Tracing humanity's African ancestry may mean rewriting 'out of Africa' dates

 New research by a University of Alberta archeologist may lead to a rethinking of how, when and from where our ancestors left Africa.

U of A researcher and anthropology chair Pamela Willoughby's explorations in the Iringa region of southern Tanzania yielded fossils and other evidence that records the beginnings of our own species, Homo sapiens. Her research, recently published in the journal Quaternary International, may be key to answering questions about early human occupation and the migration out of Africa about 60,000 to 50,000 years ago, which led to modern humans colonizing the globe.

From two sites, Mlambalasi and nearby Magubike, she and members of her team, the Iringa Region Archaeological Project, uncovered artifacts that outline continuous human occupation between modern times and at least 200,000 years ago, including during a late Ice Age period when a near extinction-level event, or "genetic bottleneck," likely occurred.

Australia. In search of the world's oldest cave etching

I'M DRIVING across South Australia's featureless but iconic Nullarbor Plain when suddenly the red earth falls away into a black abyss. "Dramatic really is the word for it," says Keryn Walshe.

Fifty metres wide and 25 metres deep, the sinkhole is a gateway to the mysterious Koonalda caves.Walshe, an archaeologist from the South Australian Museum, is leading a group of researchers and members of the Mirning people, the traditional Aboriginal owners of the land, into the caves. It has taken us 6 hours to drive here, after flying in from Adelaide, the nearest city, 900 kilometres away.

We have come to see strange wall markings that may have been a tactile code left by flint miners during the last ice age. The mine might be among the oldest in the world, as may the markings. The flint has clearly been cut away in numerous places and worked into tools, and ash deposits from fires show people have been coming here for tens of thousands of years. [...] New Scientist

Hominins already inhabited the Three Gorges region of South China in Pleistocene

Systematic archaeological survey and excavations in the Three Gorges region, South China over the past two decades has led to the discovery of a number of important hominin fossils and Paleolithic stone artifact assemblages.

Dr. PEI Shuwen, Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences, and his collaborators reviewed the results of recent paleoanthropological, particularly Paleolithic archaeological, research from this region, and concluded that Middle to Late Pleistocene hominins already Inhabited the Three Gorges Region of South China and the Paleolithic technology is essentially an Oldowan-like industry (i.e., Mode 1 core and flake technologies). This study was published online in the journal of Quaternary International (2012). [..]

Bulgaria. Archaeologists Uncover Europe's First Civilization

Ancient mound in Bulgaria yields vestiges of one of the first urban settlements in Europe.

A team of archaeologists have unearthed additional evidence of what may have been Europe's first civilization at a site located near the town of Pazardzhik in southern Bulgaria. Known as Yunatsite, it is a Tell (mound containing archaeological remains) about 110 meters in diameter and 12 meters high, rising above fields next to a small Bulgarian village by the same name. The Tell contains remains of an urbanized settlement dated at its earliest to the early fifth millenium BC.

Directed by Yavor Boyadzhiev of the National Institute of Archaeology and Museums, Bulgarian Academy of Sciences, excavators have unearthed artifacts such as weapons, Spondylus jewels, decorated fineware pottery, shards marked by characters/pictograms, and evidence of structures dated to 4900 BC, including fortifications and a recently discovered wooden platform that was likely the floor of a building that had been destroyed by fire.

Un equipo de arqueólogos ha desenterrado evidencia adicional de lo que pudo haber sido la primera civilización europea en un lugar ubicado cerca de la ciudad de Pazardzhik, en el sur de Bulgaria.

Conocido como Yunatsite, se trata de un Tell (montículo que contiene restos arqueológicos) de unos 110 metros de diámetro y 12 metros de alto, elevándose por encima de los campos próximos al pequeño pueblo búlgaro del mismo nombre. El Tell contiene restos de un asentamiento urbanizado datado en los primeros años del V milenio a.C...

Actualización 11-11-14. “Yunatsite” settlement mound and the oldest European civilization
Evidence has been piling up in favour of a very bold theory - that it is the Balkan Peninsula, rather than ancient Mesopotamia that is the cradle of our civilization. The evidence of a little known culture preceding Egyptian and even Sumerian culture has been attracting the attention of researchers, turning everything we know about antiquity upside down. Remains of this ancient society have gradually been emerging from the ashes of human history taking us some 6-7 millennia back in time when a highly-advanced unknown civilization flourished in our lands, a period which preceded Sumer and Akkad by at least one millennium...

Researchers find first evidence of Ice Age wolves in Nevada

 A research team recently unearthed fossil remains from an extinct wolf species in a wash northwest of Las Vegas, revealing the first evidence that the Ice Age mammal once lived in Nevada.

The metapodial, or foot bone, was uncovered late last year by UNLV geologist Josh Bonde during a survey of the Upper Las Vegas Wash. They have now confirmed that the bone comes from a dire wolf.

The discovery site is near the proposed Tule Springs Fossil Beds National Monument, a fossil-rich area known for its diversity and abundance of Ice Age animal remains. Scientists estimate the fossil to be 10,000 to 15,000 years old during the Late Pleistocene period. [...]  ScienceDaily

Archaeology Magazine's Top 10 Discoveries of 2012

... Here you’ll see discoveries that range from a work of Europe’s earliest wall art to the revelation that Neanderthals, our closest relatives, selectively picked and ate medicinal plants, and from the unexpected discovery of a 20-foot Egyptian ceremonial boat to the excavation of stunning masks that decorate a Maya temple and tell us of a civilization’s relation to the cosmos.

Then there are the discoveries that just made us wonder. What drove someone to wrap their valuables in a cloth and hide them almost 2,000 years ago? And why were people in Bronze Age Scotland gathering bones and burying them in bogs?

The finds span the last 50,000 years and cover territories from the cradle of civilization to what is today one of the world’s most populous cities. These are a few of the discoveries that speak to us of both our record of ingenuity and our humanity. The enduring question is always: Were the people behind the evidence anything like us? [...]
