Evidence Accumulates for Ancient Transoceanic Voyages, Says Geographer

Evidence Accumulates for Ancient Transoceanic Voyages, Says Geographer

Theories on the fringe of science sometimes slowly work their way into the core as the evidence accumulates.

“A classic example is the continental drift [theory],” said cultural geographer Stephen C. Jett, professor emeritus at the University of California–Davis. “In 1955, if you believed in continental drift, you were laughed at. In 1965, if you didn’t believe in continental drift, you were laughed at.”

He was a geography student while this dramatic change in opinion occurred, and he took the example to heart. Encouraged by a professor of his at Johns Hopkins University, Jett started a decades-long investigation into another controversial theory.

Diffusionism

Mainstream anthropology and archaeology holds that Norse expeditions around 1000 A.D. were the only ones to make it to the New World before Christopher Columbus landed in the 15th century. But on the fringes are multiple theories about other successful pre-Columbian expeditions. These theories are placed under the umbrella of “diffusionism.”

“At the outset, I supposed that accumulating the evidence and … putting it out there would change the point of view, at least gradually,” Jett said. “But there hasn’t seemed to have been a lot of that. There’s a good deal of inertia, a good deal of resistance to the whole concept.”

According to Jett, one of the reasons it has been difficult for the concept of early transoceanic voyages to penetrate mainstream history is that it requires a multidisciplinary perspective.

“If you confine yourself to one field, you won’t see it,” he said.

Jett has a multidisciplinary perspective. “Geography is a very broad discipline,” he explained. For example, physical geography gives insight into climate, oceans, landforms, and other elements relevant to long-distance travel. Cultural geography, Jett’s specialty, has helped him see many similarities between ancient Old and New World cultures. But, he said, more biological evidence is emerging to supplement the cultural evidence.

As a graduate student, he discovered precise similarities of blowgun construction in various cultures. The similarities could not, in his opinion, have arisen independently; they clearly point to transoceanic contact and influence. But, he said, more biological evidence is emerging to supplement the cultural evidence. Research into the spread of diseases and plant species, for example, suggests ancient transoceanic contact.

Jett outlined what he calls “six evidentiary revolutions” across several fields that have greatly boosted the diffusionist theories. “We’re getting close to what could be a turning point,” he said. 

It is beyond the scope of this article to explore every “evidentiary revolution” in depth, but we will briefly look at each as discussed by Jett. 

‘Evidentiary Revolution’ No. 1: Maritime Archaeology and Navigation Traditions

A major objection raised against the so-called diffusionist theories is that transoceanic travel would not have been possible with the watercraft and navigation techniques available to ancient peoples who supposedly made it to the New World.

But many replica boats have made the journey in modern times, successfully using only the technology available in antiquity. One famous example is that of Dr. Thor Heyerdahl, who built a boat similar to those used by ancient Egyptians, made of papyrus, and sailed it from Morocco to Barbados in 1970.

Some 20 or more similar, successful voyages have been made, Jett said. He cited as another example the 1985 voyage of Hokule’a, a reconstructed ancient double canoe, from Hawai’i to New Zealand using traditional methods of navigation.

‘Evidentiary Revolution’ No. 2: Parasites and Pathogens

The swapping of parasites and diseases between the Old and New Worlds may have occurred before Columbus. For example, researchers at the National School of Public Health (Escola Nacional de Saúde Pública-Fiocruz) in Rio de Janeiro, Brazil, conducted a review in 2003 of documented parasites found at archaeological sites.

The study,  “Human Intestinal Parasites in the Past,”  states: “Ancylostomids [hookworms] have been found in archaeological sites from both New and Old Worlds. … Human infection has been present in Amerindians far before Columbus. It strongly suggests some kind of transoceanic contact before 7230 ± 80 years ago. … Ancylostomids … require warm and moist conditions to complete their life cycles outside their host, [and] could not have survived during human migration by land through Bering Strait during the last ice age.”

Jett mentioned that tuberculosis and syphilis are among the diseases apparently present in both the Old and New World in antiquity. The theory that they were spread by pre-Columbian human contact remains controversial.

The spread of tuberculosis has been said to have taken place via seals. As for syphilis, it was long thought to have been brought to the Old World by Columbus’ crewmen, who contracted it in the New World. Some evidence in Old World skeletal remains has suggested, however, that it was present in the Old World before Columbus.

Veronica,
dashed well said! I couldn't agree more!

" diffusionists belittle indigenous American populations  "  – that is plain silly – we all want to know the truth – this is or should NOT be about the White man being top dog & nothing was invented by anybody else – if all of our ancestors moved about the planet we obviously all learned from each other, and noone is claiming anything but that. The indigenous American Indians & Australians had developed unique ways of viewing the world, the Europeans have currently developed a technological streak which some say is totally destructive & NOT necessarily what we as humans actually need. That is the current pinnacle(?) of our development, and we may end up discarding all of it and starting again, or may end up being forced to start again if we destroy the planet ! So – American Indians – you have stuff to teach us, sorry about our conceit, will you help us to realize what we may have lost altogether & help us to learn how it all developed – we need you all, and respect your culture. Some of our kind may be a bit ignorant and actually dangerous, but we hope to educate them eventually !

Greed and Gluttony. Take the examples of Nature...Take little bites...Only what you need to cure the hunger and no more. Even the Christians do not take heed of the very same messages in their own written word of righteousness.

How confusing it must have been for the Native Americans when the Christians tried to teach them to read when the teachers could not even comprehend what they were themselves reading...

From research I have done, I am thinking that some of the populations of the world spread from the central point of Atlantis. So many have so much in common and not just ordinary things, but stories, belief and language. Atlantis also had many colonies around the world.

This is especially interesting when one takes into account the similarities between the Aztec lost homeland of Aztlan and Atlantis (take out the last syllable of Atlantis and its practically the same word).

Another interesting point. Read Plato's description of Atlantis, then read Cortez description of Tenochitlan, the Aztec Capital. In my opinion the Aztec were survivors from Atlantis who went west after the destruction instead of East.

Myths & Legends

A vase-scene from about 410 BC. Nimrod/Herakles, wearing his fearsome lion skin headdress, spins Noah/Nereus around and looks him straight in the eye. Noah gets the message and grimaces, grasping his scepter, a symbol of his rule - soon to be displaced in the post-Flood world by Nimrod/Herakles, whose visage reveals a stern smirk.
The Book of Genesis describes human history. Ancient Greek religious art depicts human history. While their viewpoints are opposite, the recounted events and characters match each other in convincing detail. This brief article focuses on how Greek religious art portrayed Noah, and how it portrayed Nimrod in his successful rebellion against Noah’s authority.

Ancient Technology

The School of Athens
Much of modern science was known in ancient times. Robots and computers were a reality long before the 1940´s. The early Bronze Age inhabitants of the Levant used computers in stone, the Greeks in the 2nd century BC invented an analogue computer known as the Antikythera mechanism. An ancient Hindu book gives detailed instructions for the construction of an aircraft –ages before the Wright brothers. Where did such knowledge come from?
