Phylogenetic tree of all MED factors, showing high prevalence of duplications across the Elegans supergroup. In most cases, paralogous duplicates likely arose post-speciation, although there are examples that suggest that some species each inherited two or three genes from a common ancestor that later underwent further duplications. The tree was generated by RAxML using the MED DNA-binding domains (Kozlov et al. 2019; Stamatakis 2014).
