| | The Platyhelminthes and the Acoela |
 | | The Platyhelminthes may well prove to be polyphyletic, but conclusive evidence for that is not yet available. | | | The Acoela and its relationship to the Platyhelminthes | | | In any event, it is likely that all three platyhelminth clades (Acoelomorpha, Catenulida, and Rhabditophora) originated through a process of progenesis from a large-bodied, coeolomate ancestor (Rieger, 1986, 1994; Tyler, 2001) even if those are independent origins. |

| | Recent molecular studies suggest that the Platyhelminthes as a whole may even be polyphyletic, having arisen as two independent groups from different ancestral groups. | | | A few trace fossils have been reported that were probably made by platyhelminths (Alessandrello et al., 1988), and fossil trematode eggs have been found in Egyptian mummies and in the dried dung of Pleistocene ground sloth. | | | To find out more about tapeworms and flukes that cause human disease, read this handbook published by the U.S. Food and Drug Administration, view these pages produced by the World Health Organization. |

| | Since most flatworms have only one opening to their digestive tract, they can't feed, digest, and eliminate undigested particles of food simultaneously, as most animals with tubular guts can. | | | Usually the digestive tract has one opening, but in particularly long worms or those with highly branched guts, there may be one or more anuses. | | | The flatworms (Platyhelminthes, Greek "platy"': flat; "helminth": worm) are a phylum of relatively simple soft-bodied invertebrate animals. |
