Xenacoelomorpha is the sister group to Nephrozoa
The position of Xenacoelomorpha in the tree of life remains a major unresolved question in

Acoelomorph flatworms are deuterostomes related to Xenoturbella
Xenoturbellida and Acoelomorpha are marine worms with contentious ancestry. Both were
originally associated with the flatworms (Platyhelminthes), but molecular data have revised …

The Acoela: on their kind and kinships, especially with nemertodermatids and xenoturbellids (Bilateria incertae sedis)
JG Achatz, M Chiodin, W Salvenmoser, S Tyler… - Organisms Diversity & …, 2013 - Springer
Acoels are among the simplest worms and therefore have often been pivotal in discussions
of the origin of the Bilateria. Initially thought primitive because of their “planula-like” …

A comprehensive analysis of bilaterian mitochondrial genomes and phylogeny
About 2800 mitochondrial genomes of Metazoa are present in NCBI RefSeq today, two
thirds belonging to vertebrates. Metazoan phylogeny was recently challenged by large scale …
