LAS CRUCES — The oldest known human footprints in North America have been discovered at White Sands National Park in New Mexico.
Researchers identified approximately 60 fossilized footprints buried in layers of gypsum soil on a large playa in the Tularosa Basin in findings published in the journal Science on Thursday.
By carbon dating seeds embedded in the footprints, the U.S. Geological Survey estimated the prints were up to 23,000 years old.
The article reports researchers believe humans could have crossed from Asia into the Americas 26,000 to 19,000 years ago, through land connecting what is now Russia and Alaska, during the last ice age. From there, they are thought to have settled a now mostly submerged region called Beringia, but found their way south blocked by glaciers.
The discovery could upset existing theories of how human beings came to populate the American continent, and how long ago.
Research over recent decades suggested people reached today's continental North America by boat at least 16,000 years ago. Before that, archaeologists thought the first human arrivals walked through a corridor between glaciers by around 13,500 years ago.
If the dating of the new discovery in New Mexico is correct, it establishes the strongest evidence yet that human beings reached the Americas thousands of years earlier than previously supposed by archaeologists, the paper states, before advancing glaciers closed migration routes from Asia.
"This study illustrates the process of science — new evidence can shift long-held paradigms," U.S. Geological Survey Acting Rocky Mountain Regional Director Allison Shipp said.
Research teams included scientists from White Sands National Park, the National Park Service, the U.S. Geological Survey, Bournemouth University, University of Arizona and Cornell University in consultation with the park’s Native American partners.
Two historic Apache trails cross what is now the park. The descendants of the original Apache who settled in the area are the Mescalero Apache.
“These incredible discoveries illustrate that White Sands National Park is not only a world-class destination for recreation, but is also a wonderful scientific laboratory that has yielded groundbreaking, fundamental research,” White Sands Superintendent Marie Sauter said in a news release.

Dynamic landscape makes dating difficultDavid Rachal, a geomorphologist based in Las Cruces who was not involved in this project, published a research paper in April warning that the geology of White Sands and the bed of Paleolake Otero are dynamic.
Layers of sediment bearing trackways of humans and large ice age animals, or megafauna, have eroded, moved around and exposed layers over time. The lake itself has risen and fallen and the shoreline has shifted.
On Thursday, Rachal said the dynamics make accurate dating of specific tracks very difficult, as when footprints occurring many thousands of years apart might be superimposed.
Rachal praised the team's work before adding one note of caution about how these findings characterize other trackways at the site.
“You can’t dispute the dates, the prints are amazing, everything lines up, it’s perfect,” he said, noting that the team was working in an area with superior conditions for trackway preservation.
“The only thing I’m concerned about is that it’s not that clean of a landscape,” he added, warning that the landscape at White Sands “has experienced a tremendous amount of geologic change over a short timeframe and you need to interpret these tracks that are exposed in a surface context, as a dynamic landscape.”

|This discovery puts the bow on the anamoly of Monte Verde, a housing compound at the tip of South America dated to at least 13,000, possibly 30,000 years ago.|
I studied Monte Verde as an anthropology major in the 1990s and it was controversial even then. Did not match the earliest lithic cultures then known in North America, so there was a lot of skepticism that the site really was that old, at the furthest terminus of the Western Hemisphere.
Now it is a yawner.

|Geez - and here I thought those Amish kids were acting up again...|
...it's not all innocence with those people............my sister who has worked in a public animal shelter for over 20 years apprised me of the Amish puppy mills in Pa.............says many are run under deplorable conditions.....she rarely will speak ill of anyone.....but goes off on this.

|U.S. confirms it will accept Canadian travellers with mixed vaccines|
Announcement follows weeks of speculation as new rules kick in Nov. 8

Canadians with mixed vaccines and U.S. travel plans can breathe a sigh of relief tonight.
Following weeks of speculation, the United States confirmed late Friday it will accept mixed vaccines when new rules kick in on Nov. 8 requiring that foreign travellers entering the U.S. be fully vaccinated.
Individuals inoculated with any combination of two doses of a COVID-19 vaccine authorized by U.S. regulators or the World Health Organization will be considered fully vaccinated, the U.S. Centers for Disease Control and Prevention (CDC) told CBC News.
WHO-approved vaccines include Moderna, Pfizer, AstraZeneca and its Indian-made counterpart, Covishield. So travellers with any combination of these vaccines will be allowed to enter the U.S.
The CDC does not recognize mixing COVID-19 vaccines but said it updated its guidance to reflect growing global acceptance of the practice.
"While CDC has not recommended mixing types of vaccine in a primary series, we recognize that this is increasingly common in other countries so should be accepted for the interpretation of vaccine records," CDC spokesperson Kristen Nordlund said in an email.

Millions of Canadians have mixed doses of COVID-19 vaccines. When the U.S. recently announced it would impose a vaccination requirement for travellers entering by both land and air, many Canadians with mixed doses worried they might soon be barred from entering the country.
"We felt kind of blindsided," said snowbird, Ingrid Whyte of Toronto. Following Canadian government guidance, she and her husband, John, each got one dose of Covishield and a second dose of Pfizer.
"We did everything that we were supposed to do in terms of getting vaccines," Whyte said.
The couple had booked a flight to Florida for Nov. 17, but cancelled it due to concerns over their mixed vaccines. They're now relieved to hear their vaccine combination won't be an issue when entering the U.S.
"We are thrilled," Whyte said. "I wish it could have been a little sooner. It would have allowed people to plan a little bit more effectively. But in the long run, it's great news."
It's also good news for Petar Sesar of London, Ont., who has a mix of Moderna and Pfizer.

Sesar's fiancée, Mara Bakula, lives in Cleveland. Sesar welcomed news this week that the U.S. land border will reopen on Nov. 8 to non-essential travellers, as he prefers to drive instead of fly to Cleveland.
However, he worried he might have no U.S. travel options come Nov. 8 if the country rejected his vaccine mix.
"That was a very scary moment," he said. "It felt like house arrest of sorts, like now I [may] have no option."
Earlier this year, the CDC stated online that a mix of two mNRA vaccines, Moderna and Pfizer, would be accepted in "exceptional situations." But Sesar didn't rest easy until he learned that the CDC had approved his exact combination.
"It is unbelievable," he said. "It is such a relief. I share the relief with millions of [Canadians]."
Where does the U.S. stand now on mixed vaccines?Canada updated its vaccination guidelines in June to recommend mixing COVID-19 vaccine doses based on emerging research that found it was both safe and effective.
Meanwhile, the CDC still maintains that "data on the safety and efficacy of a mixed-product series are limited."
But that could change.
The U.S. recently conducted a study exploring the effectiveness of using a different COVID-19 vaccine as a booster shot.
This week, U.S. authorities met to review the data which so far suggests mixing vaccines is safe and effective.

watch the two back to back.....5 years separate them
2016....media promotes false meme vs. the reality of the election
2021....media promotes false meme vs. the reality of the jab efficacy
......one false meme got Trump elected
......the second got many thousands killed
