Phylogenetic relationship among F. candida, O. cincta, L. vannamei, P. monodon, D. pulex, T. castaneum, P. humanus and A. pisum.
The Collembola lineage is represented by F. candida and O. cincta. The Crustacea lineage is represented by two decapods (L. vannamei and P. monodon) and a cladoceran (D. pulex). The Insecta clade is represented by T. castaneum, P. humanusa and A. pisum. The red branches indicate terrestrialization.

Gene Ontology (GO) distribution in F. candida and O. cincta transcriptomes.
The bar chart describes the number of genes assigned to the GO biological processes and molecular functions on level 2 with sequence cut-off of 2 sequences.

Term cloud of over-represented Gene Ontology terms among positively selected genes (PSGs).
(A) GO biological processes over-represented among PSGs in the Hexapoda lineage and (B) in the Collembola lineage. The size of the GO terms is proportional to the p-value obtained in the enrichment test [75], enriched terms were summarized and redundancy was removed with the REVIGO tool [76] using a semantic similarity threshold of 0.7 and D. melanogaster GO Database as reference. The complete dataset of GO enriched terms is presented in the S4 Table.
