Bringing Extinct Animals Back To Life
2013-03-15 04:45:55

Lee Rannals for redOrbit.com - Your Universe Online The idea of bringing woolly mammoths and saber tooth cats back from the dead has been a popular one, and this concept of "de-extinction" is the focus National Geographic's cover for its April issue. Author Carl Zimmer wrote in April's National Geographic cover story about what scientists have done, and are doing to work on bringing some extinct species back from the dead. Species discussed in the feature focus on those that went...

SEATTLE, July 10, 2012 /PRNewswire/ -- Dodo Destiny: An American Eye on Mauritius by Tom Parker examines the sad tale of the dodo and the unique history of Mauritius and neighboring islands in the Indian Ocean. (Photo: http://photos.prnewswire.com/prnh/20120710/SF36905) The flightless dodo is perhaps the most famous symbol of the dangers of global extinction with a universally recognized image. Despite this fame, little is known about the true nature of this vanished bird. The threat of...

Although humans and woolly mammoths co-existed for millennia, the shaggy giants disappeared from the globe between 4,000 and 10,000 years ago, and scientists couldn't explain until recently exactly how the Flinstonian behemoths went extinct. In a paper published June 12 in the journal Nature Communications, UCLA researchers and colleagues reveal that not long after the last ice age, the last woolly mammoths succumbed to a lethal combination of climate warming, encroaching humans and...

Canadian Family Finds Ancient Bison Skeleton In Their Basement

Brett Smith for Redorbit.com Canadian Craig Duncan was digging a trench in the basement of his new house in the Yukon Territory capital of Whitehorse when he stumbled over something unusual. “We were down about three feet, sifting through some of the stones down there to lay the electrical lines when I kicked what looked like a piece of bone,” Duncan said in an interview with the Canadian Press. “First, I thought it could be a dinosaur or something, but when we saw...

The woolly mammoth died out suddenly and without a loss of genetic variation, all but ruling out climate change and inbreeding as possible causes of their extinction, according to a study published Tuesday in the Proceedings of the Royal Society B. According to a March 30 article by Marlowe Hood of the AFP, "The culprit might have been disease, humans or a catastrophic weather event, but was almost certainly not climate change." Furthermore, the scientists, including Anders Angerbjorn of...

Scientists found that Tasmanian "tigers" may have gone extinct due to inbreeding and are considering resurrecting the Australian marsupials 70 years after they ceased to exist. "Our goal is to learn how to prevent endangered species from going extinct," said Webb Miller of Pennsylvania State University, who helped lead the international study. The researchers used the same method used to study the DNA from extinct woolly mammoths' hair to get a good comparison of the gene sequences from...

The sabertooth cat (Smilodon fatalis), one of the most iconic extinct mammal species, was likely to be a social animal, living and hunting like lions today, according to new scientific research. The species is famous for its extremely long canine teeth, which reached up to seven inches in length and extended below the lower jaw. Instead of relying on the bones and teeth of the sabertooths to make their findings, scientists from UCLA and the Zoological Society of London concluded that the...

U.S. researchers said the bones of wolves can provide scientists with a better picture of environmental change than tree rings can. "Since the widespread combustion of fossil fuels, we have put a human fingerprint on atmospheric carbon dioxide," Joseph Bump, a forest science researcher at Michigan Technological University, said in a release. "That fingerprint shows up in trees, and it shows up in animals that eat trees, but it shows up with the least variation in the top predators." Bump...

DNA from an extinct creature has been resurrected in a live animal for the first time. The genetic material, extracted from the extinct Tasmanian tiger, proved functional in mice. "As more and more species of animals become extinct, we are continuing to lose critical knowledge of gene function and their potential," said researcher Andrew Pask, a molecular biologist at the University of Melbourne in Australia. Reviving genes from extinct animals can't bring them back to life, but it...

By ROD McGUIRK CANBERRA, Australia - Scientists are planning to move Tasmanian devils - the Australian marsupial made famous as a snarling, whirlwind character in Warner Bros. cartoons - to an island sanctuary to avert the animals' threatened extinction from a mysterious cancer. But some scientists fear that in their haste to save the species, authorities could wreak further environmental damage and risk the survival of other endangered animals by introducing the devils into a habitat...
