    Acting as super-predators, humans are forcing changes to body size and reproductive abilities in some species 300 percent faster than would occur naturally, a new study finds. Hunting and fishing by individual sportsmen as well as large-scale commercial fishing are also outpacing other human influences, such as pollution, in effects on the animal kingdom.

    Animals go extinct, places too. And stories change. Boaz, a small village in Richland County, Wis., has only 156 people these days. There are a half-dozen streets, a couple of taverns, a small park with a baseball diamond and, on the outskirts, a historic marker describing the village's lone claim to fame: "the Boaz Mastodon." The story on the marker is the one that's been told to schoolchildren for almost a century as they stare up at the mastodon skeleton, enshrined in the University of Wisconsin-Madison Geology Museum. It is a story that, until now, has endured largely unchanged: One...
  • Woolly Mammoth Clones Closer Than Ever, Thanks to Genome Sequencing

    Live Science ^ | 07/03/2015 | by Tia Ghose, Senior Writer
    Scientists are one step closer to bringing a woolly mammoth back to life. A new analysis of the woolly mammoth genome has revealed several adaptations that allowed the furry beasts to thrive in the subzero temperatures of the last ice age, including a metabolism that allowed them to pack on insulating fat, smaller ears that lost less heat and a reduced sensitivity to cold. The findings could enable researchers to "resurrect" the ice-age icon — or at least a hybridized Asian elephant with a few of the physical traits of its woolly-haired cousin, said study co-author Vincent Lynch, an evolutionary...

    It will definitely be possible within the foreseeable future to bring back the long-extinct woolly mammoth, a top geneticist has said. However, in his regretful opinion such a resurrection should not be carried out. The assertion comes in the wake of a new study of mammoth genetics as compared to their cousins the Asian and African elephants, which live in warm habitats very different from the icy northern realms of the woolly giant. The new study offers boffins many revelations as to the differences which let the elephants and mammoths survive in such different conditions. “This is by far the...

    Alaska's first full mammoth skeleton may be lurking under Arctic lake. When an aquatic ecologist was surveying shallow lakes in Northwest Alaska three years ago, she and the pilot who traveled with her came upon an unusual sight in the treeless Arctic region: a pair of terns that kept flying around and perching on what appeared to be a log sticking out of a muddy area. The protruding object, it turns out, was no log. It was the large and well-preserved leg bone of a woolly mammoth. Right by it was another bone, perfectly articulated, that was clearly from the...

    Paleontologists are calling a recent find in the Russian region of Yakutia a “sensation.” Last September, Aleksandr Banderov and his hunting party were traveling near the Semyulyakh River when they uncovered the preserved carcass of an adolescent wholly rhinoceros, a species that roamed the frozen landscapes of Europe and northern Asia during the last Ice Age. The hunters initially thought it was a reindeer frozen in the ice, but quickly realized it was something much older. “We were sailing past a ravine and noticed hair hanging on the top of it,’ Alexander told The Siberian Times. “At first we thought...

    A group of Russian and South Korean researchers has begun their attempt to clone a woolly mammoth, starting by extracting DNA from a spectacularly well-preserved specimen discovered in the Siberian permafrot in 2013. The project is led by Hwang Woo-Suk, a Korean cloning scientist who was the focus of a scandal in 2006 involving fraudulent research on human stem cells. Hwang has had success with animals, however, reportedly creating the world's first cloned dog and several cloned coyotes.

    Recent scientific findings date their arrival earlier than ever thought, sparking hot debate among archaeologists For much of its length, the slow-moving Aucilla River in northern Florida flows underground, tunneling through bedrock limestone. But here and there it surfaces, and preserved in those inky ponds lie secrets of the first Americans.For years adventurous divers had hunted fossils and artifacts in the sinkholes of the Aucilla about an hour east of Tallahassee. They found stone arrowheads and the bones of extinct mammals such as mammoth, mastodon and the American ice age horse.Then, in the 1980s, archaeologists from the Florida Museum of...

    They're probably about half as old as scientists once thought they were. But a pair of butchered bones found in a cave near the Alaska-Yukon border are "definite" evidence of human presence in North America just after the end of the last Ice Age, perhaps as much as 14,000 years ago, according to a new study. The bones were originally discovered in the late 1970s by Canadian archaeologist Dr. Jacques Cinq-Mars at a site known as Bluefish Caves, high in northwestern Yukon Territory. In one of the caves, dubbed Cave 2, archaeologists found more than 18,000 fragments of bones from...

    Indian DNA links to 6 'founding mothers' By MALCOLM RITTER, AP Science Writer NEW YORK - Nearly all of today's Native Americans in North, Central and South America can trace part of their ancestry to six women whose descendants immigrated around 20,000 years ago, a DNA study suggests. Those women left a particular DNA legacy that persists to today in about 95 percent of Native Americans, researchers said. The finding does not mean that only these six women gave rise to the migrants who crossed into North America from Asia in the initial populating of the continent, said study co-author...

    A re-dating of mastodon bones reveals that the extinct mammals, related to the modern day elephant, disappeared from the area during a glacial period more than 50,000 years earlier than previously thought. Existing age estimates of American mastodon fossils indicate that these extinct relatives of elephants lived in the Arctic and Subarctic when the area was covered by ice caps—a chronology that is at odds with what scientists know about the massive animals' preferred habitat: forests and wetlands abundant with leafy food... Over the course of the late Pleistocene, between about 10,000 and 125,000 years ago, the American mastodon (Mammut...

    An archaeologist says it remains a mystery how a circle of stones initially arrived at the floor of Michigan's Grand Traverse Bay. Underwater archeologist Mark Holley said while he first discovered the underwater stones in 2007, no one has been able to prove whether the rocks were placed there by nature or by mankind, the Chicago Tribune reported Sunday. "The first thing I said when I came out of the water was, 'Oh no, I wish we wouldn't have found this,'" Holley said of his discovery. "This is going to invite so much controversy that this is where we're going...

    Biologists briefly brought the extinct Pyrenean ibex back to life in 2003 by creating a clone from a frozen tissue sample harvested before the goat's entire population vanished in 2000. The clone survived just seven minutes after birth, but it gave scientists hope that "de-extinction," once a pipedream, could become a reality. Ten years later, a group of researchers and conservationists gathered in Washington, D.C., today (March 15) for a forum called TEDxDeExtinction, hosted by the National Geographic Society, to talk about how to revive extinct animals, from the Tasmanian tiger and the saber-toothed tiger to the woolly mammoth and...

    An 11-year-old Russian boy stumbled across the 30,000-year-old remains of a woolly mammoth, an experience that was surely either incredibly exciting or permanently traumatising. According to the Moscow News, Yevgeny Salinder found the 500-kilogram beast in the tundra of the Taymyr peninsula in northern Russia. Scientists laboured for a week with axes and steam to dig it out of the permafrost it's been encased in for centuries. Woolly mammoths have been found in the permafrost in Siberia since at least 1929, but this is one of the best preserved. Its tusks, mouth and rib cage are clearly visible....

    Although human hunting played a part in the demise of the woolly mammoth about 10,000 years ago, homo sapiens were but bit players in a global drama involving climate change, comet impact and a multitude of other factors, scientists have found in separate studies. Previous research had blamed their demise on tribal hunting. But new findings “pretty much dispel the idea of any one factor, any one event, as dooming the mammoths,” said Glen MacDonald, a researcher and geographer at the University of California in Los Angeles, to LiveScience.com. In other words, hunting didn’t help, but it was not instrumental....

Some of the curly tusked animals would have sported dark brown coats, while others had pale ginger or blond hair. The information was extracted from a 43,000-year-old woolly mammoth bone from Siberia using the latest genetic techniques. Writing in the journal Science, the researchers said a gene called Mc1r was controlling the beasts' coat colours. This gene is responsible for hair-colour in...

    A ginger-haired mammoth baby found in Siberia could have been snatched by hungry human hunters from the jaws of a lion 10,000 years ago. The body of the beast - the first ever found with its distinctive 'strawberry blonde' hair - has been described as being of 'huge' significance. It's could be evidence that ancient humans attacked and fed on mammoths in Siberia, with the body of 'Yuka' showing wounds consistent with an attack by lions AND people.

    Scientists in search of ancient tusks made a startling discovery. They uncovered the nearly perfectly preserved remains of a woolly mammoth in northern Siberia. The juvenile mammoth is believed to be more than 10,000 years old, but was only 3 to 4 years old when it died. It is unlike any other mammoth that has been unearthed before. The scientists reveal their discovery, which they named "Yuka," in a BBC documentary. Yuka has strawberry blond hair, unlike the dark hair that other mammoths have been found to have. Plus, Yuka's footpads are incredibly well preserved, but some of his bones...

    Scientists, it's said, behave more like lawyers than philosophers. They do not so much test their theories as prosecute their cases, seeking supportive evidence and ignoring data that do not fit—a failing known as confirmation bias. They then accuse their opponents of doing the same thing. This is what makes debates over nature and nurture, dietary fat and climate change so polarized. But just because the prosecutor is biased in favor of his case does not mean the defendant is innocent. Sometimes biased advocates are right. An example of this phenomenon is now being played out in geology over the...

    A juvenile mammoth, nicknamed "Yuka," was found entombed in Siberian ice near the shores of the Arctic Ocean and shows signs of being cut open by ancient people. The remarkably well preserved frozen carcass was discovered in Siberia as part of a BBC/Discovery Channel-funded expedition and is believed to be at least 10,000 years old, if not older. If further study confirms the preliminary findings, it would be the first mammoth carcass revealing signs of human interaction in the region. The carcass is in such good shape that much of its flesh is still intact, retaining its pink color. The...

    An exceedingly well preserved juvenile mammoth carcass has been found in Siberia near the Arctic Ocean and it shows signs of having been attacked by a cave lion and then partially butchered by humans. Dubbed Yuka by the Mammuthus organization, which is studying the remains, the six foot long creature was believed to have been a year and a half to perhaps three or four years old at the time of its death. The mammoth was found by tusk hunters in Northern Siberia, who then turned it over to scientists with the Mammuthus organization. The BBC and Discovery have been...

    We report the discovery in Lake Cuitzeo in central Mexico of a black, carbon-rich, lacustrine layer, containing nanodiamonds, microspherules, and other unusual materials that date to the early Younger Dryas and are interpreted to result from an extraterrestrial impact. These proxies were found in a 27-m-long core as part of an interdisciplinary effort to extract a paleoclimate record back through the previous interglacial. Our attention focused early on an anomalous, 10-cm-thick, carbon-rich layer at a depth of 2.8 m that dates to 12.9 ka and coincides with a suite of anomalous coeval environmental and biotic changes independently recognized in other...

Their results may change the way people think about fossil preservation and present a new method for studying diseases in which identification of proteins is important, such as cancer. When an animal dies, protein immediately begins to degrade and, in the case of fossils, is slowly replaced by mineral. This substitution process was thought to be complete by 1 million years.
