The application of binomial nomenclature is now governed by various internationally agreed codes of rules, of which the two most important are the International Code of Zoological Nomenclature (ICZN) for animals and the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants.uch a name is called a binomial name (which may be shortened to just binomial), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus.

The oldest known civilization in South America, as well as in the Western Hemisphere as a whole, the Norte Chico civilization-c. 3200 BC - 1800 BC-comprised several interconnected settlements on the Peruvian coast, including the urban centers at Aspero and Caral.he earliest proto-urban settlements with several thousand inhabitants emerged in the Neolithic. The first cities to house several tens of thousands were Memphis and Uruk, by the 31st century BC (see Historical urban community sizes).
