Yup wrote that when I was tired. My bad."Even so the very earliest reliable dates are still much earlier than Australia. 20,000 years compared to 50 or more.
Genetics bear this out too."
Later...?
No worries Shadowsot - she'll be right.Yup wrote that when I was tired. My bad.
I'm not clear on this. Have they dated the sloth remains or are they basing this on the assumed date of sloth extinction? If the latter then it may be be evidence of the survivial of giant sloths.Where did these people come from?
The date that humans arrived in South America has been pushed back to at least 25,000 years ago, based on an unlikely source: bones from an extinct giant ground sloth that were crafted into pendants by ancient people.
Discovered in the Santa Elina rock shelter in central Brazil, three sloth osteoderms — bony deposits that form a kind of protective armor over the skin of animals such as armadillos — found near stone tools sported tiny holes that only humans could have made.
The finding is among the earliest evidence for humans in the Americas, according to a paper published Wednesday (July 12) in the journal

The Santa Elina rock shelter, located in the Mato Grosso state in central Brazil, has been studied by archaeologists since 1985. Previous research at the site noted the presence of more than 1,000 individual figures and signs drawn on the walls, hundreds of stone tool artifacts, and thousands of sloth osteoderms, with three of the osteoderms showing evidence of human-created drill holes.
The newly published study documents these sloth osteoderms in exquisite detail to show that it is extremely unlikely that the holes in the bones were made naturally, with the implication that these bones push back the date humans settled in Brazil to 25,000 to 27,000 years ago. These dates are significant because of the growing — but still controversial — evidence for very early human occupation in South America, such as a date of 22,000 years ago for the Toca da Tira Peia rock shelter in eastern Brazil.
Using a combination of microscopic and macroscopic visualization techniques, the team discovered that the osteoderms, and even their tiny holes, had been polished, and noted traces of stone tool incisions and scraping marks on the artifacts. Animal-made bite marks on all three osteoderms led them to exclude rodents as the creators of the holes.
"These observations show that these three osteoderms were modified by humans into artefacts, probably personal ornaments," the researchers wrote in their paper.

Ah, missed that, I'll blame it on being old and feeble minded. It's getting harder now for the late arrival lot to maintain their position.it seems to relate to the geological layers.
The presence of human-modified sloth bones in association with stone tools from geological layers that date to 25,000 to 27,000 years ago is strong evidence that people arrived in South America far earlier than previously assumed.
Caution should always be observed, but this looks much more solid than some of the other claims recently. I'm excited.Where did these people come from?

I've always thought RaymonM, that our language indicates our historical trek (so to speak). This is confirmation.Siberian origins of Indigenous North American Languages.
Johanna Nichols, a linguist at the University of California, Berkeley, has used her pioneering work in the field of language history to learn more about language development in North America. She has found that it can be traced back to two language groups that originated in Siberia. Her paper is published in the American Journal of Biological Anthropology.
Over the past several decades, scientists have learned more about the people who originally populated North America, and by extension, Central and South America. One characteristic of these people has remained largely a mystery: the evolution of the languages spoken by people living in what is now Canada, the U.S. and Mexico.
For this new study, Nichols used statistical techniques she developed to trace language lineage back to the earliest inhabitants of North America, going back 24,000 years.
Nichols' techniques involve the use of linguistic typology, a field that involves comparing languages and organizing them based on shared criteria. To learn more about early North American languages, she compiled lists of language characteristics and applied them to all known languages. She then scored each of the languages based on the revealed qualities. This allowed her to compare the languages as a way to find resemblances among them and spot patterns.
Nichols found that she could trace the languages spoken in early North America back to just two lineages, both of which originated in Siberia. They came, she notes, with the people who made their way across land bridges during Ice Age glaciation events. ...

I've long been curious about that one.Mesoamerican Evidence of Precolumbian Transoceanic Contacts
In this article we discuss the results of the re-examination of a terracotta head of supposed Roman origin found in a pre-Hispanic burial offering near Mexico City. A thermoluminescent age test performed in 1995 at the Forschungsstelle Archaometrie in Heidelberg, Germany, set the age limits of the artifact at 1780 ± 400 B.P., which is consistent with the Roman-origin hypothesis.
A review of the circumstances of this discovery did not demonstrate any sign of possible post-Columbian intrusion and permits the acceptance of the object as the first hard evidence from Mesoamerica to support pre-Hispanic transoceanic contacts between the Old and New Worlds.
