Continental connection: North, South America linked much earlier than thought | The Why Files
The American continents were joined 10 million years before the accepted date. What does this say about life in the Americas?. The North–South divide is broadly considered a socio-economic and political divide. Generally The Global South is made up of Africa, Latin America, and developing Asia including the Middle East. The North is home to . Globalization: The Politics of Global Economic Relations and International Business. Durham, N.C. It is very controversial whether or not North and South America are connected by land. The Panama Canal crosses through Panama from the Pacific coast to the.
Economic Development is a measure of progress in a specific economy. It refers to advancements in technology, a transition from an economy based largely on agriculture to one based on industry and an improvement in living standards. The Brandt Line is shown in bold. Digital and technological divide[ edit ] World's ISS space centres The global digital divide is often characterised as corresponding to the north—south divide; however, Internet use, and especially broadband access, is now soaring in Asia compared with other continents.

This phenomenon is partially explained by the ability of many countries in Asia to leapfrog older Internet technology and infrastructure, coupled with booming economies which allow vastly more people to get online.
This facilitated an uneven diffusion of technological practices since only areas with high immigration levels benefited.
Immigration patterns in the twenty-first century continue to feed this uneven distribution of technological innovation. Roosevelt signed new economic agreements with Latin American governments in an effort to restore U.
On the Ancient Relations between New Zealand and South America, by Hermann von Ihering
There was a serious crisis with Mexico over that nation's expropriation of foreign petroleum companies in The United States obtained defense sites, critical in Brazil, and virtually incorporated the Mexican economy into the U. Latin American rural workers, especially in Mexico, Central America, and the Caribbean, migrated to urban factories. Mexicans worked on U.
The formal culmination of the regional approach was the Inter-American Treaty of Reciprocal Assistance and the Organization of American States In the postwar era, the United States shifted its political and economic concerns to Europe and Asia and tried to break down hemispheric economic barriers to U.

Latin American leaders pressed for increased U. Marshall Plan for war-torn Europe. After the Korean War erupted, the United States emphasized regional and bilateral security agreements and became increasingly concerned about Communist influence in Latin America.
In the Central Intelligence Agency brought down a non-Communist leftist government in Guatemala; infollowing several years of civil strife and a protracted guerrilla struggle, Fidel Castro toppled the government of dictator Fulgencio Batista in Cuba. Kennedy 's — first hemispheric crisis.
By the time of Kennedy's death in NovemberU. When President Lyndon Johnson — dispatched twenty thousand troops to the Dominican Republic in the spring ofon the pretext that the rebellion there would create "another Cuba," Latin Americans were persuaded that Washington's commitment to social justice had dissolved.
But the Alliance for Progress fueled Latin America's economic modernization at the expense of democratic government and social justice for the poor, thus perpetuating the dual society of rich and poor. This was most evident in such countries as Mexico and Brazil, which enjoyed impressive economic growth from the s but where social inequities were severe.
By the s, with the U.
Latin American leaders increasingly supported a hemispheric economic agenda diverging from that of the United States and also backed Panama's call for a new canal treaty. He signed a canal treaty with Panama, criticized violations of human rights in Latin America, and initially supported the Sandinista revolution that brought down Anastasio Somoza Debayle in Nicaragua.
By the end of his administration many Americans believed that such reformist approaches to Latin America distracted from the real security risks the United States confronted in the region. Rocks like this polished piece, from Panama's north coast, contain zircon crystals that will later be eroded and transported in water. Between 13 and 15 million years ago, zircon grains traveled along rivers from Panama to northwestern South America. Rollover image to see an electron micrograph of a zircon from Marathon County, Wis.
The super-hardy zircon minerals survive most geological beatings and allow dating of the cooling rock in which they formed. David Farris, Photo 2: However, in geologic strata that were buried from 13 to 18 million years ago, they found some zircons carrying that Panamanian zircon fingerprint.

What did the Panamanian Isthmus look like during the middle Miocene 13 to 15 million years ago? River sediment deposits found in Columbia with Panamanian zircons evince at least segments of the Panama volcanic arc had risen from the seafloor and bound with South America by this time.
El Valle volcano was surfacing, so only shallow, intermittent seaways, if any, would have been allowed between the ocean basins. The Why Files; one on right: The next step in dating the seaway closure looks at transport: How did these zircons get from Panama to the continent? Zircons can travel through the atmosphere once lofted in a volcanic eruption. But that explanation fails for some of the young zircons found in South America, which apparently formed in molten rock that cooled underground.
