Elephantid Genomes Reveal the Molecular Bases of Woolly Mammoth Adaptations to the ArcticAuthors:Lynch et alAbstract:Woolly mammoths and living elephants are characterized by major phenotypic differences that have allowed them to live in very different environments. Show More Summary
The first comprehensive analysis of the woolly mammoth genome reveals extensive genetic changes that allowed mammoths to adapt Arctic life, including skin and hair development, insulin signaling, fat biology, and even traits such as small ears and short tails. A mammoth gene for temperature sensation was resurrected in the lab as a functional test.
No one has brought a woolly mammoth back from extinction, but a team of scientists has brought back a woolly mammoth gene, discovering that it and others unique to the long-vanished elephant-like beasts probably helped the animals withstand the harsh cold of the Arctic tundra.
With the science nearly upon us, a new book highlights the ethical and logistical issues of bringing back proxies of extinct animals such as the woolly mammoth
Flying Puffin, Wikimedia Commons // CC BY-SA 2.0 Around 4000 years ago, the last woolly mammoths disappeared from Earth. Those final survivors lived and died on Wrangel Island, off the coast of northeast Russia. Their mainland Siberian relatives had died out some 6000 years before that. Show More Summary
In this curious 1962 film clip from British Pathé, a man gets a custom beard and mustache wig from a London wigmaker. The film’s narrator makes much light of the retro fashion for beards in 1960s England. Given the woolly mammoths who roam the highs streets of America’s hippest cities, surely a remake is in […]

The most complete genetic information assembled on woolly mammoths is providing insight into their demise, revealing that they suffered two population crashes before a final, severely inbred group succumbed on an Arctic Ocean island.Read full article >>
Scientists may be one step closer to bringing the woolly mammoth back to life. In a new study, an international team of researchers has sequenced the genomes of two Siberian woolly mammoths -- revealing the most complete genetic blueprint...Show More Summary
Scientists Sequence the Mammoth Genome, not Once but Twice A new study of the genomes of two Woolly Mammoths has been published in the scientific journal “Current Biology”. An international team of researchers have been able to sequence the complete genome of two of these iconic, ancient elephants. The researchers are not involved in experiments […]

The last of the woolly mammoths in Siberia died out about 10,000 years ago, but a smaller number living on Wrangel Island, off the coast of what is now Russia, managed to stick around for another 6,000 years. Researchers set out to investigate the two groups and the...
Who needs a woolly mammoth? I ask this question because scientists with apparently nothing better to do are attempting to bring back the beast, which went extinct some 4,000 years ago, and thank God for that. The woolly creature’s DNA has been sequenced, and things appear ripe for what is called “mammoth de-extinction.” The Post’s […]
Genetic factors may have been responsible for their disappearance
In what may be a first for a long-extinct non-human animal -- and certainly for an extinct creature of such stature -- scientists have assembled the complete genome of the woolly mammoth, gaining insight into why the last surviving population of the great beasts, marooned on an Arctic island off...
With two sequenced woolly mammoth genomes, scientists hope to learn what killed it - and whether it could be brought back
As scientists move closer to decoding the genome of woolly mammoths, some scientists are raising ethical concerns about the possibility of cloning extinct animals. CBS News' Kera Rennert spoke with Dr. Ross MacPhee, the curator of the Department of Mammalogy at the American Museum of Natural History, about the controversy.
An international team of researchers has sequenced the nearly complete genome of two Siberian woolly mammoths -- revealing the most complete picture to date -- including new information about the species' evolutionary history and the conditions that led to its mass extinction at the end of the Ice Age.
