Archaeologists Find Italy's Earliest Wine—And It's Thousands of Years Older Than We Thought

Uncork a Barolo in honor of ancient traditions: Italians have been making wine for far longer than we thought. A new analysis of storage jars found in a cave in Sicily's Monte Kronio pushes back Italy’s wine-making history by thousands of years, as CNET alerts us.

Archaeologists from the University of South Florida and several Italian institutions report in Microchemical Journal that wine making in the region could date back as far as 3000 BCE. Previously, researchers studying ancient seeds hypothesized that Italy's wine production developed sometime between 1300 BCE and 1100 BCE.

Making grapes into wine has been a part of human history going back to the Stone Age. Georgians have been drinking wine for 8000 years. Grapevines spread through the Caucasus and the Middle East before making their way to Europe.

This new discovery was possible thanks to chemical analysis of unglazed clay pots found in a Monte Kronio cave. The Copper Age pottery still bore residue from the wine. The researchers were able to identify traces of tartaric acid and sodium salt left from the wine-making process. They're still working on figuring out whether it was red or white, though, as University of South Florida researchers explained in a press statement.

In 2013, archaeologists planted a vineyard and began making wine using ancient Roman techniques to see what wine actually tasted like in the Roman Empire. Foul as that wine may have been, it seems that Roman wine was the result of an even longer wine-making tradition than we knew.

Homo Erectus Might Have Been Really Lazy

Shipton et. al, PLOS ONE (2018)

Of all the human species that once roamed the world, only one remains—us. Why did our primitive cousins go extinct? For Homo erectus, something like laziness may have played a role, Cosmos reports.

A new study in the journal PLOS ONE explores the role that H. erectus's lack of drive may have contributed to its extinction. The international team of researchers based their analysis on an excavation of a paleolithic site in central Saudi Arabia, finding that the tools H. erectus made were of consistently lower quality than what tool makers in later periods used. Their tools were constructed with whatever material was easiest to get, rather than what would make the best tools.

And it wasn’t because better materials weren’t available. "At the site we looked at, there was a big rocky outcrop of quality stone just a short distance away up a small hill,” study co-author Ceri Shipton of the Australian National University said in a press release. “But rather than walk up the hill, they would just use whatever bits had rolled down and were lying at the bottom.” He added, “They knew it was there, but because they had enough adequate resources, they seem to have thought, ‘why bother?’”

Meanwhile, other hominin species, like our own Homo sapiens, were happily clambering up mountains to seek out better materials for their tools. Shipton suggests that H. erectus lacked the tendency toward exploration and curiosity that has helped our species thrive.

This “laziness,” combined with changes to their environment, was likely what did in H. erectus. As the humid environment around them became drier, H. erectus seemingly didn’t adapt: They didn't invent new kinds of tools to deal with the changing landscape, nor did they relocate or travel farther afield. The research team found the tools largely near dry river beds, suggesting that H. erectus neither progressed technologically nor modified their behavior for their altered habitat.

H. erectus did manage to walk upright as we do—a first in human evolution—and it was likely the first hominin to expand their habitat beyond Africa. But the combination of these two newly identified shortcomings may have contributed to H. erectus's demise.

Intriguing New Theory Might Explain the Fate of Easter Island's Civilization

Standing up to 33 feet high and weighing 81 tons, the huge moai statues of Easter Island (Rapa Nui) are the most recognizable artifacts of a thriving civilization that peaked at the middle of the last millennium. For hundreds of years, Polynesian peoples lived on the small island 2300 miles west of Chile and developed a complex culture. By the 1700s, when Europeans first arrived, much of the society was decimated.

For years, scientists thought they knew why—but fresh archaeological evidence has provided an alternative theory.

The Journal of Pacific Archaeology published a paper [PDF] this week contradicting the commonly held belief that, in the 1600s, Rapa Nui's inhabitants descended into a Lord of the Flies–like era of infighting and violence as a result of dwindling resources. According to new research, the island’s population may not have devolved into barbarism. Instead, they were collaborating on toolmaking.

University of Queensland archaeologist Dale Simpson, Jr. theorized that the raw materials used in the carving tools would reveal clues about the dynamics of the community. He and his colleagues collected 17 tools found near the moai, including axe-like toki. Using a mass spectrometer to analyze the chemical composition of the tools and samples from stone quarries on the island, Simpson and his colleagues found that most of the toki came from a single quarry.

Simpson believes this is evidence that Rapa Nui's people had not fallen into violent conflict, but were instead sharing resources—or at least allowing one another access to a favorite quarry for tool production. If the islanders were split into factions, it’s unlikely that whoever was controlling the quarry would permit rivals to make use of it.

If accurate, it would join other recent theories that are drawing a revised picture of Rapa Nui's civilization. Explorers once described a surplus of spear-like objects presumably used for combat, but modern researchers examining the tools (called mata’a) in 2015 found that their surfaces were too blunt to pierce skin and were probably used for tilling soil.

While Simpson's take on the newly discovered carving tools is an intriguing theory, researchers aren't ready to rewrite history just yet. Other scholars, including study co-author Jo Anne Van Tilburg, point out that raw materials for the tools could have been seized by force or some form of coercion.

More research will be needed to see if Simpson’s new theory holds up. If it does, it would present a new wrinkle in the storied history of Rapa Nui.
