Research on an arrangement of massive granite blocks in the Brazilian Amazon has indicated that they were used as an astronomical observatory about 1000 years ago.
After conducting radiocarbon testing and carrying out measurements during the winter solstice, scholars in the field of archaeoastronomy determined that an indigenous culture arranged the megaliths into an astronomical observatory about 1,000 years ago, or five centuries before the European conquest of the Americas began.
Their findings, along with other archaeological discoveries in Brazil in recent years — including giant land carvings, remains of fortified settlements and even complex road networks — are upending earlier views of archaeologists who argued that the Amazon had been relatively untouched by humans except for small, nomadic tribes.
I still remember reading Charles Mann’s piece in 2002 about the mounting evidence against the idea of a largely wild and pristine pair of continents civilized and tamed by Europeans.
Erickson and Balée belong to a cohort of scholars that has radically challenged conventional notions of what the Western Hemisphere was like before Columbus. When I went to high school, in the 1970s, I was taught that Indians came to the Americas across the Bering Strait about 12,000 years ago, that they lived for the most part in small, isolated groups, and that they had so little impact on their environment that even after millennia of habitation it remained mostly wilderness. My son picked up the same ideas at his schools. One way to summarize the views of people like Erickson and Balée would be to say that in their opinion this picture of Indian life is wrong in almost every aspect. Indians were here far longer than previously thought, these researchers believe, and in much greater numbers. And they were so successful at imposing their will on the landscape that in 1492 Columbus set foot in a hemisphere thoroughly dominated by humankind.
That article turned into 1491, which remains one of my favorite books.

Charles Mann’s 1491 is one of my all-time favorite books. I mean, if this description doesn’t stir you:
Contrary to what so many Americans learn in school, the pre-Columbian Indians were not sparsely settled in a pristine wilderness; rather, there were huge numbers of Indians who actively molded and influenced the land around them. The astonishing Aztec capital of Tenochtitlan had running water and immaculately clean streets, and was larger than any contemporary European city. Mexican cultures created corn in a specialized breeding process that it has been called man’s first feat of genetic engineering. Indeed, Indians were not living lightly on the land but were landscaping and manipulating their world in ways that we are only now beginning to understand. Challenging and surprising, this a transformative new look at a rich and fascinating world we only thought we knew.
On Twitter yesterday, Mann shared that a documentary series was being made based on the book. The eight-part series is being commissioned by Canada’s APTN (Aboriginal Peoples Television Network) and Barbara Hager, who is of Cree/Metis heritage, will write, direct, and produce.
This is fantastic news. I hope this gets US distribution at some point, even if it’s online-only.
One of the major points in Charles Mann’s 1491 (great book, a fave) is that the indigenous peoples of the Americas did not live in pristine wilderness. Through techniques like cultivation and controlled burning, they profoundly shaped their environments, from the forests of New England to the Amazon.
In the 1850s, the indigenous inhabitants of Yosemite Valley, who used controlled burning to maintain the health of the forest, were driven out by a militia. As Eric Michael Johnson writes in Scientific American, the belief in the myth of pristine wilderness by naturalist John Muir has had a negative impact on the biodiversity and the ability to prevent catastrophic fire damage in Yosemite National Park.
The results of this analysis were statistically significant (p < 0.01) and revealed that shade-tolerant species such as White fir and incense cedar had increased to such an extent that Yosemite Valley was now two times more densely packed than it had been in the nineteenth century. These smaller and more flammable trees had pushed out the shade-intolerant species, such as oak or pine, and reduced their numbers by half. After a century of fire suppression in the Yosemite Valley biodiversity had actually declined, trees were now 20 percent smaller, and the forest was more vulnerable to catastrophic fires than it had been before the U.S. Army and armed vigilantes expelled the native population.
As a belated recognition of Exploration Day, here’s Charles C. Mann’s piece on the history of the Americas before Columbus: 1491. This piece blew my doors off when I first read it.
Before it became the New World, the Western Hemisphere was vastly more populous and sophisticated than has been thought-an altogether more salubrious place to live at the time than, say, Europe. New evidence of both the extent of the population and its agricultural advancement leads to a remarkable conjecture: the Amazon rain forest may be largely a human artifact.
This article spawned a book of the same name, which is one of my favorite non-fiction reads of the past decade.
Tyler Cowen says that Charles Mann’s 1491 (a taste of which can be read here) is “one of my favorite books ever, in any field”, to which I add a hearty “me too”. Mann’s been hard at work at a sequel, 1493: Uncovering the New World Columbus Created, which is due out in August, just in time for some seriously awesome beach reading.
From the author of 1491 — the best-selling study of the pre-Columbian Americas — a deeply engaging new history that explores the most momentous biological event since the death of the dinosaurs.
More than 200 million years ago, geological forces split apart the continents. Isolated from each other, the two halves of the world developed totally different suites of plants and animals. Columbus’s voyages brought them back together — and marked the beginning of an extraordinary exchange of flora and fauna between Eurasia and the Americas. As Charles Mann shows, this global ecological tumult — the “Columbian Exchange” — underlies much of subsequent human history. Presenting the latest generation of research by scientists, Mann shows how the creation of this worldwide network of exchange fostered the rise of Europe, devastated imperial China, convulsed Africa, and for two centuries made Manila and Mexico City — where Asia, Europe, and the new frontier of the Americas dynamically interacted — the center of the world.
David Grann, the author of The Lost City of Z (which my wife scooped up off the bookshelf the other day and has barely put down since), reports on some new findings that indicate that there was a large civilization that lived in the jungles of the upper Amazon basin.
The latest discovery proves that we are only at the outset of this archeological revolution — one that is exploding our perceptions about what the Amazon and the Americas looked like before the arrival of Christopher Columbus. Parssinen and the other authors of the study in Antiquity write, “This hitherto unknown people constructed earthworks of precise geometric plan connected by straight orthogonal roads… The earthworks are shaped as perfect circles, rectangles and composite figures sculpted in the clay rich soils of Amazonia.”

Before European conquerers arrived, large areas of the Amazon River basin had been cleared away to make room for a network of towns and villages.
The findings raise big questions, says Susanna Hecht of the University of California in Los Angeles.
For starters, it forces a rethink of the long-held assumption that these parts of the Amazon were virtually empty before colonisation. What’s more, it shows that the large populations that did inhabit the region transformed the landscape.
“What we find is that what we think of as the primitive Amazon forest is not so primitive after all,” Heckenberger told New Scientist. “European colonialism wasted huge numbers of native peoples and cleared them off the land, so that the forest returned.”
I’m gonna plug 1491 again…the story above isn’t news to anyone who’s read this book, which argues that there was plenty going on in the New World before Columbus, et. al. arrived.
At PopTech a few weeks ago, Lester Brown, who has been a leading advocate of environmentally sustainable development for almost 30 years, spoke about the impact of the increasing production of ethanol. As more corn gets used for making automotive fuel, that reduces the amount of grain available for food production. As demand rises, so will the price…no matter what people are using the corn for, be it fuel or food. The countries that will really suffer in this scenario are those that import lots of grain for food.
When Brown said this, I immediately thought of Mexico. When you consider the food culture of Mexico, one of the first things to mind is corn. Corn (maize) was likely first domesticated in Mexico and remains the cornerstone of Mexican cuisine; in short, corn is far more Mexican than apple pie is American. In 1491, his excellent book on the pre-Columbian Americas, Charles Mann tells us that despite corn’s high status, Mexico is increasingly importing corn from the United States because it’s cheaper than local corn:
Modern hybrids are so productive that despite the distances involved US corporations can sell maize for less in Oaxaca than can [local farmer] Diaz Castellano. Landrace maize, he said, tastes better, but it is hard to find a way to make the quality pay off.
Those great tortillas you had at some local place while on vacation in Mexico? There’s an increasing chance they’re made from US corn. Mmm, globalizious! Of course, Mexican farmers are getting out of the farming business because they can’t compete with the heavily subsidized US corn and Mexico is losing control over one of their strongest cultural customs. Now that ethanol is changing the rules, there’s a bidding war brewing between Americans who want to fill their gas tanks and Mexicans who want to feed their children. Odds are the tanks stay fuller than the stomachs.
For reference, here’s what increasing ethanol production has done to the price of corn over the past three months:
And that’s despite a fantastic US corn harvest. The graph is from this article in the WSJ, which contains a quick overview of the effects that the growing ethanol industry might have.
