Which organisms would most look alike?
A: Organisms in the same order
B: Organisms in the same class
C: Organisms in the same phylum
D: Organisms in the same family
Kingdom, phylum, class, order, family, genus and species are the taxonomic ranks.
As we move from kingdom to species the number of organisms belonging to the taxon decreases whereas the similarity between the organism belonging to that taxon increases.
Therefore, from the given option, it is family that will have the organism sharing the most similarities and thus, would look alike.
