When a new species is found to fit none of the existing genera in a family, taxonomists usually respond by:

Answer: Erecting a new genus after comparing its characters with related taxa.

  • A Placing it into whichever existing genus seems closest in appearance
  • B Erecting a new genus after comparing its characters with related taxa
  • C Assigning it directly to a kingdom without intermediate ranks
  • D Setting the specimen aside as unclassifiable for the time being

Correct answer: B. Erecting a new genus after comparing its characters with related taxa

Explanation: Taxonomy is a dynamic process: when a species does not fit known genera after careful comparison of shared and distinguishing characters, a new genus may be described to accommodate it.

The taxonomic hierarchy narrows from Kingdom (broadest, covering the most organisms but fewest shared traits) down to Species (narrowest, fewest organisms but most shared traits) - every level in between is a progressively more specific subset of the one above it.

Biodiversity, taxonomy, binomial nomenclature, the taxonomic hierarchy, and taxonomic aids like herbaria and botanical gardens. The foundational first chapter of NCERT Biology.
