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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
