Archeologists are disputing the age of a jawbone found in a cave in England.

The uncertainty of science: Archeologists are disputing the age of a jawbone found in a cave in England.

Both sides of the debate agree that there is a lot riding on the outcome. “What is at stake is the entire [prehistory] of Neandertals and early modern humans in Europe,” Pettitt says. Apart from the Kents Cavern fossil and some 43,000- to 45,000-year-old teeth from Italy whose status as modern human or Neandertal is currently also debated, the oldest undisputed human fossils in Europe are about only 40,000 years old and come from a site in Romania. If modern humans really made it all the way to northwest Europe by 41,500 years ago or even earlier, it would mean that they entered Europe much earlier than once thought and also spread across the continent very rapidly. It would also increase the overlap between modern humans and the Neandertals, who already lived in Europe, and who went extinct sometime between 40,000 and 35,000 years ago. What’s more, such an overlap could make it more likely that Neandertals, who made sophisticated ornaments and tools in their last years, copied these techniques from modern humans rather than inventing them on their own.

A failed public works project — from the year 1350 AD

Casa Grande

Yesterday my wife Diane and I took my 94-year-old mother on a sightseeing trip to see the Casa Grande ruins southeast of Phoenix, “the largest known structure left of the Ancestral People of the Sonoran Desert.”

This four story high structure was built around 1350 AD from bricks made of concrete-like caliche mud, with the floors and roofs supported by beams of pine, fir, and juniper brought from as far away as fifty miles. (The rooflike structure above the ruins was built by the National Park Service in order to protect it from rain.)

Though impressive, I must admit I’ve seen far more impressive American Indian ruins elsewhere. Casa Grande, which means “Great House” in Spanish, suffered as a tourist attraction from two faults:

An Indian tribe has sued and three researchers have countersued over possession of two 10,000-year-old skeletons unearthed during construction in San Diego.

Fighting over bones: An Indian tribe has sued and three researchers have counter-sued over possession of two 10,000-year-old skeletons unearthed during construction in San Diego.

Not surprisingly, the problem here stems from a poorly written federal law amended by a bureaucratic rule in 2010 that gives any Indian tribe control over any ancient human bones found in the U.S., even if those bones come from a human that lived long before the tribe even existed.

A special issue from Nature: Peopling the planet.

A special issue from Nature: Peopling the planet.

I haven’t yet had time to read this special issue, but it will certainly be fascinating, as it apparently summarizes the most current knowledge scientists have about the manner and timing of the human migration of the entire surface of the Earth. Overall, it appears that this migration took place sooner and faster than previously believed. Definitely worth a read.

Have researchers found Leonardo da Vinci’s lost “The Battle of Anghiari” fresco, hidden for the past six centuries behind a wall?

Have researchers found Leonardo da Vinca’s lost “The Battle of Anghiari” fresco, hidden for the past six centuries behind a wall?

The painting, considered a masterpiece by contemporaries, had never been finished by da Vinci because he had used an experimental technique to paint it, and that technique had failed. Thus, the painting was painted over fifty years later. The only reason we have a good idea of what the painting looked like is that several artists were so impressed by it that they produced copies while it was still visible.

The research suggests the painting was not painted over, but that a false wall was built in front of it. If so, this would be truly exciting discovery. The painting would probably not be in very good shape, but to actually see it would be wonderful.

New evidence suggests that Stone Age hunters from Europe reached the New World ten thousand years before their Asian counterparts.

New evidence suggests that Stone Age hunters from Europe reached the New World ten thousand years before their Asian counterparts.

A remarkable series of several dozen European-style stone tools, dating back between 19,000 and 26,000 years, have been discovered at six locations along the US east coast. Three of the sites are on the Delmarva Peninsular in Maryland, discovered by archaeologist Dr Darrin Lowery of the University of Delaware. One is in Pennsylvania and another in Virginia. A sixth was discovered by scallop-dredging fishermen on the seabed 60 miles from the Virginian coast on what, in prehistoric times, would have been dry land. …

What’s more, chemical analysis carried out last year on a European-style stone knife found in Virginia back in 1971 revealed that it was made of French-originating flint.

None of this is really surprising. Once we humans became the creatures we are, it became second nature for us to spread out quickly across the globe. In the case of these first European settlers, however, they came in too small numbers, and were thus eventually overwhelmed by the later settlers coming from Asia.

Scouring the Aegean Sea for the world’s oldest shipwrecks.

Scouring the Aegean Sea for the world’s oldest shipwrecks.

A Bronze Age wreck called Ulu Burun shows how the remains of a single ship can transform archaeologists’ understanding of an era. Discovered in 1982, it lies about 9 kilometres southeast of Kaş in southern Turkey, and dates from around 1300 BC, a century or two after the Minoans disappeared.

Christos Agourides, secretary-general of the Hellenic Institute of Marine Archaeology in Athens, describes it as “the dream of every marine archaeologist”. It took ten years to excavate, and researchers are still studying the nearly 17 tonnes of treasures recovered. The vast cargo includes ebony, ivory, ostrich eggs, resin, spices, weapons, jewellery and textiles as well as ingots of copper, tin and glass.

But what really stunned archaeologists was that the artefacts on this one vessel came from at least 11 different cultures1 — from a gold scarab bearing the name of the Egyptian queen Nefertiti to copper from Cyprus and tin from central Asia.

The wreck provided tangible evidence of an astonishing array of contacts and trade between the different cultures of the Mediterranean and Near East in the late Bronze Age. The Ulu Burun ship sailed at around the time that Tutankhamun ruled Egypt, and “it is far more important than Tutankhamun’s tomb as a contribution to our understanding of the period”, according to Wachsmann. “This goes to the nitty gritty of the world. It’s Wall Street in a ship.”

Newfound treasures at an archeological dig in Panama have provided scientists with the best clues yet about an unnamed tribal culture that had trived in the centuries just prior to the arrival of the Spaniards.

Newfound treasures at an archeological dig in Panama have provided scientists with the best clues yet about an unnamed tribal culture that had thrived in the centuries just prior to the arrival of the Spaniards.

The most recent dig, in early 2011, uncovered a similarly adorned chief in a multilevel burial pit once sheltered by a wooden roof. Surrounding this golden chief are at least 25 carefully arranged bodies, making the assemblage the largest of the six El Caño burials revealed to date. … Among the corpses golden attire for a child, possibly the chief’s son: tiny gold plates, bracelets, earrings, and a necklace of semiprecious stones. At the bottom of the pit, the chief himself was supported by a sort of platform created from the tight arrangement of 15 bodies. Mayo believes those individuals could be war captives or slaves who were sacrificed or committed suicide.
