
  • Phylogenetic analyses to resolve annelid relationships, including basal taxa.
  • Ancestral character state reconstruction.

Main Results:

  • The study resolves annelid relationships, placing Chaetopteridae, Amphinomidae, Sipuncula, Oweniidae, and Magelonidae in basal positions.
  • Myzostomida are nested within Annelida as the sister group to Errantia.
  • Basal annelids exhibit diverse lifestyles, including tube-dwelling, deposit feeding, and carnivorous forms.
  • Ancestral annelids likely possessed sensory palps, bicellular eyes, biramous parapodia with chaeta, and lacked nuchal organs.

Conclusions:

  • The reconstructed phylogeny provides a framework for understanding annelid evolution.
  • Early annelid diversification, including Sipuncula fossils at 520 Ma, likely occurred in the Lower Cambrian.
