steorra'Dramatic new discoveries illuminate the lost Indus civilization'
An interesting article about the Indus Valley civilization and climate change.
'Then, at the height of Indus urbanization, when the region's cities were growing the largest they had ever been, climate disaster struck. The life-giving monsoons weakened starting in roughly 2200 BCE. Drought crept into some regions, while others were relatively unaffected. And yet the Indus settlements survived for centuries afterward. Writing in Current Anthropology, the researchers say this is why the story of the Indus region "provides a unique opportunity to understand how an ancient society coped with both diverse and varied ecologies as well as change in the fundamental and underlying environmental parameters."'

The milk revolution by Andrew Curry
Aug. 7th, 2013 09:15 amein_myriaThe milk revolution by Andrew Curry (Nature 500, 20–22 (01 August 2013) doi:10.1038/500020a)
"During the most recent ice age, milk was essentially a toxin to adults because — unlike children — they could not produce the lactase enzyme required to break down lactose, the main sugar in milk. But as farming started to replace hunting and gathering in the Middle East around 11,000 years ago, cattle herders learned how to reduce lactose in dairy products to tolerable levels by fermenting milk to make cheese or yogurt. Several thousand years later, a genetic mutation spread through Europe that gave people the ability to produce lactase — and drink milk — throughout their lives. That adaptation opened up a rich new source of nutrition that could have sustained communities when harvests failed."

Restless Genes by David Dobbs
Jan. 4th, 2013 06:04 pmein_myriaArticle Link: Restless Genes by David Dobbs (National Geographic)
“No other mammal moves around like we do,” says Svante Pääbo, a director of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, where he uses genetics to study human origins. “We jump borders. We push into new territory even when we have resources where we are. Other animals don’t do this. Other humans either. Neanderthals were around hundreds of thousands of years, but they never spread around the world. In just 50,000 years we covered everything. There’s a kind of madness to it. Sailing out into the ocean, you have no idea what’s on the other side. And now we go to Mars. We never stop. Why?”
TLDR; The 7R gene and human wanderlust.

ein_myria17,500-Year-Old Ceramic Figures Unearthed in Croatia by John Shanks
"An international team of archaeologists has uncovered the first evidence of ceramic figurative art in late Upper Paleolithic Europe – from about 17,500 years ago, thousands of years before pottery was commonly used."

jeweledeyesI just received this letter from the Archaeological Institute of America and wanted to share it here:
Dear AIA members,
The AIA has learned of two new TV shows that promote treasure hunting to find archaeological objects. National Geographic's "Diggers" airs tonight and Spike TV's "American Diggers" will air next month. Both shows feature metal detectorists and at least one ("American Diggers") emphasizes the commercial value of the found objects. The AIA believes that these shows promote the looting and destruction of archaeological sites.
The AIA has joined several other groups including the SAA, SHA, and RPA in voicing concern about these programs and the negative messages they send about cultural heritage and its recovery. Links to copies of the SAA and SHA letters can be found at the bottom of this letter.
We would like to ask you, our members and archaeology enthusiasts, to send letters and/or e-mails to the companies involved asking them to alter the message of the shows and to provide disclaimers during the airing of the show that makes it clear that what the shows are promoting is unethical and in some instances may even be illegal. We hope that they will engage in a meaningful dialogue with archaeologists about the illicit practices they promote.
Sincerely,
Elizabeth Bartman
President

archaeology_weeklycharameiBritish archaeologists have found an ancient shipyard in Italy that built or maintained ships for the Roman empire.
And this one's more palaeontology than archaeology, but still interesting: A scientist at Yale has found that beetle exoskeletons redshift slightly as they fossilise.

charameiPeople's Daily (English) with pictures
London Metro
I haven't been able to find a decent-length article, probably because they only completed the excavations yesterday (and possibly also because it's China). The People's Daily article has the most pictures. Metro text under the cut:
( Remains of horses and chariots found in 3,000-year-old tomb in China )The main thing that strikes me is that the horses look rather small by modern standards! Maybe it's a perspective thing, or perhaps they were simply pony-sized.

Oxbow books
Aug. 16th, 2011 05:34 pmossamentaFor those not subscribed to me, just to let you know I wrote a long post on books from the recent Oxbow catalogue. Most are rather expensive (being new and often hardbacks), but hopefully your local library will either buy them, or can make interlibrary loans.
Prehistoric society questions
Jun. 21st, 2011 01:20 pmsteorraI have a few questions about prehistoric societies.
I'm under the impression that grain farming and livestock domestication happened around the same time. I'm also under the impression that grain farming usually involves labour animals for ploughing etc. Was there a time and place when grain farming was done without labour animals?
Also, does anyone have any good resources on bronze age technologies? Not just metalworking, but other technologies that were used in bronze age societies.

berangereToday is the last day of Three Weeks For Dreamwidth. Almost all the prompts of the Frequently-Or-Not-So-Frequently-Asked-Questions in Archaeology Project have been answered.
"Almost" means this is not over yet. Here is the second part of the answer to the question fromyvi concerning sciences and archaeology.
Last week I presented the links between archaeology and molecular biology. This post will be an overview of the other sciences used in archaeology. Well, an overview of all the sciences I managed to think about.
( This way please, sciency people... )
These are all the sciences I managed to think about. If someboby wants precisions concerning any field, questions can be asked in the comments, or a prompt can be submitted in the masterpost for the FONSFAQ, that will stay open indefinitely.
The next prompt, about archaeology of buildings, will be answered during next week, even if Three Weeks For Dreamwidth will the over.

berangereThis post belongs to the Frequently-Or-Not-So-Frequently-Asked-Questions in Archaeology project.
I will deal now with molecular biology, and will list the others sciences I can think of in another post (that will probably be dating-methods heavy). First, I'd like to make clear that I had to look for the exact definition of 「Molecular Biology」 in wikipedia. I felt that the limits of this science are quite blurry so I am not sure everything that will be dealt with in this article really relates to molecular biology. Let's say I tried to focus on anything related to genes, cells or proteins. Therefore, it is essentially linked to human remains, that are not found in every archaeological excavation. I suppose the techniques can be applied to animal remains either, according to the problematic of the excavation or the study.
I supposeyvi is quite familiar with molecular biology, hence the question, but I tried to include really basic explanations for the article to be understandable to people with no scientific background. Note that I am not a biologist and that my explanations may not be particularly good.
( Five applications I have frequently encountered )
Those are the only application of molecular biology I can think of. There may be others that I just forgot. I really hope I got the definition of molecular biology correct.
Most of those techniques are quite expensive, therefore not systematically used in a domain like archaeology where the lack of funds is so common it has become a feature we are trained to deal with from the beginning of our formation.
