In a system of classifying ten household items, these can be categorized into groupings based on materials they are made from, uses, size, shape, etc. For example, in just the kitchen alone, a classification system could include large categories like: cookware, appliances, utensils, and then these can be subdivided by size, brand, materials they are made of, etc. With each subdivision of a category, one will eventually get very specific and the object itself will be named. For instance, a non-stick frying pan could be categorized as cookware, then placed into a category by brand name--then further categorized by material its made of--metal, then categorized by size, etc. In taxonomic classification, species are identified and named, according to specific characteristics. In terms of species, the system of binomial nomenclature is used, giving each organism a genus and a species name, based on Anton Von Leeuwenhoek's work. Larger groups are the Kingdom, Phylum, Class, Order, Family, Genus and Species. Members within a species share similar characteristics and are capable of mating with one another.
