Placozoa and the evolution of Metazoa and intrasomatic cell differentiation
International Journal of Biochemistry and Cell Biology, 2009The multicellular Metazoa evolved from single-celled organisms (Protozoa) and usually - but not necessarily - consist of more cells than Protozoa. In all cases, and thus by definition, Metazoa possess more than one somatic cell type, i.e. they show-in sharp contrast to protists-intrasomatic differentiation.

The evolution of the placozoa: A new morphological model
Senckenbergiana Lethaea, 2002The evolutionary history of the placozoanTrichoplax adhaerens is reconstructed from a hypothetical ‘gallertoid’ ancestor. According to this approach the Placozoa derived from an early benthic gallertoid stage, the ‘placuloid’. The sequence of morphological transformations leading to the placozoan bauplan can be deduced from biomechanical and functional

, 2023 PREFAZIONE Perché un nuovo testo di Zoologia? La risposta sta innanzitutto nella quantità di nuove informazioni, derivanti dagli studi basati sull’uso di approcci cladistici e molecolari, che hanno rivoluzionato le nostre conoscenze sui rapporti filogenetici tra gli animali, soprattutto invertebrati.

The enigmatic Placozoa part 2: Exploring evolutionary controversies and promising questions on earth and in space [PDF]
BioEssays, 2021 The placozoan Trichoplax adhaerens has been bridging gaps between research discilplines like no other animal. As outlined in part 1, placozoans have been subject of hot evolutionary debates and placozoans have challenged some fundamental evolutionary ...

The enigmatic Placozoa part 1: Exploring evolutionary controversies and poor ecological knowledge
BioEssays, 2021 The placozoan Trichoplax adhaerens is a tiny hairy plate and more simply organized than any other living metazoan. After its original description by F.E.
