During the last ice age, when hunters and gatherers crossed the ancient Bering Land Bridge that connected Asia with North America, they carried something special with them in their genetic code: pieces of ancestral Australian DNA, a new study finds.
Over the generations, these people and their descendants trekked southward, making their way to South America. Even now, more than 15,000 years after these people crossed the Bering Land Bridge, their descendants — who still carry ancestral Australian genetic signatures — can be found in parts of the South American Pacific coast and in the Amazon, the researchers found...
The new research builds on earlier work, first published in 2015, which showed that ancient and modern Indigenous people in the Amazon shared specific genetic signatures — known as the Ypikuéra, or Y signal — with modern-day Indigenous groups in South Asia, Australia and Melanesia, a group of islands in Oceania.1st Americans had Indigenous Australian genes | Laura Geggel | April 02, 2021
Wow. All that “climate change” and sea level change. How was that even possible?>
The sea route is the most logical explanation of how people were able to get to Monte Verde in Chile so early.
Humans began sailing the seas over a hundred thousand years so I believe most native Americans came to the New World by boat. If you have to move yourself, your family, and everything you own then a boat makes a much better option than tracking by foot through frozen, shitty tundra.
2,500 years does not a brief window make....
My understanding is that no artifacts of boats or canoes or rafts of any kind exist from the Bering land bridge period.
It is also hard to understand how you could repair or build a new water craft if your original one was damaged or wrecked.
I am thinking that wood would be in very short supply on the land bridge during the glacial maximum.
Limited wood also means limited cooking and limited warmth.
Almost impossible to understand how enough people survived the coastal journey to the south to create the millions of indigenous settlers that eventually populated North and South America.
There’s no such thing as a “native” American. They all came here from somewhere else. The earliest known, so far, came from around Polynesia to South America by boat. This “Native American” gimmic is used by politicians with a guilt complex.
Must have been a real freeze-over for those Polynesians to get to Hawaii.
Brief? The earliest was 2500 years long, and the second was 1600 years long.
I find it so interesting they seldom mention migration from the east, constantly pushing Asia. The earliest tools found in Eastern US closely match those found in France.
Yeah, because we all know they were both hydrophobic and to stupid to know how to float. Why does this antiquated perspective continue to be repeated?
Two sons were born to Eber: One was named Peleg, because in his time the earth was divided...Peleg means division.
A reasonable inference thus relates Peleg's birth to the Bering Sea land-bridge's parting, whether or not it was actually used for migration.
During both my Undergraduate and Graduate schooling, I was taught the ice free corridor and the human caused mega fauna extintion. The evidence was scarce and probably largely invented or misinterpreted.
The dinosaurs like me are dying off in large numbers every year. Very soon, this nonsense will be purged like the Plitdown hoax. Soon, Science will recognize the coastal route, perhaps along both the Atlantic and Pacific shores as the main routes. If the ice free corridor was ever used, it was infrequent and unimportant.
