摘要: Novel fossil discoveries have contributed to our understanding of the evolutionary appearance parasitism in flatworms. Furthermore, genetic analyses with greater coverage shifted views on coevolution parasitic flatworms and their hosts. The putative record is consistent extant host associations so can be used put constraints origin parasites themselves. future lies new molecular clock combined additional exceptionally preserved associated hosts coprolites. Besides direct evidence, biogeography potential constrain history, albeit caution needed avoid circularity, a need for calibrations implemented most conservative way. This might result imprecise, but accurate divergence estimates evolution
