WASHINGTONResearch conducted by the National Geographic Genographic Project, a multiyear global initiative that uses DNA to map the history of human migration, is helping unravel the timing and source of human settlement in Central Europe.

New ancient-DNA research led by the National Geographic Society's Genographic Project, the Australian Centre for Ancient DNA (ACAD) and researchers from the University of Mainz in Germany and the State Heritage Museum in Halle (Germany) showed a pattern of genetic replacement taking place across several millennia in a region of central Europe. The genetic data reveal the complex dynamics that went into producing the present-day genetic patterns in Europe and show that the region that is now Germany saw at least four stages of significant migration and settlement, highlighted by marked shifts in the genetic composition of the populations in the region.

One of the great debates in archaeological research for the past century has been the degree to which cultures or people move. When you see a pronounced cultural shift in the archaeological record, for instance, is it because of a new people appearing on the scene, or is it simply the diffusion of a new culture? This new Genographic study shows definitively that, for Germany over a four-millennia-long time span from 5500 B.C. to 1500 B.C., it was people who were on the move, carrying their genes with them.

A paper on the research, "Ancient DNA reveals key stages in the formation of Central European mitochondrial genetic diversity," will be published today, Oct. 10, by the journal Science. The paper is embargoed until 2 p.m. (ET, U.S.) Oct. 10, and can be accessed at http://www.sciencemag.org/lookup/doi/10.1126/science.1241844

"This is the largest and most detailed genetic time series of Europe yet created, allowing us to establish a complete genetic chronology," said joint lead author and Genographic Project scientist Dr. Wolfgang Haak of ACAD. "Focusing on this small but highly important geographic region meant we could generate a gapless record and directly observe genetic changes in 'real time' from 7,500 to 3,500 years ago, from the earliest farmers to the early Bronze Age."

Genographic Project Director Spencer Wells said: "This is perhaps the most important study to date of genetic patterns in Europe during a critical period in the formation of modern Europe. Painstakingly collected data from well-dated archaeological remains spanning a period from the dawn of farming during the Neolithic period to the Bronze Age reveal successive waves of migration and population replacement genetic 'revolutions' that combined to create the genetic patterns we see today."

Representatives of the Genographic Project, which uses advanced, multi-locus DNA analyses to help answer fundamental questions about human origins, looked at the mitochondrial DNA control region sequences from remains of 364 people from different prehistoric time periods and cultures of Central Europe and performed a chronological genetic study that spanned more than 4,000 years.

The remains from each time period were associated with known archaeological cultures of that time. Likewise, each period's remains were interpreted as indicative of that region's genetic diversity at that time, thus constituting a distinct population from other time periods. Each population showed marked differences from the others from the same region.

Ancient DNA reveals multiple stages of settlement in Europe

Oct. 10, 2013 Ancient DNA recovered from a time series of skeletons in Germany spanning 4,000 years of prehistory has been used to reconstruct the first detailed genetic history of modern-day Europeans.

The study, published today in Science, reveals dramatic population changes with waves of prehistoric migration, not only from the accepted path via the Near East, but also from Western and Eastern Europe.

The research was a collaboration between the Australian Centre for Ancient DNA (ACAD), at the University of Adelaide, researchers from the University of Mainz, the State Heritage Museum in Halle (Germany), and National Geographic Society's Genographic Project. The teams used mitochondrial DNA (maternally inherited DNA) extracted from bone and teeth samples from 364 prehistoric human skeletons ten times more than previous ancient DNA studies.

"This is the largest and most detailed genetic time series of Europe yet created, allowing us to establish a complete genetic chronology," says joint-lead author Dr Wolfgang Haak of ACAD. "Focussing on this small but highly important geographic region meant we could generate a gapless record, and directly observe genetic changes in 'real-time' from 7,500 to 3,500 years ago, from the earliest farmers to the early Bronze Age."

"Our study shows that a simple mix of indigenous hunter-gatherers and the incoming Near Eastern farmers cannot explain the modern-day diversity alone," says joint-lead author Guido Brandt, PhD candidate at the University of Mainz. "The genetic results are much more complex than that. Instead, we found that two particular cultures at the brink of the Bronze Age 4,200 years ago had a marked role in the formation of Central Europe's genetic makeup."

Professor Kurt Alt (University of Mainz) says: "What is intriguing is that the genetic signals can be directly compared with the changes in material culture seen in the archaeological record. It is fascinating to see genetic changes when certain cultures expanded vastly, clearly revealing interactions across very large distances." These included migrations from both Western and Eastern Europe towards the end of the Stone Age, through expanding cultures such as the Bell Beaker and the Corded Ware (named after their pots).

"This transect through time has produced a wealth of information about the genetic history of modern Europeans," says ACAD Director Professor Alan Cooper. "There was a period of stasis after farming became established and suitable areas were settled, and then sudden turnovers during less stable times or when economic factors changed, such as the increasing importance of metal ores and secondary farming products. While the genetic signal of the first farming populations becomes increasingly diluted over time, we see the original hunter-gatherers make a surprising comeback."

Dr Haak says: "None of the dynamic changes we observed could have been inferred from modern-day genetic data alone, highlighting the potential power of combining ancient DNA studies with archaeology to reconstruct human evolutionary history." The international team has been working closely on the genetic prehistory of Europeans for the past 7-8 years and is currently applying powerful new technologies to generate genomic data from the specimens.

Ancient DNA unravels Europe's genetic diversity

DUBLIN--(BUSINESS WIRE)--

Research and Markets (http://www.researchandmarkets.com/research/ssv4lg/dna_and_rna) has announced the addition of the "DNA and RNA Isolation Techniques: Market Developments, Growth Areas and Opportunities" report to their offering.

Extraction methods used to isolate DNA and RNA are fundamental to most studies carried out in the molecular biology field. These molecules are isolated prior to downstream processing for a wide range of applications, from fundamental research to routine diagnostic and therapeutic decision-making. In the past, methods used to extract nucleic acids were often complex, time-consuming, labour-intensive and limited in throughput. Today, many specialized methods are available to scientists, from conventional solution-based approaches, to solid-phase systems that are often used in commercial kits.

Developments in this field are allowing scientists to evaluate new techniques in their own areas of application. Some of these are also amenable to automation, an increasing requirement in many of today's laboratories. Biopharm Reports has carried out a global market study of DNA and RNA isolation techniques involving the participation of 227 experienced end-users in this field. Participants mean 'years of experience' in the use of DNA and RNA isolation techniques was 14.4 years and the findings of this study provide a wealth of information relevant to suppliers in this field. In particular, these findings relate to end-users current and three-year plans, as well as their anticipated purchasing decisions from particular suppliers over the next three years (2013 - 2016).

This study was carried out to provide business information to developers, manufacturers and suppliers in the DNA/RNA extraction/isolation field. Its findings identify marketing and sales opportunities, end-user purchasing decisions, market growth and shrinkage and related information. It was conducted through specialist groups of experienced end-users in the DNA/RNA extraction/isolation field and its findings are therefore based on 'real world' market data.

DNA RNA 2013 presented more than 40 specialised technical/market questions relating to the isolation or extraction of DNA and RNA, and was designed for scientists or managers who use these techniques in their everyday activities, but excluded commercial developers and vendors.

This market analysis was carried out to provide business information to developers, manufacturers and suppliers in the DNA/RNA extraction/isolation field.

Its findings include:

- Marketing and sales opportunities

- End-user purchasing decisions

DNA from ancient skeletons has revealed how a complex patchwork of prehistoric migrations fashioned the modern European gene pool.

The study appears to refute the picture of Europeans as a simple mixture of indigenous hunters and Near Eastern farmers who arrived 7,000 years ago.

The findings by an international team have been published in Science journal.

DNA was analysed from 364 skeletons unearthed in Germany - an important crossroads for prehistoric cultures.

"This is the largest and most detailed genetic time series of Europe yet created, allowing us to establish a complete genetic chronology," said co-author Dr Wolfgang Haak of the Australian Centre for DNA (ACAD) in Adelaide.

"Focusing on this small but highly important geographic region meant we could generate a gapless record, and directly observe genetic changes in 'real-time' from 7,500 to 3,500 years ago, from the earliest farmers to the early Bronze Age."

Dr Haak and his colleagues analysed DNA extracted from the teeth and bones of well-preserved remains from the Mittelelbe-Saale region of Germany. They focused on mitochondrial DNA (mtDNA) - the genetic information in the cell's "batteries".

When you look at today's populations, what you are seeing is a hazy palimpsest of what actually went on to create present-day patterns

MtDNA is passed down from a mother to her children, allowing geneticists to probe the maternal histories of populations. Geneticists recognise a variety of mitochondrial DNA "clans", or lineages, in human populations. And each of these lineages has its own distinct history.
