As you descend the taxonomic ranks from Domain à Species it becomes harder to distinguish and separate closely related organisms from each other and to place them accurately. This is due to mutations in the genes coding for cell surface receptors. By grouping things into their evolutionary relationships in natural classification phylogeny, which studies the relationship, we can see what organisms are closely related to each other with common ancestors and determine using genetics which organisms belong where and help identify organisms which should be classified in certain areas.
