The hypothetical ancestral animal the Urmetazoa: Telomerase activity in sponges [Porifera]
Sponges (Porifera) represent the lowest metazoan phylum, characterized by ErgoRapido Handheld Vacuum Unit a pronounced plasticity in the determination of cell lineages, and they are the closest related taxon to the hypothetical ancestral animal, the Urmetazoa, from which the metazoan lineages diverged.In a first approach to elucidate the molecular
