Taxonomy
Taxonomy is the classification of living and extinct organisms. The term is derived from the Greek taxis (“arrangement”) and nomos (“law”) and refers to the methodology and principles of systematic botany and zoology by which the various kinds of plants and animals are arranged in hierarchies of superior and subordinate groups.
Popularly, classifications of living organisms arise according to need and are often superficial; for example, although the term fish is common to the names shellfish, crayfish, and starfish, there are more anatomical differences between a shellfish and a starfish than there are between a bony fish and a human. Also, vernacular names vary widely. Biologists have attempted to view all living organisms with equal thoroughness and thus have devised a formal classification. A formal classification supports a relatively uniform and internationally understood nomenclature, thereby simplifying cross-referencing and retrieval of information.
Carolus Linnaeus, who is usually regarded as the founder of modern taxonomy and whose books are considered the beginning of modern botanical and zoological nomenclature, drew up rules for assigning names to plants and animals and was the first to use binomial nomenclature consistently, beginning in 1758. Classification since Linnaeus has incorporated newly discovered information and more closely approaches a natural system, and the process of clarifying relationships continues to this day. The table below shows the seven ranks that are accepted as obligatory by zoologists and botanists and sample listings for animals and plants.

In 17th-century Holland a speculative frenzy erupted over the sale of tulip bulbs. Tulips had been introduced into Europe from Turkey shortly after 1550. Demand for new varieties soon exceeded the supply, and prices rose to astonishing heights. The craze, known as the tulip mania, reached its peak in Holland in 1633-37. Homes, estates, and industries were mortgaged so that bulbs could be purchased; bulbs of rare varieties sold for the equivalent of hundreds of dollars each. The crash came in 1637, when almost overnight the price structure collapsed, sweeping away fortunes and leaving behind financial ruin for many Dutch families.

Wall Street, which was recognized even before the Civil War as the financial capital of the US, is narrow and short, extending only about seven blocks across part of southern Manhattan in New York City. It was named for an earthen wall built by Dutch settlers in 1653 to repel an expected English invasion.
