Although the discovery itself happened previous year, it was announced in early June at the opening of a woolly mammoth exhibit at the National Museum of Emerging Science and Innovation in Tokyo.
"We want to answer the question of whether these wolves disappeared or turned into modern wolves, how much they are related to modern wolves", Albert Protopopov, head of mammoth fauna studies at the Yakutia academy of sciences, told The Telegraph.
A 40,000-year-old detached wolf head - with its brain intact - has been found in Siberia by scientists.
Both the Swedish and Japanese facilities will continue to study the DNA and internal anatomy of the head, which includes a fully preserved brain.
Alongside the wolf head, scientists also presented a well-preserved cave lion cub named Spartak, which was found around the same time. Because the beast's fur and fangs are still intact, researchers at the University of Sweden are able to analyze tissue from the wolf, something that's usually not preserved in the fossil record. "We've never seen an Ice Age wolf in the flesh before and this is a huge specimen".
It was found by mammoth tusk hunters in Siberia's Verkhoyansk region. It is in near-pristine condition, like the wolf head, and will be compared to modern lions.
The discovery was announced in Tokyo during the grandiose Woolly Mammoth exhibition. Scientists in Yakutia and Tokyo also hope to one day clone a woolly mammoth from tissue discovered in the Siberian permafrost, although such a project is not possible with current techniques.
