Almost two million years ago, early humans began eating food such as crocodiles, turtles and fish "“ a diet that could have played an important role in the evolution of human brains and our footsteps out of Africa, according to new research. In what is the first evidence of consistent amounts of aquatic foods in the human diet, an international team of researchers has discovered early stone tools and cut marked animal remains in northern Kenya. The work has just been published in the...

The balance of biodiversity within North American small-mammal communities is so out of whack from the last episode of global warming about 12,000 years ago that the current climate change could push them past a tipping point, with repercussions up and down the food chain, say Stanford biologists. The evidence lies in fossils spanning the last 20,000 years that the researchers excavated from a cave in Northern California. What they found is that although the small mammals in the area suffered...

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...

The scientists who discovered the remains of an ancient hobbit-like species of hominid have discovered that the species may have colonized the Indonesian island of Flores as much as a million years ago - far earlier than was first expected - according to a study published on Wednesday. Archaeologist Dr. Adam Brumm, who led the expedition that first discovered the skeletal remains of the diminutive Homo floresiensis on the isle of Flores in 2003, has published in the scientific journal...

A team of scientists has discovered that the drastic decline in Arctic musk ox populations that began roughly 12,000 years ago was due to a warming climate rather than to human hunting.  "This is the first study to use ancient musk ox DNA collected from across the animal's former geographic range to test for human impacts on musk ox populations," said Beth Shapiro, the Shaffer Career Development assistant professor of biology at Penn State University and one of the team's leaders. ...

For decades, the study of evolution has focused on the continent of Africa, the home of the majority of hominid fossils and the place where Homo erectus originated. However, the 2003 discovery of Homo floresiensis in Indonesia, and recent claims by researchers that it is indeed a new species of human, is challenging what scientists know about the origins of humanity. "This is a new species that cannot be explained by any known pathology," Dr. William L. Jungers told the Associated Press (AP)...

Homo floresiensis, a pygmy-sized small-brained hominin popularly known as 'the Hobbit' was discovered five years ago, but controversy continues over whether the small brain is actually due to a pathological condition. How can its tiny brain size be explained? Researchers writing in the open access journal BMC Biology have tackled this question in the context of a comprehensive assessment of the evolution of brain and body size throughout the larger primate family. Nick Mundy and Stephen...

A new scientific paper co-authored by a University of Adelaide researcher reports strong evidence that humans, not climate change, caused the demise of Australia's megafauna - giant marsupials, huge reptiles and flightless birds - at least 40,000 years ago. In a paper published today in the international journal Science, two Australian scientists claim that improved dating methods show that humans and megafauna only co-existed for a relatively short time after people inhabited Australia,...

Woolly mammoths and prehistoric horses grazed on the North American plains for several thousand years longer than hitherto assumed This is shown by samples of ancient DNA, analyzed by an international team of research scientists under the leadership of Professor Eske Willerslev from Copenhagen University. Analyses of ancient DNA thereby once again revoke results of more common methods of dating, such as carbon 14 analysis of bone and tooth remains from extinct animals. These methods which had...

University of Alberta researchers are part of an international team that has used DNA samples from frozen dirt, not fossilized bones, to revise the history of North America's woolly mammoths and ancient horses. The work of U of A Earth and Atmospheric Sciences professor Duane Froese and his colleagues counters an important extinction theory, based on radiocarbon dating of bones and teeth. That analysis concluded that more than half of the large mammals in North America (the 'megafauna')...

Australopithecus garhi
2013-11-29 11:38:51

Australopithecus garhi is a gracile australopithecine species whose fossils were discovered in 1996 by a research team led by Ethiopian paleontologist Berhane Asfaw ad Tim White, an American paleontologist. The remains are believed to be a human ancestor species and most likely the direct ancestor to the human genus Homo. Tim White was the scientist to find the first of the key A. garhi fossils in 1996 within the Bouri Formation found in the Middle Awash of Ethiopia’s Afar Depression....

Homo floresiensis
2013-09-16 13:06:40

Homo floresiensis Homo floresiensis, or Flores Man, nicknamed “hobbit” and “Flow”, is an extinct species in the genus Homo. The remains of an individual that would have stood about 3 feet in height were uncovered in 2003 on the island of Flores in Indonesia. Incomplete skeletons of nine individuals have been recovered, including one complete cranium. These remains have been the focus of intense research to establish whether they represent a species distinctive from modern humans....

Panthera leo spelaea

Commonly known as the Eurasian cave lion or the European cave lion, Panthera leo spelaea is an extinct subspecies of lion. It is thought to have lived during the Pleistocene epoch, and may have lived in the Balkans in southeastern Europe until 2,000 years ago. The range of this cave lion would have included northwestern North America, Asia, and areas of Europe and would have extended from Germany, Spain, and Great Britain to the Yukon Territory. Its range also extended from Turkistan to...

Stag-Moose, Cervalces scotti
2012-05-11 12:12:45

The stag-moose (Cervalces scotti) is also known as the stag moose and was actually a deer that resembled a moose. It resided in North America during the Pleistocene era. Its range included New Jersey and Iowa, reach north from Arkansas to Southern Canada. It inhabited wetlands in these areas. This animal had long legs, a head resembling an elk, and huge, complex antlers. The stag-moose became extinct during the mass extinction of large mammals that occurred in the last Ice Age on North...

Shrub-ox, Euceratherium collinum
2012-05-10 05:18:10

The shrub-ox (Euceratherium collinum) is a close relative of the modern musk-ox, and is an extinct member of the family Bovidae. It inhabited North America during the late Pleistocene, appearing before the first bovids entered North America from Eurasia. These muskoxen became extinct approximately 11,500 years ago. The shrub-ox was very large, approximately in between the sizes of a musk-ox and an American Bison. Research done on pellets left by these oxen shows that they browsed for food...
