Describe the modern system of classification

The modern system classifies organisms into eight levels: domain, kingdom, phylum, class, order, family, genus, and species. The scientific name given to an organism is based on binomial nomenclature. The more classification levels two organisms share, the more characteristics they have in common and the more closely related they are.
