Answer:
Both molecular and morphological comparisons among dugongs and proboscideans species should be conducted
Explanation:
From a molecular biology point of view, it is possible to compare the sequences of dugongs and proboscideans and thus observe the homology level between genes of interest, it in order to establish evolutionary relationships among species. Moroever, by mass spectrometry (MS), it is possible to compare proteins in fossils >1 million years, these comparisons may shed light on the evolutionary origin of one group
