18-1 Finding Order in Diversity

To study the diversity of life, biologists use a system of classification to logically name and group organisms based on similarities and differences. Carl Linnaeus was the first to develop the science of taxonomy.

Because languages vary and some words do not exist in other languages, it was decided very early that Latin would be the universal language of taxonomy. To further simplify the process, Linnaeus devised binomial nomenclature to assign each species a two- word scientific name. Examples: Ursus arctos- Grizzly Bear Homo sapiens – Human Canis familiaris- Dog (pet)

How to write a scientific name: The first name represents the genus to which the animal belongs. This is always capitalized. Ursus arctos The second name represents the species that identifies the species specifically out of it’s relatives.

Linnaeus used seven categories to organize plants and animals. Kingdom- broadest category; Animalia Phylum- shared characteristics; Chordata Class- Broad category of orders; Mammalia Order- Large category of similar families; Carnivora Family- many shared characteristics; Ursidae Genus- hybrids may occur; Ursus Species- regular members of a population; arctos
