Relationships of Platyhelminthes excluding Acoelomorpha to each other    The oldest confidently identified parasitic flatworm fossils are cestode eggs found in a Permian shark coprolite , but helminth hooks still attached to Devonian acanthodians and placoderms might also represent parasitic flatworms with simple life cycles. This makes it difficult to work out both their relationships with other groups of animals and the relationships between different groups that are described as members of the Platyhelminthes. Since then molecular phylogenetics , which aims to work out evolutionary “family trees” by comparing different organisms’ biochemicals such as DNA , RNA and proteins , has radically changed scientists’ view of evolutionary relationships between animals. Platyzoa are generally agreed to be at least closely related to the Lophotrochozoa , a super phylum that includes molluscs and annelid worms. The majority view is that Platyzoa are part of Lophotrochozoa, but a significant minority of researchers regard Platyzoa as a sister group of Lophotrochozoa.

This style was further improved by the Australian champion swimmer, Richmond “Dick” Cavill the son of swimming instructor Professor Richard “Frederick” Cavill who developed the stroke with his brother “Tums”.
