The Amphimedon queenslandica draft genome and comparative gene-family analyses document a living demosponge genomic sample; they do not make this species an ancestral animal or a proxy for all Porifera.
claim:taxon:amphimedon_queenslandicaAmphimedon queenslandica
A living Great Barrier Reef demosponge supplied a draft genome for comparisons of animal gene families; this derived sampled species is neither a literal ancestral animal nor a proxy for all sponges.

Claim ledger
Amphimedon queenslandica has no supported scalar species range in the cited evidence: the genome paper samples a living sponge but does not date the species origin or fossil duration, so the former 0–0 placeholder is withheld.
claim:taxon:amphimedon_queenslandica:range-boundary-rc50Srivastava et al. report a draft genome from the living demosponge Amphimedon queenslandica; it contains many metazoan signalling, transcription-factor, adhesion and cell-cycle gene families despite the adult sponge lacking eumetazoan organs. This sampled genome does not represent a literal ancestral animal or all Porifera.
claim:taxon:amphimedon_queenslandica:taxonomyThe study figures adult, embryo and larval stages and reports a draft assembly of approximately 167 Mb; genome content is distinct from a reconstruction of ancestral anatomy.
claim:taxon:amphimedon_queenslandica:morphologyThe primary study identifies Amphimedon queenslandica as a demosponge from the Great Barrier Reef; this profile maps the living sample locality only.
claim:taxon:amphimedon_queenslandica:biogeographyThe study describes the adult as filtering microbes and particulate organic matter with flagellated collar cells; this is living-species ecology, not an early-animal ecological reconstruction.
claim:taxon:amphimedon_queenslandica:ecologyKnown limits
- A missing branch or fossil occurrence does not imply biological absence. Internal nodes are not calibrated divergence estimates.
- PBDB external identifier withheld: no-exact-name-in-snapshot.
