Scientists Close In On Their Goal To Resurrect The Woolly Mammoth


The woolly mammoth hasn't roamed the planet for thousands of years, but that could soon change.

A team of scientists has gotten one large step closer to resurrecting the shaggy species.

Researchers working on reversing the animal's extinction have almost fully sequenced a genome by using DNA from two Siberian specimens.

One of the animals lived about 45 thousand years ago, while the other hails from much more recent times, being around 43-hundred years old.

Between information gathered from both, the team has constructed their clearest picture to date of what made the woolly mammoth tick.

Their advancement also offers clues into what may have contributed to their demise.

Popular theories for why the animals ceased to exist include being overhunted by humans and climate change.

Though the scientists are closer than ever to realizing their de-extinction goal, the question looms as to whether they should do it or not.

One of the researchers acknowledges that there are a number of ethical matters involved.

Those include the potential that the effort could compromise conservation projects devoted to already living, yet endangered, animals.

WASHINGTON, DC - OCTOBER 15: Paleo Biology curator Matthew Carrano near the foot of a Wooly Mammoth skeleton being deconstructed at the Smithsonian Museum of Natural History in Washington, DC on October 20, 2014. It's all part of an overall renovation of the museum's Fossil Halls. All of the dinosaur skeletons are being disassembled, refurbished and repositioned and will reappear at the Smithsonian museum in 2019. This dinosaur exhibit has been on display since the late 70's / early 80's. The Mammoth skeleton is a combination of bones of several Mammoths found in Alaska; some dating back to 1930's. Any parts that were missing or damaged were filled in with a wax/wood substance. The crew from Research Casting International will ship the skeleton to Canada where it will undergo refurbishing, repositioning and then returned to the museum for the new exhibit.

Lyuba, her name taken from the word for love in Russian, was discovered frozen in clay and mud in Russia's Yamal Peninsula of Siberia in 2007 and is estimated to have died around 42,000 years ago at one month old. She is 85cm tall and 130 cm long, and is on loan from Russia's Shemanovsky Museum to feature in the exhibition "Mammoths: Ice Age Giants", which runs from March 23 to September 7.

Russian researchers say they have discovered a perfectly preserved woolly mammoth carcass with liquid blood on a remote Arctic island, fueling hopes of cloning the Ice Age animal. The frozen remains of a female mammoth were so well preserved that blood came running out after it was recovered from ice. (AP Photo/Rossiya Television, AP Video) TV OUT
