Organisms generate shapes across size scales. Whereas patterning and morphogenesis of
macroscopic tissues has been extensively studied, the principles underlying the formation of …

Background This study sheds light on the genetic blueprints of chaetogenesis (bristle
formation), a complex biomineralization process essential not only for the diverse group of …

Polychaetes, echinoids and gastropods have been proposed as tracemakers for Bolonia
Meunier, an elongate positive epirelief trace fossil characterized by two lobes composed of …

Chaetae are among the most extensively studied structures in polychaetes, serving as a
defining morphological trait for annelids. Capitella teleta stands out as one of the few …

Phylotranscriptomic studies of the past decade have repeatedly placed Oweniidae together
with Magelonidae, as the sister group to remaining annelids. This newly established …
