  • Paleo and "physical culture" movements

    Sat, 2013-05-04 12:01 -- John Hawks

    NPR has a short piece with an interesting historical story about old-time back-to-nature fitness fanatics: "Paleo Diet Echoes Physical Culture Movement Of Yesteryear"

    As Hamilton Stapell, a historian at the State University of New York, New Paltz, found when he went digging into the archives of physical culture, there are striking resemblances to the paleo movement today. And, he argues, this shows that people seem to romanticize a healthier past in the midst of great societal upheaval: the Industrial Revolution, in the case of physical culture; and the digital revolution, in the case of paleo.

    I don't think this specific link is very persuasive, there have been "go back to the good old days" movements since the dawn of time. Most of them have had no basis in anthropological science.

  • Boning up on British history

    Tue, 2013-04-30 09:10 -- John Hawks

    From The Guardian: "Richard III archaeologists to return to Leicester site in search of lost knight".

    This time the team is applying to the Home Office for an exhumation licence for a lead-lined stone sarcophagus, which they believe holds the undisturbed remains of Sir William Moton, believed to have been buried at Grey Friars in 1362.

    ...

    The original dig was funded by the Richard III Society, but the next phase will be paid for by the university and city council, which is predicting a tourism bonanza from the discovery.

    My rule of thumb: When British people are doing something ghoulish because they predict a "tourism bonanza", look around for a blue police box.

  • Alfred, possibly not under a car park

    Fri, 2013-03-29 21:08 -- John Hawks

    So after they found the bones of Richard III under a parking lot, now everybody is apparently going crazy to dig up bones under parking lots, churchyards, unmarked graves, wherever.

    Now we hear that churches and institutions that have bones under their parking lots are digging them up to prevent forensic anthropologists from doing it first: 'Alfred the Great' bones exhumed from unmarked grave".

    His body was first buried near Winchester Cathedral, moved at least once there, then moved again to Hyde Abbey in a great procession in 1110. As in Leicester, that church was destroyed in the dissolution of the monasteries, and his remains too were assumed to lie under a modern car park which had previously been the site of a prison. In 1999 there was great excitement when archaeologists found the foundations of abbey buildings, and then human bone – but it proved to be that of an elderly woman who had suffered from painful arthritis.

    Here, they have a body from an unmarked grave in a cemetery that they believe to be Alfred's. They've dug it up as a prophylactic against digging it up. Or something.

    Does England have any parking lots without bodies under them? Can the ghosts of medieval monarchs turn your Lancia into another Christine? Is there any chance that these bones won't be subjected to forensic study leading to another TV show?

    By the way, the most interesting use of genetics here would be to get a whole genome and make an estimate of the proportion of ancestry of common Britons that come from the royal family 1000 years ago...

  • Scholarship and experience outside the academy

    Thu, 2013-02-07 11:27 -- John Hawks

    The Wall Street Journal has an inspiring story of a hairdresser who turned her curiosity about Roman hairstyles into novel scholarship: "On Pins and Needles: Stylist Turns Ancient Hairdo Debate on Its Head".

    In 2007, she sent her findings to the Journal of Roman Archaeology. "It's amazing how much chutzpah you have when you have no idea what you're doing," she says. "I don't write scholarly material. I'm a hairdresser."

    John Humphrey, the journal's editor, was intrigued. "I could tell even from the first version that it was a very serious piece of experimental archaeology which no scholar who was not a hairdresser—in other words, no scholar—would have been able to write," he says.

    Ms. Stephens' article was edited and published in 2008, under the headline "Ancient Roman Hairdressing: On (Hair)Pins and Needles." The only other article by a nonarchaeologist that Mr. Humphrey can recall publishing in the journal's 25-year history was written by a soldier who had discovered an unknown Roman fort in Iraq.

    There is so much room in archaeology for people with deep subject knowledge, but not necessarily archaeological training, to make original contributions. Last night's NOVA episode, with a group of people trying to reconstruct Egyptian chariots, is another case where an ancient tradition can only be examined by those with insights about the subject beyond the historical and archaeological record -- in this instance, how to get a team of horses to work together using bridles, bits and yokes that no one had seen used in more than 2000 years.

    One of the great potential strengths of online media and open access is to enable this kind of participation by non-academicians. I'm hoping to capture some of that enthusiasm and knowledge in an upcoming project.

  • Unexpected "Radium Age" stories

    Sun, 2012-09-23 14:55 -- John Hawks

    I was enjoying a Nature discussion of "radium age" sci-fi literature, when this line caught me by surprise:

    In Jack London's post-apocalyptic The Scarlet Plague (1912), a race of barbarians descended from San Francisco's brutalized underclass roam the city's devastated remains after the fatal pandemic of 2013.

    Wait a minute, Jack London wrote a zombie story?

    Well, it's more Postman than zombies, but it's available on the Kindle for 99 cents: The Scarlet Plague (Annotated - Includes Essay and Biography). (UPDATE 2012-09-23: A reader notes that the story is also available for free from Project Gutenberg: http://www.gutenberg.org/ebooks/21970).

    Here's the description:

    The story takes place in 2073, sixty years after an uncontrollable epidemic, the Red Death, has depopulated the planet. James Howard Smith is one of the few survivors of the pre-plague era left alive in the San Francisco area, and as he realizes his time grows short, he tries to impart the value of knowledge and wisdom to his grandsons.

    They've apparently reverted to a Stone Age lifestyle, which does explain the Jack London element. I also love discovering that When the World Shook was written by H. Rider Haggard, better known for King Solomon's Mines.

  • Melungeon genetic roots

    Fri, 2012-05-25 09:28 -- John Hawks

    The AP is running a story about a recent genetic study probing the ancestry of the Melungeons.

    NASHVILLE, Tenn. (AP) — For years, varied and sometimes wild claims have been made about the origins of a group of dark-skinned Appalachian residents once known derisively as the Melungeons. Some speculated they were descended from Portuguese explorers, or perhaps from Turkish slaves or Gypsies.

    Now a new DNA study in the Journal of Genetic Genealogy attempts to separate truth from oral tradition and wishful thinking. The study found the truth to be somewhat less exotic: Genetic evidence shows that the families historically called Melungeons are the offspring of sub-Saharan African men and white women of northern or central European origin.

    This is the most well-known of a fairly large number of groups of country folk in the southern U.S. with obscure genealogical origins. The story goes on to discuss speculation that their ancestry may derive from indentured servants (of both races) in 1600's Virginia. Whether or not that specific suggestion is correct, shortly after their founding, the American colonies were a remarkably fortunate place for early immigrants. Poor and largely illiterate people who made the crossing had remarkable health, survival rates and fertility by Old World standards. Written history at the level of towns is sometimes surprisingly dense for the early colonies, but was produced by the literate, following their own concerns. Genetics may recapture the dynamics of the lost history of the early colonies, if not the details.

  • Quote: David Thompson on the stars

    Sun, 2012-04-22 12:34 -- John Hawks

    This is maybe as good a definition of science as one could hope for, from the journals of early Canadian fur trader David Thompson:

    Both Canadians and Indians often inquired of me why I observed the sun, and sometimes the moon, in the daytime, and passed whole nights with my instruments looking at the moon and stars. I told them it was to determine the distance and direction from the place I observed to other places. Neither the Canadians or the Indians believed me, for both argued that if what I said was truth, I ought to look to the ground, and over it, and not to the stars.

  • Brittannia rules the waves

    Wed, 2012-03-28 20:03 -- John Hawks

    Ars Technica has an engrossing article by James Grimmelmann about the rise and fall of HavenCo. The firm promised data security and anonymity based on the idea that it was located on the independent nation of Sealand. The problem, of course, was that Sealand isn't really all it's cracked up to be.

    HavenCo's collapse also shows a truly deep irony in its business model. By putting itself outside of other countries' legal systems, it put itself completely at Sealand's mercy. In hindsight, Ryan Lackey explained, "While I could sue HavenCo and/or directors for breach of contract, etc., ... it would presumably lead to a negative resolution of the Sealand sovereignty issue." Sealand is a toy nation with a toy legal system, not a stable business environment. Prince Roy and Prince Regent Michael might be fun to raise a glass with, but they don't inspire the kind of confidence an independent judiciary would. On Sealand, Sean Hastings and Ryan Lackey unwittingly recreated everything that drove them out of Anguilla in the first place.

    It was fun to read about the origin of Sealand in the days of pirate radio and the recurrent attempts to make money off of a very weird situation. Any fan of Cryptonomicon will recognize the plot.

  • Computing past

    Sat, 2012-02-25 19:46 -- John Hawks

    The Guardian has an interview with George Dyson about his new book, Turing's Cathedral: The Origins of the Digital Universe. The book reviews the early history of computing, focusing on John von Neumann's role.

    This passage in the interview is interesting:

    JN Another significant moral of the tale is the importance of open publication. The documentation for the IAS machine was all published, which meant that the machine could be cloned elsewhere (and indeed was by commercial companies such as IBM, as well as other research institutes), whereas the guys who built the ENIAC lodged patents, started a company and in due course became enmeshed in litigation. In our time, the computing industry is increasingly enmeshed in the same kinds of patent wars, so maybe there's a lesson here for us. Is there a correlation between openness and innovation?

    GD Yes, indeed. And what is amazing – and would horrify Abraham Flexner [the founding spirit of the IAS] – is that academic institutions are now leading the way in proprietary restriction on the results of scientific research! Of course there are arguments that this will fund more science, but those arguments do not make sense to me. Again, back to the original agreement made between Oppenheimer and the army at Los Alamos: the weapons would be secret, but the science would be open. And the more we backtrack on that agreement (whether with the military or with industry) the more we lose.

  • A story of methemoglobinemia

    Wed, 2012-02-22 19:57 -- John Hawks

    A story by Susan Donaldson James of a unique genetic disorder and the social stigma of inbreeding in Appalachia: "Fugates of Kentucky: Skin Bluer than Lake Louise".

    By the time reports appeared in the media on the disorder, the Stacy family was upset with insinuations about in-breeding that fed into stereotypes of backwoods Appalachia.

    "There was a pain not seen in lab tests," wrote Trost. "That was the pain of being blue in a world that is mostly shades of white to black."

    The disorder involves an excess of methemoglobin in the blood, related to the examples I've been relating in my Anthropology 105 course the last week or so.
