Document Summary
Organisms are product of evolution, dynamic process that does not easily accommodate rigid definitions. Variation in reproductive patterns complicates application of the species concept, so does hybridization. Hybridization: when two species interbreed and produce fertile offspring: reproduction involving more than one species. Taxonomy: the science of the classification of organisms into an ordered system that indicates natural relationships: first used by carolus linnaeus. Developed basic system of naming/classifying organisms that biologists have used for more than 2 centuries. First part of the name identifies genus: a linnaean taxonomic category ranking below a family and above a species. A group of species with similar characteristics arctos is brown bear: convention states the first letter of a generic name is always capitalized. Entire binomial is italicized (underlined in handwritten work: specific epithet is never used without full/abbreviated generic name preceding it. Same species name used for different genera. First use of organism"s binomial name is written in.
