Woolly mammoth extinction "not linked to humans"

2010-08-17 - Durham, United Kingdom. Pallab Ghosh

Woolly mammoths died out because of dwindling grasslands - rather than being hunted to extinction by humans, according to a Durham University study. After the coldest phase of the last ice age 21,000 years ago, the research revealed, there was a dramatic decline in pasture on which the mammoths fed.

Mammoth blood protein resurrected by scientists

2010-05-04 - Winnipeg, Canada. Paul Rincon

Scientists have discovered genetic mutations that allowed woolly mammoths to survive freezing temperatures. Nature Genetics reports that scientists "resurrected" a mammoth blood protein to come to their finding.
This protein, known as haemoglobin, is found in red blood cells, where it binds to and carries oxygen. The team found that mammoths possessed a genetic adaptation allowing their haemoglobin to release oxygen into the body even at low temperatures. The ability of haemoglobin to rel...

The Mammoths in Spain Lived Mainly on the Plains

2009-10-29 - New Jersey, United States. Brian Switek

As strange as it might seem, the living African and Asian elephants are only the remnants of what was once a very diverse array of proboscideans. In the not-too-distant past elephants and their closest relatives occupied Africa, Europe, Asia, North America, Central America, and South America, but almost all of them had perished by about 10,000 years ago.* Of these recently-extinct forms the most iconic was the woolly mammoth, Mammuthus primigenius, which was covered in long coats of shaggy hair....

Did Dryas comet really kill off mammoth?

2009-10-23 - Portland, United States.

Debate on the existence of a Younger Dryas comet impact, 12,900 years ago, and whether it is linked to mass extinctions of large mammals and early humans in North America reopened this week. This then wiped out such Pleistocene megafauna as the sabre-toothed cat, the mastodon and the mammoth, along with the Clovis people, one of the earliest American cultures.

Scan of PRI fossil may hold elephant key

2009-08-21 - Ithaca, United States.

A CT scan of artifacts held by the Paleontological Research Institution could be the key to unlocking the evolutionary mystery of elephant legs. On Tuesday, curators from the Museum of the Earth and medical professionals from Cayuga Medical Center will take a look inside the leg bones of a mastodon skeleton at the museum with a CT scan. What they find will help advance research into the evolutionary path that has led to elephants unusual structure, said biologist John Hutchinson, a reader in evo...

Mammoth-killing comet questioned

2009-01-29 - London, United Kingdom. Jason Palmer, BBC

A study of wildfires after the last ice age has cast doubt on the theory that a giant comet impact wiped out woolly mammoths and prehistoric humans. Analysis of charcoal and pollen records from around 13,000 years ago showed no evidence of continental-scale fires the cometary impact theory suggests.

Five things you might not know about ...Mammoth comeback

2008-11-22 - Pennsylvania, United States.

Scientists are a decade or two away from recreating the extinct woolly mammoth, according to a Pennsylvania State University researcher. The Colombian mammoth, the southern cousin of the woolly mammoth, roamed the eastern New Mexico plains up to 10,000 years ago. Matt Hillsman, the curator of Eastern New Mexico Universitys Blackwater Draw Museum, said remains of the Colombian mammoth were found at the Black Water Draw dig site.

Houston Zoo Holds Memorial for Baby Elephant "Mac"

2008-11-15 - Houston, United States.

The Houston Zoo family came together Saturday to remember the 2-year-old elephant known as Mac. Mac, the largest Asian elephant born in captivity at 384 pounds, died last Sunday after contracting elephant herpesvirus. Staff and supporters of the zoo gathered at the McNair Asian Elephant Habitat to remember the loss. In a press release, the zoos spokesman thanked the public for their outreach during the difficult time.

Woolly-mammoth gene study changes extinction theory

2008-06-10 - Pennsylvania, United States.

A large genetic study of the extinct woolly mammoth has revealed that the species was not one large homogenous group, as scientists previously had assumed, and that it did not have much genetic diversity. "The population was split into two groups, then one of the groups died out 45,000 years ago, long before the first humans began to appear in the region," said Stephan C. Schuster, associate professor of biochemistry and molecular biology at Penn State and a leader of the research team. "This di...
