a. true
b. false

This statement is false. The binomial nomenclature system was used to classify animals, but not until the 1700s when it was first formally introduced by Carl Linnaeus. In ancient times, plants and animals were instead usually just classified in terms of whether or not they were useful, or divided animals into categories such as 'domestic animals, wild animals, creeping animals, flying animals, sea animals'.
