After the Paleoamericans entered the continent, the Beringian Passage was again covered by the sea, so that they were isolated by land from the rest of humanity. Except for uninterrupted communication between Eskimos and Paleo-Eskimos in Alaska and Siberia and the case of a few brief Viking settlements in America in the late 10th or early 11th century, on the coast of Canada and Greenland, there is no conclusive evidence to support a transoceanic contact between pre-Columbian America and the rest of the world, although there is evidence of contact with the Polynesians. After Columbian contact, the question arose as to whether there was contact between the Paleoamericans and the rest of humanity.
After the Columbian contact, various conjectures were put forward to explain the origin of the American Indians, for example, resorting to the myth of Atlantis or the lost tribes of Israel. The advance of scientific research made it possible to demonstrate that there was no material relationship between the origin of the Amerindians and those beliefs, so these old hypotheses were discarded.
Panamerican route by motorcycle
Jonas Deichmann has finished the Pan-American route, or what is the same, from Alaska to Argentina, plus 23,000 kms solo cycling with new world record. On November 24, 2018, Jonas arrived in Ushuaia after 97 days, 21 hours and 10 minutes. The German ultra-cyclist set off on August 19, 2018 from Prodhoe Bay in northern Alaska with his sights set on the world record. The goal: to reach Ushuaia, at the southern tip of South America, in less than 100 days by bicycle and without a support vehicle. The previous world record for the Pan-American route in this mode was 125 days.
The “Pan American Solo” route is already Jonas Deichmann’s third world record. In 2017 he crossed Eurasia, also solo, from Cabo da Roca in Portugal to Vladivostok in Eastern Siberia – 14,331 km in 64 days. Right now Jonas has earned a good rest on the beaches of Brazil and in March he will return to Germany to prepare for his next world record project.
Panamerican Highway North
In the early morning of October 12, 1492, Rodrigo de Triana, an Andalusian sailor aboard the Pinta, sighted dry land for the first time after they had left the port of San Sebastian de La Gomera five weeks earlier. That land was not the Indies that Christopher Columbus’ expedition had sighted, but a newly discovered continent.
Both Christopher Columbus’ and Leif Ericsson’s voyages were a great discovery for their respective times and cultures, but both encountered humans who had arrived much earlier. But… when?
This great drop in sea level caused a multitude of now submerged lands to be above the sea surface, creating natural bridges that allowed the passage of different terrestrial species between areas now separated by large amounts of sea and ocean.
Over the Bering Strait, which today separates Chukotka (in Russia, Asia) and Alaska (in the United States, America), one of these bridges emerged, forming the Beringia region, also known as the Bering Bridge.

An Argentine expatriate physicist talks, among other things, about his career, the state of space physics, Russian-American relations in the post-Cold War era, the emigration of Russian scientists, his conflicts with the creation scientists and the US Arctic policy.
From 1985 to 1991 he was first vice chairman and then chairman of the Arctic Research Commission of the U.S. government. He is currently professor emeritus of the aforementioned Institute of Geophysics and international coordinator of the Solar Terrestrial Energy Program (STEP), which studies the space between the Sun and the Earth. He still holds a number of official committee chairmanships in the United States.
Between 1957 and 1966, there was a formidable evolution at the University of Buenos Aires or, more precisely, at the Faculty of Exact Sciences, which in that period became a research center of international quality. That is why the transition to a North American university took place without any problems. Moreover, the level of the students in Denver was lower than that of the faculty of Exact Sciences in Buenos Aires.
