Verified step by step guidance1
Begin by understanding the hierarchy of biological classification, which is a system used to organize and categorize all life forms. The main ranks in this hierarchy, from most general to most specific, are: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Recognize that each rank represents a level of specificity. As you move down the hierarchy from Domain to Species, the groups become more specific, meaning they include fewer organisms that share more characteristics.
Identify the ranks given in the problem: Family, Genus, Order, and Species. Compare these ranks to the hierarchy to determine their order of specificity.
Understand that 'Order' is a higher rank than 'Family', 'Genus', and 'Species', making it less specific. 'Family' is more specific than 'Order' but less specific than 'Genus' and 'Species'.
Conclude that 'Species' is the most specific rank among the options provided, as it represents the most precise classification, typically referring to a single type of organism with distinct characteristics.
