To Be or Not to Be a Flatworm: The Acoel Controversy

Figure 1

Phylogenetic analysis of 23 animal species using partial sequences of 43 genes.

The acoel Isodiametra pulchra appears as a sister group of the rest of the bilaterians, and not as a member of the Platyhelminthes. Numbers above nodes refer to the maximum likelihood boostraps. Values below nodes represent bootstrap support under CAT. Circled numbers indicate the percentage of individual-loci trees that supported the respective node in the maximum-likelihood analyses of each data-set separately.
