Scientists Add Woolly Mammoth DNA to Elephant Cells

The woolly mammoth has been extinct for some 4,000 years ago, but now, researchers are attempting to bring it back to life.

A team at Harvard University has successfully inserted woolly mammoth DNA into the genetic code of an elephant.

The project was led by Harvard genetics professor George Church. He told The Sunday Times, "We prioritized genes associated with cold resistance including hairiness, ear size, subcutaneous fat and, especially, hemoglobin."

Church has spoken about this type of genetic splicing in elephants before.

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

"We would propose to make a hybrid elephant that has the best features of modern elephants and the best features of mammoths."

The Asian elephant is the closest relative to mammoths, although the size of mammoths was similar to that of the larger African elephant.

Church's project isn't without its critics, though.

Some scientists are against using elephants to potentially bring back the woolly mammoths. Professor Alex Greenwood told The Telegraph: "Why bring back another elephantid from extinction when we cannot even keep the ones that are not extinct around? What is the message? We can be as irresponsible with the environment as we want. Then we'll just clone things back?"

The Harvard-led project has not yet been submitted to a journal because the research is ongoing.
