Taxonomy A species is a genetically distinct group of organisms, which can interbreed and produce fertile, viable offsprings. External similarity is the common basis for identifying individuals as being members of the same species. Yet a bulldog, a terrier, and a golden retriever are very different in appearance, but they are all dogs because they can interbreed. People can also interbreed with one another, and so can cats, but people cannot interbreed with dogs or cats, nor can these with each other. This shows that individuals of a species are able to interbreed with one another but not with members of other species. Even if they could interbreed…show more content…
The classification levels become more specific towards the bottom of the hierarchy. Many organisms belong to the same kingdom. Fewer belong to the same phylum, and even fewer belong to the same class and so on with species being the most specific classification. The categories from most general to most specific are kingdom, phylum, class, order, family, genus, and species. Each level groups together organisms that share more characteristics with each other. To ensure accurate communication of information, biologists have assigned a two-word scientific name to each organism. This is called Binomial Nomenclature. Nomenclature is a term that refers to a system for naming organisms. In biology the system is "binomial", meaning that two names are used to specifically identify every organism - genus and species. The binomial system uses a two word Latin name. For example, the binomial name for humans is Homo sapiens. Homo, referring to the genus and sapiens referring to the species. Another example is the binomial name for the red maple tree, which is Acer rubrum. Acer is the Latin name for maple, referring to the genus, and rubrum is the Latin name for red referring to the species. The genus name refers to the relatively small group of organisms to which a particular type of organism belongs. The species name is usually a Latin description of some important
