Mexico: Archaeological discoveries indicate that the first humans reached the two America by sea 30,000 years ago

Scientists have long believed that humans first entered the Americas about 10,000 years ago, after the formation of the Beringia Bridge that linked Alaska and eastern Siberia during the Pleistocene Ice Age, and enabled humans to cross on foot to the New World.

But a new study from Mexico debunks that hypothesis. A team of anthropologists from Iowa State University believes that humans arrived in the Americas about 30,000 years ago, and the most interesting information is that they did so by sea.

Evidence from Mexico indicates that humans arrived in the New World 30,000 years ago

Anthropologists were studying the origins of agriculture in Mexico’s Tehuacan Valley, where early humans began experimenting with agriculture. They found many plants, that early humans seem to have used, and animal bones believed to have been hunted by humans at the time.

In a cave inhabited by humans in the past called “Coxcatlan Cave”, scientists found these bones in the deepest layer of excavation layers, and the surprise was the age of those bones, which turned out to be much older than expected.

After dating the samples using radiocarbon, the researchers learned that the bones were between 33,448 and 28,279 years old, according to All That’s Interesting.

“We were surprised to find these ancient dates in the deepest layers of the cave, which means we need to take a closer look at the artifacts that we got from those layers,” said Andrew Somerville, an Iowa anthropologist. This is one of the many things that undermine all the sayings and allegations that say that man was originally an ape, as all research indicates that humans were simply humans!

Previous studies only date plant remains and charcoal, which, according to Somerville, indicates a much less accurate age than the age indicated by the bones.

Somerville added that although previous studies had not determined the age of the artifacts found in the lower layer of the cave, it was never expected that they would be this old.

The remains of a human feast

Although anthropologists believe the bones were the remains of a human feast, more evidence is needed to prove this.

Somerville said the type of evidence he and other researchers would look for would include cut marks in the bones as well as evidence that they were boiled or set over a cooking fire.

Somerville added that they would also look for stone tools. Although stone fragments have been found in the deepest layer of the cave in the past, it is still unclear whether they were previously used as tools or if they were just broken pieces of rock.

“If we can find strong evidence that humans made and used these tools, that’s another way we can go forward,” Somerville concluded.

The first Americans to reach the area by sea

If all this evidence indicates that humans settled in that Mexican cave as early as 33,000 years ago, then this means that they could not have reached the continent by land.

This is because the Beringia land bridge was inaccessible until about 15,000 years ago.

Before that, it was covered in Ice Age glaciers, which then melted and flooded the land until the water receded enough for humans to cross on foot.

“Pushing humans to North America more than 30,000 years ago would mean that humans were already in North America before the last glacial peak when the ice age was at its worst,” Somerville explained. The glaciers would have completely closed off any passage overland from Alaska and Canada, which meant that people might have had to come to the Americas by boat across the Pacific coast.”

Previous studies have reached the same conclusions

According to Nature, there have been previous studies postulating that humans reached the New World by sea and that they discovered that world much earlier than commonly expected.

According to the magazine, since 2012, a research team led by a research team from the Autonomous University of Zacatecas in Mexico has been excavating the Chicohote Cave, which is located 2,740 meters above sea level in the Astillero Mountains.

The researchers found nearly 2,000 stone tools, 239 of which were embedded in layers of gravel dating between 25,000 and 32,000 years ago.

Because few of these pieces were found, researchers believe that the cave was used as a refuge only in harsh winters, because the cave is well insulated and provides a haven from snowstorms.

Of course, the ancient ages of these artifacts indicate that the first humans came to the region via the sea and not through the land, according to popular belief.

It is believed that if humans came by boat, they likely sailed from Asia across the Pacific, landed on the western side of America, and then moved east on foot.

Although more evidence is needed to support this theory, the study nonetheless is an intriguing glimpse into the origins of the first Americans and their unprecedented journey to the New World.
