Science's breakthrough of the year: Uncovering 'Ardi'

The research that brought to light the fossils of Ardipithecus ramidus, a hominid species that lived 4.4 million years ago in what is now Ethiopia, has topped Science's list of this year's most significant scientific breakthroughs. The monumental find predates "Lucy,"—previously the most ancient partial skeleton of a hominid on record—by more than one million years, and it inches researchers ever-closer to the last common ancestor shared by humans and chimpanzees.

Science and its publisher, AAAS, the nonprofit science society, recognize the Ardipithecus ramidus fossils, including the partial skeleton named "Ardi," as 2009's Breakthrough of the Year. They also identify nine other important scientific accomplishments from this past year in a top ten list, appearing in a special news feature in the journal's 18 December 2009 issue.

Human Ancestors Were Homemakers

In a stone-age version of "Iron Chef," early humans were dividing their living spaces into kitchens and work areas much earlier than previously thought, a new study found.

So rather than cooking and eating in the same area where they snoozed, early humans demarcated such living quarters.

Archaeologists discovered evidence of this coordinated living at a hominid site at Gesher Benot Ya‘aqov, Israel from about 800,000 years ago. Scientists aren't sure exactly who lived there, but it predates the appearance of modern humans, so it was likely a human ancestor such as Homo erectus.

2010 preview: Arise, Neanderthal brother

Do we have a little Neanderthal in us? That's not a reference to your behaviour at the end-of-year office party, but to the genes of our extinct cousins. With the imminent publication of the genome sequence of Homo neanderthalis, that question may finally be answered.

So far no one has uncovered evidence of any cross-species romps - at least none that left a trace in our DNA. The 3-billion-nucleotide Neanderthal genome is our best chance yet of finding out.

Stone Age Pantry: Archaeologist Unearths Earliest Evidence of Modern Humans Using Wild Grains and Tubers for Food

The consumption of wild cereals among prehistoric hunters and gatherers appears to be far more ancient than previously thought, according to a University of Calgary archaeologist who has found the oldest example of extensive reliance on cereal and root staples in the diet of early Homo sapiens more than 100,000 years ago.

Julio Mercader, holder of the Canada Research Chair in Tropical Archaeology in the U of C's Department of Archaeology, recovered dozens of stone tools from a deep cave in Mozambique showing that wild sorghum, the ancestor of the chief cereal consumed today in sub-Saharan Africa for flours, breads, porridges and alcoholic beverages, was in Homo sapiens' pantry along with the African wine palm, the false banana, pigeon peas, wild oranges and the African "potato."

4,000-year-old-year-old flowers found at Bronze Age dig

For the first time ever there is proof that pre-historic people placed bunches of flowers in the grave when they buried their dead, experts have said.

Archaeologists have discovered a bunch of meadowsweet blossoms in a Bronze Age grave at Forteviot, south of Perth.

The find is reported in the journal "British Archaeology", out this week.

Ancient site reveals signs of mass cannibalism

Archaeologists have found evidence of mass cannibalism at a 7,000-year-old human burial site in south-west Germany, the journal Antiquity reports.

The authors say their findings provide rare evidence of cannibalism in Europe's early Neolithic period.

Up to 500 human remains unearthed near the village of Herxheim may have been cannibalised.

French immigrants founded first British farms

THE British may owe the French more than they care to admit. Archaeological finds from Britain show that farming was introduced 6000 years ago by immigrants from France, and that the ancient Brits might have continued as hunter-gatherers had it not been for innovations introduced by the Gallic newcomers.

Mark Collard from Simon Fraser University in British Columbia, Canada, and his colleagues studied carbon-14 dates for ancient bones, wood and cereal grains from locations across Great Britain. From this they were able to assess how population density changed with time, indicating that around 6000 years ago the population quadrupled in just 400 years (Journal of Archaeological Science, DOI: 10.1016/j.jas.2009.11.016). This coincides with the emergence of farming in Britain.

Oslo growing older

Archeologists now say Oslo's history will have to be re-written. They have made new escavations which show that people have lived on the Ekeberg heights east of the capital for 10,000 years.

The artifacts found include flint chips and other evidence of tool production, which show that people have lived here more than 2000 years longer than experts previously believed.

The new find includes a settlement, which in those days was located at the waters edge, but now is found high up in the hillside. The land has risen after the ice cap which covered much of the area melted.

Debate Over Evidence of Mass Cannibalism

At a settlement in what is now southern Germany, the menu turned gruesome 7,000 years ago. Over a period of perhaps a few decades, hundreds of people were butchered and eaten before parts of their bodies were thrown into oval pits, a new study suggests.

Cannibalism at the village, now called Herxheim, may have occurred during ceremonies in which people from near and far brought slaves, war prisoners or other dependents for ritual sacrifice, propose anthropologist Bruno Boulestin of the University of Bordeaux 1 in France and his colleagues. A social and political crisis in central Europe at that time triggered various forms of violence, the researchers suspect.

“Human sacrifice at Herxheim is a hypothesis that’s difficult to prove right now, but we have evidence that several hundred people were eaten over a brief period,” Boulestin says. Skeletal markings indicate that human bodies were butchered in the same way as animals.
