Cradle and birthday of dog identified

01.09.2009
Previous studies in the field have indicated that East Asia is where the wolf was tamed and became the dog. It was not possible to be more precise than that. But now researchers at the Royal Institute of Technology (KTH) in Stockholm have managed to zero in on man's best friend.

"For the first time in world history it is possible to provide a detailed picture of the dog, with its birthplace, point in time, and how many wolves were tamed," says Peter Savolainen, a biology researcher at KTH.

Together with Swedish colleagues and a Chinese research team, he has made a number of new discoveries about the history of the dog.

These discoveries are presented in an article in the scientific journal Molecular Biology and Evolution, where it is claimed that the dog appeared 16,000 years ago, in Asia, south of the Yangtze River in China.

This is a considerably more specific date and birthplace than had previously been put forward.

"Our earlier findings from 2002 have not been fully accepted, but with our new data there will be greater acceptance. The picture provides much more detail," says Peter Savolainen.

The time for the emergence of the dog conforms well with when the population in this part of the world went from being hunters and gatherers to being farmers, which was 10,000 to 12,000 years ago.

According to Peter Savolainen, the research indicates that the dog has a single geographic origin but descends from a large number of animals. At least several hundred tamed wolves, probably even more.

"The fact that there were so many wolves indicates that this was an important, major part of the culture," says Peter Savolainen.

He adds that the research findings provide several exciting theories. For example, the original dogs, unlike their later descendents in Europe, which were used as herders and guard dogs, probably ended their lives in the stomachs of humans.

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
