Abstract
A recent report by Chen et al. (2014) describes the new Ediacaran Doushantuo acritarchs with fascinating features. Nested within Megaclonophycus-like fossils that exhibit palintomic cell division are multicellular spheroid structures termed matryoshkas, which are interpreted to be germ cells. Such distinctive features of cellular differentiation and germ-soma separation suggest affinities of these with early stem group metazoans. In this commentary, I suggest some alternative interpretations to those elaborated by Chen et al. (2014).
