Deep metazoan phylogeny.

摘要: We reconstructed a robust phylogenetic tree of the Metazoa, consisting almost 1,500 taxa, by profile neighbor joining (PNJ), an automated computational method that inherits efficiency algorithm. This supports one proposed in latest review on metazoan phylogeny. Our main goal is not to discuss aspects phylogeny itself, but rather point out PNJ can be valuable tool when basal branching pattern large must estimated, whereas traditional methods would computationally impractical.
