24. Taxonomists give a unique scientific name to each species they know about whether it’s alive today or extinct. The scientific name comes from one of two “dead” languages – Latin or ancient Greek.

25. Rules for Naming Organisms The International Code for Binomial Nomenclature contains the rules for naming organisms All names must be approved by International Naming Congresses (International Zoological Congress) This prevents duplicated names

26. The genus name is written first (always Capitalized). The species name is written second (never capitalized). Both words are italicized if typed or underlined if hand written. Example: Felis concolor or F. concolor Which is the genus? The species? Binomial Nomenclature a two name system for writing scientific names. Turdus migratorius
