2015年5月22日 · A team of scientists from the Swedish Museum of Natural History and elsewhere sequenced and analyzed the draft genome of a 35,000-year-old wolf from the Taimyr Peninsula in northern Siberia, and found that this individual represents the most recent common ancestor of modern wolves and dogs.

Here, we present a draft genome sequence from a 35,000-year-old wolf from the Taimyr Peninsula in northern Siberia. We find that this individual belonged to a population that diverged from the common ancestor of present-day wolves and dogs very close in time to the appearance of the domestic dog lineage.

2015年5月23日 · The discovery of a 35,000-year-old wolf rib bone in the Taimyr peninsula in northern Siberia was the key to this story. The DNA from that bone suggests that it diverged from a common ancestor of present-day wolves and dogs near the beginning of the domestic dog lineage. Their technique uses genetic drift of ‘regular’ DNA and mitochondrial DNA.

The Evenki people originally used this name for the Taimyr River, known for its abundance of fish. In the 19th century, thanks to the geographer and explorer Alexander von Middendorff (1815–1894), the name came to refer to the entire peninsula .

We found these specimens cluster with the two previously sequenced Pleistocene wolves, which are genetically more similar to Eurasian wolves. Our results show that, though the four spec-imens represent extinct wolf lineages, they do not form a monophyletic group.

2015年5月22日 · CAMBRIDGE, MASSACHUSETTS—DNA from an ancient Taimyr wolf bone from Siberia has been compared to DNA from modern dogs by Pontus Skoglund of Harvard …

Taimyr wolf (plural Taimyr wolves) An ancient wolf that inhabited the Taimyr Peninsula of northern Siberia.

In the present study, we assess how genotype imputation of ancient dog and wolf genomes, utilising a large reference panel, can improve the resolution afforded by ancient genomic datasets.

Dogs' special relationship to humans may go back 27,000 to 40,000 years, according to genomic analysis of an ancient Taimyr wolf bone reported in the Cell Press journal Current Biology on May 21.

2015年5月21日 · As they reported online today in Current Biology, the researchers sequenced mitochondrial and genomic DNA from the 35,000-year-old remains of an ancient wolf, known as Taimyr 1 that was discovered in northern Siberia's Taimyr Peninsula.
