Study Notes
Key Concepts for Biology Classification Exam
- Binomial nomenclature provides species with a scientific name that has two parts.
- The first part of the scientific name is the genus name.
- The second part of the scientific name is the specific name that identifies the particular species within that genus.
- Other terms to be familiar with include Linnaeus, genus, species, Mammalia, derived character, cladograms, common ancestry, kingdom of eukaryotes, and kingdom of fungi.
Questions to consider
- Common names are not useful for scientists when naming new species.
- The Linnaean system of classification involves or uses binomial nomenclature.
- The format that species are named is the binomial system of classification.
- The two highest levels of taxa in the Linnaean system are Domain and Kingdom.
- Traditional classifications considered two things: anatomical/morphological data and fossil records
- During Linnaeus' time, life was divided into two kingdoms: Animalia and Plantae.
- Organisms in the kingdoms Eubacteria and Archaebacteria were previously grouped in a kingdom called Monera.
- The two domains composed of only unicellular organisms are Bacteria and Archaea.
