700,000 year old “human” settlement in Qatar

Monday, June 23rd, 2008

After all of these years of reading reports of a find of tools, tombs, and old villages being found in Qatar and Bahrain, the news that early humans would have managed to find their way out of Africa to settle there is not much of a surprise, as it seems an almost obvious hotspot for activity. This does good for putting another point on the coastal migration routes. Then again, maybe their digs just get a lot of PR:

(UPI) — A prehistoric settlement in what is now Qatar could bear out different theories on emigration patterns from Africa, Danish archaeologists said.

Danish archaeologists report discovering a settlement they believe may be more 700,000 years old, The Copenhagen Post said.

Eight dwellings in the desert region of Qatar indicate that an early human species crossed what is now the Red Sea to leave Africa, the scientists said. The scientific community is uncertain about the routes early humans used to leave the continent.

The archaeologists said they only tentatively dated their find, having estimated the age from the types of artifacts — such as axes and knives — found at the site.

Other dating tests are necessary to confirm the estimates but the archaeologists said carbon-dating would be accurate only if organic material is found.

icebergs reached as far south as South Carolina 15,000 years ago

Monday, June 9th, 2008

Gouges found on the ocean floor reveal that icebergs reached as far south as South Carolina 15,000 years ago.

That could make it a lot easier to make a trans-Atlantic crossing at that time. Maybe this could relate to the proposals centered around the excavations of the Cactus Hill site in Virginia or the Topper site in South Carolina in some way. Has that Solutrean-Clovis hypothesis been completely discredited and discarded?

another Pacific coastal migration article

Sunday, June 1st, 2008

Just got around to reading the Discover article on Jon Erlandson’s research on Pacific coastal migration into the Americas. I didn’t see anything new since last time, but i gotta internalize the points of “following kelp forests” (or the “kelp highway”) and remembering the significance of San MIguel Island on an every day basis.

Also need to track down that reference to a Brazilian genetic study that would place the Pacific coastal migration in the Americas between 15,000 and 18,000 years ago. That doesn’t sound familiar.

more evidence for multiple waves from Asia to Americas

Saturday, May 31st, 2008

Again, no surprise. It’s just continuing the constant drip of evidence that there was no single group of people that populated all of the Americas.

Apparently the first people to colonize Greenland, the Saqqaq, were more closely related to certain groups found in Siberia, than to anyone else in North America.

pipeline work in Sakhalin reveals artifacts

Wednesday, April 23rd, 2008

Here’s the story:

YUZHNO-SAKHALINSK, April 18 (RIA Novosti) – Excavations along the route of a pipeline being built for a vast oil and gas project on Russia’s Far East island of Sakhalin have unearthed around 200 historic objects, a local historian said on Friday.

The head of the Sakhalin Region museum’s cultural heritage department, Igor Samarin, said the findings dated from the Lower Paleolithic period up to World War II, and include ancient settlements, military camps, battle sites, and artifacts of Russian and Japanese origin.

“Archaeology on Sakhalin has never seen field work on such a scale,” he said.

Between 2004 and 2007 archaeologists carried out excavation works on the 3,500 square meter area of the pipeline route, and made around 30,000 discoveries.

The pipeline is being built for the Sakhalin II project, controlled by Russia’s state natural gas giant Gazprom.

The findings included a Japanese fireproof pavilion used to keep a portrait of the emperor and his decrees. Archaeologists also discovered items belonging to the Soviet soldiers who fought in World War II.

The Soviet Union annexed the southern part of Sakhalin from Japan after WWII.

The sad thing is that it feels like a rush job, with so much material coming up so quickly that they don’t know what they are looking at. Lumping WW2 era artifacts in with Lower Paleolithic cannot be a good sign. Why would this even matter?

Sakhalin seems like a good site to find evidence of the Pacific coastal migration to the Americas. The Nivkh people seem like close cousins to the natives of the Pacific Northwest of North America. If there are microlithic tools being unearthed, they seem that they would require a more scrupulous investigation.

mtDNA in human coprolites in Oregon

Saturday, April 5th, 2008

Even though the Clovis First theory got smashed to bits years ago, every time there is a press release about anything dating before Clovis in the Americas, it’s the very first time all over again to the media. Nonetheless, the Oregon coprolites dating to 14,300 years ago is a welcome addition to the evidence against Clovis First… blah, blah, blah… Clovis wasn’t first. Get over it.

What’s cool about this story is the mitochondrial DNA being extracted from the coprolites (as well as examples of the diet of these people) and it is along the Pacific migration route. The abstract of the paper, DNA from Pre-Clovis Human Coprolites in Oregon, North America, states the mtDNA is from haplogroups A2 and B2.  The presence B haplogroup makes me wonder if that haplogroup primarily came to the Americas by the coastal route, and not overland through Canada, but it would be presumptuous and wrong for me to chime in too much more on that, as i don’t know much more than what has been absorbed from some popular science readings. Wild speculation is fun.

1.2 million year old human jawbone found in Spain

Wednesday, March 26th, 2008

The jawbone has been assigned as belonging to Homo antecessor for the time being, a hominid that would be a common ancestor to Homo sapien and Neandertals. Stone tools have been found before, dating from that period, but this appears to be the first bone from that time, in Europe. 

It’s not unexpected, but this is going to be cool.

Ket language family linked to Na-Dene language family

Monday, March 10th, 2008

It’s another link connecting Siberia to North America. The Ket language family is Siberian and Na-Dene is North American. Here it is:

ANCHORAGE, Alaska — A panel of respected linguists who met in Anchorage recently is hailing new research that links the Old World language of Ket to the sprawling New World family of Na-Dene languages.

Other than Siberian Yupik, a regional Eskimo dialect that straddles the Bering Strait, a connection between North American and Asian language families had never before been demonstrated.

The research by University of Western Washington linguist Edward Vajda, who spent 10 years deciphering the Ket language, drew upon parallel work by three Alaskans — Jeff Leer, Michael Krauss and James Kari, professors of linguistics at the University of Alaska Fairbanks — who independently detailed patterns in Na-Dene languages.

Establishing that two such far-distant language groups are closely related is both demanding and rare in the exacting field of historical linguistics, according to participants who attended a language symposium at the annual meeting of the Alaska Anthropological Association.

That Interior Indian languages spoken in North America are related to languages spoken in Asia has long been assumed, since other fields of science have widely concluded that the Americas weren’t populated until ice age hunters migrated across a temporary land bridge from the old world to the new world 10,000 to 12,000 years ago.

And as early as 1923, other linguists speculated specifically about a genetic link between the Yeniseic family of languages spoken along the Yenisei River (of which Ket is now the only surviving member) and the Na-Dene family, spoken in North America. Ten years ago, American linguist Merritt Ruhlen did so again after producing a list of 36 cognates — comparable words in two languages that sound alike and mean the same thing.

But producing lists of similar-sounding words isn’t sufficient evidence to establish a real genetic relationship between two languages, declared Bernard Comrie, a researcher at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, speaking at the Anchorage meeting.

That’s because cognates can also occur by accident or chance — when selective words are adopted by travelers from unrelated languages, or when words have a universal appeal.

What makes the new finding so exciting, Comrie said, is that it’s based on complex and verifiable morphologies that show how certain Ket words were systematically altered to create Athabascan words — or vice versa (the research doesn’t speculate on which language came first or when).

Vajda began studying the Ket language firsthand in the 1990s after the Iron Curtain fell and he began making field trips to the Yenisei River — about 3,600 miles west of Fairbanks.

“There is no road and no train,” Vajda said in an interview. “You have to go by steamboat or helicopter to get there.”

Through his research and interviews, Vajda determined that there are about 1,200 people who say they are Ket, including 200 people who speak the language. But only about 100 speak Ket fluently, Vajda said, and nearly all of them are now older than 50.

“They were the last hunters of north Asia that didn’t have any domesticated animals that they used for food,” he said. “They moved around, they didn’t live in the same place.”

That came to an end when the Stalin regime in the Soviet Union forced the Ket to live in villages. Now their traditional lifestyle is nearly gone, Vajda said — and their language is disappearing too.

While trying to capture it before it vanishes altogether, Vajda gained a new understanding about the peculiarities of Ket verbs, suffixes and tonalities — which are unlike any of the other Siberian languages to the east.

Comparing what he learned with research conducted independently in Alaska, Vajda began to find words the two languages had in common. A news release issued this week by the Alaska Native Language Center at the University of Alaska-Fairbanks, concurs, noting language similarities “too numerous and displaying too many idiosyncratic parallels to be explained by anything other than common descent.”

Among linguistic scholars elsewhere who have reviewed Vajda’s paper in its draft form and reacted favorably so far is Heinrich Werner of Bonn, Germany — a world authority in the Ket language, whose work Vajda cited and incorporated into his own, along with that of the Alaskans.

Vajda thinks his research might be a door-opener for scientists in other fields, including those who work in human genetics and archaeology, to proceed with additional comparisons of the two cultures.

He says it also points out the necessity and urgency to record dying languages before they disappear.

Linguistics is obviously not my thing. I’m a sloppy amateur in everything. However, in looking at the distribution map of of Na-Dene, it was interesting to see that Navajo not just belongs to that family, but is significantly isolated from the rest of the family. The story of how that happened is bound to be interesting.

using obsidian’s origin to track human migration in Pacific Northwest

Sunday, March 9th, 2008

This practice of studying movement of tribes by where their obsidian came from seems cool to me. Obsidian is identifiable by its volcano of origins. The migration of north to south versus west and east is almost too obvious, as that’s the way that the mountain ranges run, but it’s obviously better than asserting with less evidence. I was hoping more about trade routes would be uncovered, but until obsidian from areas further away is tested, that won’t become clear:

A long time ago – a very long time ago – obsidian was all the rage. Abundant in Oregon and relatively easy to craft, Native American cultures used the volcanic rock to make prehistoric tools: knives, spear tips and the like.

“They’re razor sharp, sharper than any steel could be ground,” said Dennis L. Jenkins, Ph.D., senior staff archaeologist at the University of Oregon, who presented Friday at Tamastslikt Cultural Institute.

In his lecture, entitled “Obsidian: History Through the Volcanic Glass Window,” Jenkins touched on the wealth of information contained in the rock artifacts found all over the state, and how archaeologists can trace the movement of those artifacts from their original source.

“There will be these rare minerals in there that can be chemically identified, and they are unique to each volcano,” Jenkins said.

By a special X-ray procedure archaeologists can match the mineral composition to a specific volcanic source in the Western United States.

“And that allows us to track each individual artifact back to the exact location where it came from,” he said. “And it’s not uncommon in a particular site to find up to 30 or 40 obsidian sources represented there.”

Furthermore, archaeologists can trace the movement of obsidian artifacts by a fairly simple process. Whereas ancient peoples who crafted the tools would begin with large, often fist-sized cores, they would break them down, leaving millions of tiny flake pieces at the source location.

But the tools themselves would get smaller and smaller through time as their owners traveled and sharpened them, leaving further trails of flakes. Thus, as a general rule, Jenkins said the smaller the artifact, the farther it is from the original source.

“They were leaving a trail of evidence behind them,” he said.

For figuring out the age of the artifacts, Jenkins described multiple dating techniques, including a process called obsidian hydration.

As obsidian naturally absorbs water from the atmosphere, archaeologists can measure the amount of absorption and determine the time it took to occur. They first, however, must calibrate that measurement to the average soil temperature of the location where it was found.

Alternately, through a method called seriation, archaeologists sometimes can guess the general date of an obsidian tool based on its appearance.

“Technology improved through time,” Jenkins said, showing slides of increasingly sophisticated tools.

While ancient hunters may have begun by crafting relatively oval-shaped tools around 13,500 years ago, by about 2,000 years ago they were able to make extremely swift-moving arrow points.

Jenkins concluded by demonstrating the results of a study he helped conduct, examining the source and age of about 5,600 obsidian artifacts in Oregon. What he found were a few general pattern areas in which obsidian artifacts traveled with their owners north and south, with little east to west movement from the source. Jenkins presented a few ideas for that pattern, saying valleys more or less corresponded with the boundaries.

“Maybe this is a product of just normal movement through the environment on a north-south access,” Jenkins said.

Also, as old storm patterns would have moved west to east, the ancient cultures may have migrated north and south, carrying their resources along the way.

Caral now dated as oldest urban site in Americas

Wednesday, February 27th, 2008

Or not. Looking at that story about Patiti, this claim could be refuted in a month or two, but the research seems far more solid here.

The Caral site in Peru has been dated at 3,500 BC,  contemporaneous with urban sites in Mesopotamia and Egypt (and India too, i reckon.) Here’s the AP article:

LIMA, Peru (AP) — A team of German and Peruvian archaeologists say they have discovered the oldest known monument in Peru: a 5,500-year-old ceremonial plaza near Peru’s north-central coast.

Carbon dating of material from the site revealed it was built between 3500 B.C. and 3000 B.C., Peter Fuchs, a German archaeologist who headed the excavation team, told The Associated Press by telephone Monday.

The discovery is further evidence that civilization thrived in Peru at the same time as it did in what is now the Middle East and South Asia, said Ruth Shady, a prominent Peruvian archaeologist who led the team that discovered the ancient city of Caral in 2001. Shady serves as a senior adviser to Peru’s National Culture Institute and was not involved in the project.

The find also raises questions about what prompted “civilizations to form throughout the planet at more or less the same time,” Shady said.

The circular, sunken plaza, built of stones and adobe, is part of the Sechin Bajo archaeological complex in Andes foothills, 206 miles northwest of Lima, where Fuchs and fellow German archaeologist Renate Patzschke have been working since 1992.

It predates similar monuments and plazas found in Caral, which nonetheless remains the oldest known city in the Americas dating back to 2627 B.C.

The plaza served as a social and ritual space where ancient peoples celebrated their “thoughts about the world, their place within it, and images of their world and themselves,” Fuchs said.

In an adjacent structure, built around 1800 B.C., Fuchs’ team uncovered a 3,600-year-old adobe frieze — six feet tall — depicting the iconic image of a human sacrificer “standing with open arms, holding a ritual knife in one hand and a human head in the other,” Fuchs said.

The mythic image was also found in the celebrated Moche Lords of Sipan tombs, discovered on Peru’s northern coast in the late 1980s.

Walter Alva, the Peruvian archaeologist who uncovered the Lords of Sipan tombs, said the plaza found in Fuchs’ dig was probably utilized by an advanced civilization with economic stability, a necessary condition to construct such a ceremonial site.

The excavation was the fourth in a series of digs at the Sechin Bajo complex that Fuchs and Patzschke began on behalf of the University of Berlin in 1992. Deutsche Forschung Gemeinschaft, a German state agency created to sponsor scientific investigations, has financed the most recent three digs.

The find “shows the world that in America too, human beings of the New World had the same capacity to create civilization as those in the Old World,” Shady said.

Her discovery, Caral, made headlines in 2001 when researchers carbon-dated material from the city back to 2627 B.C., proving that a complex urban center in the Americas thrived as a contemporary to ancient Mesopotamia and Egypt — 1,500 years earlier than previously believed.

It’s rather interesting that this early urban site is in South America, but nothing analogous has turned up in North America. Were the remnants of early civilization destroyed so thoroughly in European colonization? Yeah, probably… It seems a little odd that humans would have colonized both continents, yet first became urbanized much further geographically from where they appeared. Then again, it might not just be about the European colonization, but subsequent waves from Asia that disrupted the established cultures in North america.
