From: Tracing the evolution of tissue identity with microRNAs
Phylogenetic relationships between major taxonomic phyla according to [9] and reconstruction of ancestral tissue types based on conserved miRNA expression patterns. NLCA, BLCA and ELCA: the Nephrozoan, Bilaterian and Eumetazoan last common ancestor, respectively. The summary for the BLCA is preliminary owing to the absence of a sequenced acoel genome and miRNA expression data. Representatives of the taxa used in the study of Christodoulou et al. [8] are in bold.
