Dated phylogenetic trees are important for studying mechanisms of diversification, and molecular clocks are important tools for studies of organisms lacking good fossil records.

People who live in a country that issues a reserve currency can purchase imports and borrow across borders more cheaply than people in other nations because they don't need to exchange their currency to do so.

By the end of the 20th century, the United States dollar was considered the world's most dominant reserve currency,[1] and the world's need for dollars has allowed the United States government as well as Americans to borrow at lower costs, granting them an advantage in excess of $100 billion per year.[2] However, the U. dollar's status as a reserve currency, by increasing in value, hurts U. exporters.[3] The Dutch guilder emerged as a de facto world currency in the 18th century due to unprecedented domination of trade by the Dutch East India Company.[4] However, the development of the modern concept of a reserve currency took place in the mid nineteenth century, with the introduction of national central banks and treasuries and an increasingly integrated global economy.

British banks were also expanding overseas, London was the world centre for insurance and commodity markets and British capital was the leading source of foreign investment around the world; sterling soon became the standard currency used for international commercial transactions.[5] For example, suppose an American company sells electrical equipment to a buyer in France for one million euros.

The equipment is to be delivered 90 days before the payment is made.

After World War I and the dissolution of the Austro-Hungarian Empire, the Slovaks and Czechs established Czechoslovakia.
