Verified step by step guidance1
Understand the hierarchy of biological classification, which is organized from broad to specific: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Recognize that as you move down the hierarchy from Domain to Species, the organisms within each group become more closely related.
Identify that 'Genus' is a more specific taxonomic group than 'Class', 'Order', or 'Family', meaning organisms within a Genus are more closely related to each other than those in the broader groups.
Recall that organisms within the same Genus share a more recent common ancestor compared to those in higher taxonomic levels like Family or Order.
Conclude that among the options provided, 'Genus' is the taxonomic group where organisms are most closely related, as it is a more specific classification than Class, Order, or Family.
