A maximum likelihood tree of Argonautes. SH-like approximate likelihood ratios are indicated, values below 0.4 are not shown. Conserved protein domains were predicted with HMMScan. Green branches indicate the expansion of canonical Ago-like (yellow arch) in M. lignano. Blue branches and red branches indicate of PIWI-like (brown arch) in S. mediterranea and M. lignano, respectively. FL-Agos are indicated with the red arch. Species abbreviation are indicated in Table 1
