A particular species 'X' has more common characteristics with species'Y', Whereas another species 'Z' has less common characteristics with species 'Y'. Which two species are more closely related ? Why ? On what basis are the eukatyotic organisms further classified ? Why is this basis important? What is the importance of homologous organs ?

Species 'X' is more closely related with species 'Y'. The more closely related species will have more characteristics in common. Hence species X and Y are closely related.
Eukaryotic organisms are further classified on the basis of whether they are unicellular or multicellular.
This basis marks a very fundamental difference in body design, because of the specialization of cell types and tissues.
Homologous organs help to identify an evolutionary relationship between apparently different species.
