I weep for the future

According to this CNN story, an “inventor” in Los Angeles claims to have an electric motor that produces more electricity than it consumes. He wants to sell some unpublished photos of Michael Jackson to finance development. I can’t tell from the article whether he’s a scammer, or just an idiot who flunked junior high physics. Given the straightforward way the story is written, I have to assume the latter applies to the reporter, at least.

Apart from the scientific impossibility, simple common sense says that if he had invented a miracle machine that produces electricity for free, he wouldn’t need to raise any money to develop it. He could walk in the front door of any big utility company and walk out a billionaire.

That said, it’s not the article itself but some of the comments that really make me want to bang my head against the desk. And then pray that those commenters forget to mark election day on their calendars.

Oldest mine in the Americas

It looks like the article is not available online yet, so all I have to go on is this press release. Basically, iron oxide was being mined as a pigment in Chile as far back as 12,000 years ago. It doesn’t say if that date is calibrated or uncalibrated, but either way it’s a pretty impressive date for early mining, especially so far south.

It’s about time the CDC finally started taking this threat seriously.

Reading old ethnographies

For fun recently, I’ve been reading Isabel Kelly’s 1932 Ethnography of the Surprise Valley Paiute (yes, I’m aware that I have strange tastes in reading). In the late 19th and early 20th centuries, both amateur and professional anthropologists raced to document the cultures of what were considered to be “vanishing races.” Most of those peoples, obviously, did not vanish. Instead, they adapted to new circumstances, just as people have been doing throughout human history. The anthropological work of that era, however, has nevertheless proved in many cases to be invaluable, in that it gathered and preserved cultural information at a time when many indigenous peoples were under tremendous pressure to abandon their traditions and assimilate completely into American society.

Most of this work was not the “participant observation” that we tend to think of as stereotypical anthropology; where the scientist goes to live among an unfamiliar group of people, observing and taking notes on their day-to-day activities. Rather, anthropologists like Alfred Kroeber, John Peabody Harrington, and Isabel Kelly conducted extensive interviews with people old enough to remember the ways in which people had lived half a century or more earlier.

Apart from simply being fascinating to read, much of this material, if carefully used, is also invaluable to an archaeologist. One of the biggest caveats, or course, is time. In most cases, the interviews were conducted late enough that the informants would have had no personal memory of any time before contact with Europeans; they were born into societies that had already undergone profound changes. And, of course, these were human beings and not computers. They did not have perfect recall of events they had experienced decades earlier. It should also be considered that some informants may not have been completely forthcoming with information they considered private, and that some of what they reported might have been misunderstood by the anthropologist. But even after these and other limitations have been taken into account, these early ethnographies are often very helpful in interpreting what remains in the archaeological record, particularly from period shortly after European contact.

But mainly, I read old ethnographies because I enjoy it. They provide a fascinating glimpse into the past as it was actually experienced by some of the people who lived it.

The rules of language are innate… unless they’re not

A study just published by a team of cognitive scientists at Johns Hopkins University has found evidence that humans are born with an innate sense of syntactical rules that makes it easier for us to learn languages. The findings are based on an experiment involving teaching groups of people various artificial languages that differ from one another only in certain grammatical rules.

What makes this finding particularly interesting is that just a little over a year ago a team at the Max Planck Institute found evidence that syntactical rules in languages evolve from each language’s unique historical context, and not from anything innate in the human brain.

And on the gripping hand, there was also a study published last June by Dr. Paul Kiparsky of Stanford University in which he found evidence that language change over time seems to follow universal principles.

I’m not a linguistic anthropologist, much less a formal linguist, and I certainly don’t understand the subject well enough to critique any of these papers. However, the question of whether or not universal language structures are innate to the human brain (as Noam Chomsky proposed almost 50 years ago) is a truly fascinating one, and I’m looking forward to seeing how the debate will continue to evolve.

The first Americans

A recent article in the Daily Mail reports that genetic testing has indicated that the first group to reach North American may have numbered around seventy people. I’m always happy to see the press reporting on archaeological matters, but I have to admit I’ve got some reservations about this story.

My first question is why the Mail is publishing this as “stunning new” research when the study they refer to, by Dr. Jody Hey of Rutgers University, was published in 2005. There’s a download link for the paper, titled On the Number of New World Founders: A Population Genetic Portrait of the Peopling of the Americas, on Dr. Hey’s web site. I don’t have the background in genetics to critique the work, but I will note, as Dr. Hey himself does, that the date he came up with for the initial entry into North America is somewhat younger than is suggested by archaeological evidence.

I admit I am a little puzzled by Hey’s choice to sample people who spoke Amerind languages. The Amerind family, proposed more than twenty years ago by Joseph Greenberg, has never been widely accepted by linguists specializing in North American languages. In other words, there are no linguistic grounds for thinking that the people Hey studied are all descendents of the same group of early migrants, although that possibility certainly not ruled out.

Beyond all this, the Daily Mail then goes on to claim that, “the accepted wisdom among archaeologists is that the first people to colonise America were called the Clovis.” This, of course, has not been true for some time now. I’m not sure where this error originated, but it didn’t come from Dr. Hey, who mentions the pre-Clovis Monte Verde site in his paper. New evidence since 2005, including the incredible find of human coprolites at Paisley Cave, have placed the pre-Clovis occupation on even firmer ground. It appears that the reporter at the Mail neglected to do even the most basic homework. Like checking Wikipedia. Or even reading Dr. Hey’s paper before writing a story about it.

The First Amendment

It was apparently one of the things damaged by the recent tornadoes. According to the Times Free Press, reporters in Chattanooga are being threatened with arrest for photographing storm damage and clean-up work.

Giants in the Earth

I stumbled on this in an autobiography of Buffalo Bill Cody (p. 207):

AN INTERESTING TRADITION

While we were in the Sand Hills, scouting the Niobrara country, the Pawnee Indians brought into camp, one night, some very large bones, one of which a surgeon of the expedition pronounced to be the thigh bone of a human being. The Indians claimed that the bones they had found were those of a person belonging to a race of people who a long time ago lived in this country: That there was once a race of men on the earth whose size was about three times that of an ordinary man, and they were so swift and powerful that they could run alongside of a buffalo, and taking the animal in one arm could tear off a leg and eat the meat as they walked. These giants denied the existence of a Great Spirit, and when they heard the thunder or saw the lightning they laughed at it and said they were greater than either. This so displeased the Great Spirit that he caused a great rain storm to come, and the water kept rising higher and higher so that it drove those proud and conceited giants from the low grounds to the hills, and thence to the mountains, but at last even the mountain tops were submerged, and then those mammoth men were all drowned. After the flood had subsided, the Great Spirit came to the conclusion that he had made man too large and powerful, and that he would therefore correct the mistake by creating a race of men of smaller size and less strength. This is the reason, say the Indians, that modern men are small and not like the giants of old, and they claim that this story is a matter of Indian history, which has been handed down among them from time immemorial

As we had no wagons with us at the time this large and heavy bone was found, we were obliged to leave it.

With nothing further to go on, I have to assume for the moment that Buffalo Bill is telling the truth, and that his account should be taken at face value: The party was shown some very large bones, one of which the surgeon thought was human, and one or more Pawnee Indians related the story that is given here. Throughout the nineteenth century, newspaper account record a great many hoaxes involving giant skeletons, or sometimes mummies, but I have no evidence that this particular case involves any deception, either on the part of Buffalo Bill or that of his Pawnee informants.

As the bone was not kept, there is obviously no way now to determine it’s actual origin. Very likely it came from some species of extinct megafauna that could not be readily identified by either the Indians or the Buffalo Bill party. There are a number of conditions under which organic material such as bone can be preserved for many thousands of years. It was probably not a fossil, that is, a mineralized bone, since it is hardly likely that the fact that the object was made out of rock instead of bone would have been overlooked.

Giants, of course, are found in the traditions of an enormous number of cultures, from every part of the world. The same is true of world-destroying floods. In this case the two motifs are explicitly connected, with the giants all drowning during the flood. This juxtaposition is far also from unique, appearing in traditions as widely removed from one another as Chumash and Hebrew.

I’m afraid I don’t know enough about the Pawnee to speculate as to how this story connects to other narratives, or what role it may have played in Pawnee culture. Most of the ethnographic information I’ve studied comes from peoples west of the Rocky Mountains; in California, the Great Basin, or the Southwest. Timothy Pauketat has argued* that at least some nineteenth century Pawnee religious rituals might have been derived from practices carried out at Cahokia, but I can’t say what relevance, if any, that connection might have for this story.

Since there is no indication that this story has any particular religious significance, I would tentatively classify it as an example of what I’ve been calling fantastic ethnobiology: cultural information regarding plants, animals, and intelligent beings that do not exist in nature, and which are not functioning in a religious context. (Yes, I know there are some problems with this definition, but it’s the best one I’ve got at the moment. I’ll go into it in more detail in a future blog post.)

As I said, I only stumbled on this account by accident. It’s from a culture that’s outside my area of limited expertise, but I nevertheless found it interesting enough to be worth thinking about.

Visiting the asteroid belt

While most of the world’s attention has been occupied with other matters, a spaceship with an advanced ion propulsion system has been quietly approaching Vesta, the second largest object in the asteroid belt. Launched in 2007, the spacecraft named Dawn is scheduled to arrive at Vesta in July of this year. After orbiting Vesta for a year, Dawn will move on to the dwarf planet Ceres in order to investigate that body as well. If it works, it will be the first time a space probe has ever entered orbit around one world, and then left it to visit another. All previous multi-body space missions have been quick flybys.

Yesterday Dawn began to navigate by tracking Vesta with its own camera; prior to that it had relied on radio signals from Earth. Space.com has the story, complete with pictures of both Vesta and Dawn.

What makes this seem rather weird to me is that I can still remember the original Star Trek episode Spock’s Brain, in which Scotty stated that ion propulsion was significantly more advanced than the antimatter-powered warp engines the Enterprise used.
