Why must the scientific name of an organism be written in italics (or underlined when handwritten)?

Answer: To mark it as a universal, standardised name distinct from common names.

  • A Because italics make a name easier to pronounce in other languages
  • B Italics show that an organism has not yet been formally classified
  • C To mark it as a universal, standardised name distinct from common names
  • D It is just a stylistic habit with no formal rule behind it

Correct answer: C. To mark it as a universal, standardised name distinct from common names

Explanation: Following the binomial nomenclature convention, scientific names are written in Latin and italicised (or underlined) to set them apart as formal, universally recognised names distinct from local common names.

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.
