Compares newly generated myxozoan assemblies and Polypodium with other cnidarians, linking parasite body-plan reduction to genome reduction.
Claim ledger
New myxozoan genomes and phylogenomic tests place the sampled parasites within Cnidaria and associate extreme body reduction with genome reduction; this does not identify their exact ancestor or origin time.
claim:taxon:myxozoaMyxozoa has no supported scalar temporal range in the cited evidence: phylogenomics resolves a cnidarian placement and genome reduction but provides no fossil or calibrated origin boundary, so the former 0–0 placeholder is withheld.
