"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.

New method to rapidly map the 'social networks' of proteins
27.06.2017 | Salk Institute
An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
