South Koreans Kick Off Efforts to Clone Extinct Siberian Cave Lions

(Read the article on one page)

Samples taken from cubs frozen in permafrost for at least 12,000 years.

Two infant prehistoric big cats - dating from Pleistocene times - were found in a 'sensational' discovery last year, as disclosed by The Siberian Times . The cubs were dug from their icy grave 'complete with all their body parts: fur, ears, soft tissue and even whiskers', said Dr. Albert Protopopov, head of the mammoth fauna studies department of the Yakutian Academy of Sciences.

Now cloning expert Hwang Woo-suk, a South Korean scientist who is already pioneering research work to bring the extinct woolly mammoth back to life, is in Yakutsk to obtain samples of one of the cave lion cubs. These laboratory pictures show skin and muscle tissue being extracted from the ancient creature “Dina's” remains.

Dr. Protopopov said: 'Together with the Mammoth Museum, we took samples for cell research.' The museum's experts will study these for the presence of living cells suitable for cloning.

Hwang came to Yakutsk - capital of the Sakha Republic - specifically for this purpose. But there was dispute between the Siberian and Korean scientists over the size of the sample.

The Korean professor wanted a large section, such as part of the skull or a leg but this was opposed by the local experts who are anyway withholding one of the cubs from any research - the better preserved of the pair, called Uyan - confident that more advanced techniques in future years will ensure more is gleaned from it than if research is done now.

Dr. Protopopov said: 'We intend to keep it for the future. The methods of research are constantly being improved, about once a decade there is a mini-revolution in this area. So we will do everything possible to keep this carcass frozen for as long as possible.'

He revealed: 'The dispute arose from the fact that the researchers, as always, want to be completely sure and take more tissue, and I can understand them. But the lion is not fully preserved and there are not so many tissues. We have planned other studies, so it is important to preserve the original morphology of the remains. Such disputes are normal in all studies, and in the end we came to a compromise.'

Director of the Mammoth Museum Semyon Grigoriev defended the decision to limit the sample available to the cloning guru.

'The Koreans are skeptical and unhappy with the samples,' he said. 'They expected to take more, as they did with the mammoth previously. But it will not work with these little kittens.

'You have to understand, the lion cub is very small, so it was not possible to take as much as we would like. In addition, the material is highly degraded, it is partially mummified, but the part that was in the ice, preserved very well. We managed to take some samples of skin along with the muscle tissue, and we hope that we will find what we want in these samples.'

An autopsy of the animal is due to be held later this year.

The cave lions were found some 650 miles northeast of Yakutsk, in Yakutia, also known as the Sakha Republic, a Siberian region almost as large as India. A sudden summer rise - then fall - in the level of the Uyandina River led to cracks appearing and local worker Yakov Androsov spotted an ice lens with the lion cubs inside.

Dr. Protopopov said last year when he showed the cubs to the media: 'Comparing with modern lion cubs, we think that these two were very small, maybe a week or two old. The eyes were not quite open, they have baby teeth and not all had appeared.'

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
