The new animal phylogeny: Reliability and implications
Open accessAbstract
DNA sequence analysis dictates new interpretation of phylogenic trees. Taxa that were once thought to represent successive grades of complexity at the base of the metazoan tree are being displaced to much higher positions inside the tree. This leaves no evolutionary "intermediates" and forces us to rethink the genesis of bilaterian complexity.

In the citing paper
“Thus the parental anemones whose genomes we sampled have somewhat less allelic variation than broadcast spawning invertebrates such as sea squirts (~2%) (7) and sea urchins (5-10%) (8), or outbreeding plants like Populus (~2%) (34), but a comparable amount to the pufferfish (0.5%) (35).”

In the citing paper
“The Bilateria thus derive from a common ancestor, a point repeatedly substantiated in current molecular phylogenies (reviewed in Adoutte et al., 2000;Peterson and Eernisse, 2001).”
From Precambrian Animal Life: Probable Developmental and Adult Cnidarian Forms from Southwest China (2002) · cites this paper as Adoutte et al., 2000
In the citing paper
“Cladistic analyses, both morphological and molecular, clearly indicate that the bilaterians are monophyletic, i.e., they derive from a latest common ancestor that gave rise only to bilaterians (see ref. 8).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
