Difficulty: MediumTaxonomy and Classification

A wildlife biologist identifies an unknown specimen and determines that it belongs to the mammalian order Carnivora. According to the standard Linnaean classification hierarchy, which taxonomic rank immediately follows Order as the classification narrows toward Genus?

  1. A
    Phylum
  2. B
    Class
  3. FamilyAnswer
  4. D
    Species

Answer

Family
In the standard biological classification system, the hierarchy progresses from broadest to most specific: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. Therefore, Family is the rank that immediately succeeds Order and directly precedes Genus.

Step-by-Step Solution

1
Recall the hierarchical sequence of Linnaean taxonomic categories from broadest to most specific.
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
Establishing the standard sequence identifies the precise relative position of each taxonomic rank.
2
Locate the target segment of the hierarchy starting from Order and proceeding toward Genus.
Order is directly followed by Family, which is then followed by Genus.
Identifying the intermediate rank provides the direct answer to the biological classification step.
