While the RDH is widely recognised as a potential explanation for grouping behaviour in carnivores, especially those for which no other functional behavioural benefits of grouping are evident, it has been extended to the discussion of social behaviour in other species groups as well [ 32- 34].

This problem was recognised by (Balfour, 1883) but he provided no explanation for the apparent difference in position of the embryonic and adult anus.
Although the existence of two invasive phenotypes in CRC is now well- recognised and their prognostic implications proven, the biological explanation for their existence remains unexplained.
These difficulties may serve as an explanation for why many events are not recognised as ADEs.
