Researchers from the UPV/EHU-University of the Basque Country and CEFAS have discovered a parasite present in seawater and which belongs to a primitive lineage; they have named it Txikispora philomaios. This organism will help to explain how multicellularity developed in animals. Phylogenetic and phylogenomic studies using DNA from this parasite are helping to understand the evolutionary changes and adaptations that enabled the difficult transition to take place from microscopic unicellular organisms to multicellular animals and fungi.
