Who is Carl Linneaus and what did he do? |

What is nomenclature? |

|
|
What is the order of taxonomic categories? |

|
What is the standard for naming new species? |
Describing new species is a task for a specialist; much research may be needed to be sure a species has not already been described, and to decide if it is sufficiently different from existing species to describe. |

|
What is binomial nomenclature? |
the system of nomenclature in which two terms are used to denote a species of living organism, the first one indicating the genus and the second the specific epithet. |
