Saber-tooth Cats In The Late Pleistocene May Not Have Starved
2012-12-27 06:30:23

April Flowers for redOrbit.com - Your Universe Online A new study, led by Vanderbilt University, reveals that American lions and saber-toothed cats that roamed the North American continent in the last Pleistocene were living well off the fat of the land. The results of this study, published in PLOS ONE, were gathered from microscopic wear patterns on the teeth of these great cats recovered from the La Brea Tar Pits in southern California. The study, contrary to prior analysis, did not...

New Hints Into Human Ancestry Could Lead To Rethink The 'Out Of Africa' Theory
2012-12-14 12:04:20

Brett Smith for redOrbit.com - Your Universe Online Research and excavations by a Canadian researcher from sites in southern Tanzania could lead to a rethinking of the ℠Out of Africa´ narrative that describes the human diaspora around the globe, according to a new report in the journal Quaternary International. Led by Pamela Willoughby, the Iringa Region Archaeological Project has uncovered artifacts that suggest a constant human occupation between today and at least...

Early African Homo Sapiens Were First Technologically Advanced People
2012-12-06 12:56:14

April Flowers for redOrbit.com - Your Universe Online Africa, and especially South Africa, is one-step closer to being confirmed as the primary center for the early development of human behavior. Scientists have searched for the origin of modern human behavior and technological advancement among our early African ancestors for a long time. Wits University archaeologist Christopher Henshilwood, along with a team of international researchers, has published the first detailed summary...

Native Americans, Northern Europeans Genetically Related
2012-12-01 11:17:42

April Flowers for redOrbit.com — Your Universe Online Northern European populations - including British, Scandinavians, French and some Eastern Europeans - descend from a mixture of two very different ancestral populations a new study finds, and one of these populations is related to Native Americans. The results of this study, published in the November issue of the Genetics Society of America's journal GENETICS, help fill in the gaps in scientific understanding of both Native...

The origin and dispersal of modern humans and modern human behavior are key interests in Paleolithic archaeology and anthropology. Engraved objects are usually seen as a hallmark of cognition and symbolism, which are viewed as important features of modern human behavior. In recent years, engraved ochre, bones and ostrich eggs unearthed from various Paleolithic sites in Africa, the Near East and Europe have attracted the attention of many scholars. However, such items are rarely...

Spear Tips Were Used A Half Million Years Ago
2012-11-16 06:26:11

April Flowers for redOrbit.com - Your Universe Online A team of anthropologists, led by the University of Toronto, has found evidence that human ancestors used stone tipped weapons for hunting 500,000 years ago. This is 200,000 years earlier than previously thought, according to the new study published in Science. "This changes the way we think about early human adaptations and capacities before the origin of our own species," says Jayne Wilkins, a PhD candidate in the Department of...

What Triggered Earth's Last Big Freeze
2012-11-06 09:53:08

April Flowers for redOrbit.com - Your Universe Online Climate scientists have long debated whether floodwaters from melting of the Laurentide Ice Sheet flowed northwest into the Arctic first, or east via the Gulf of St. Lawrence to weaken ocean thermohaline circulation and have a frigid effect on global climate. This debate concerning the melt, which ushered in the last major cold episode about 12,900 years ago, has been raging for about 30 years. A research team from the University of...

Ancient Climate Change Made Hippos Smaller
2012-10-26 11:14:29

April Flowers for redOrbit.com - Your Universe Online Have you heard of giant hippopotamuses wandering along the banks of the Elbe in Germany lately? They are not a common sight today, that is for sure, but 1.8 million years ago, hippos were a prominent part of European wildlife along with other megafauna such as woolly mammoths and giant cave bears. A new study by paleontologists, published in the journal Boreas, claims that the changing climate during the Pleistocene may have forced...

Atlantic Heat Pump Was Once Faster
2012-10-16 13:39:01

April Flowers for redOrbit.com - Your Universe Online A new study from an international team of scientists led by environmental physicists at Heidleberg University in Germany suggests that the circulation of the Atlantic Ocean was faster during the last Ice Age than today. It has long been assumed that heat transport in the Atlantic Ocean during the last Ice Age was weaker, but according to the new data, it appears that it was actually stronger than it currently is. The team used...

Desert Climate In West US Affected By Ancient Water Cycle
2012-09-28 09:06:29

Alan McStravick for redOrbit.com - Your Universe Online The climate change we are currently experiencing, while disconcerting and increasingly uncomfortable, is not unprecedented when viewed through the historical prism of life on Earth. A study led by researchers from Texas A&M University's Department of Oceanography looks back at the water cycle that affected the Western United States in an era dating back some 20,000 years. Focusing on the deserts of  Utah and Nevada,...

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....

Neanderthals
2013-10-03 16:03:35

The Neanderthals or Neandertals are an extinct species or subspecies of the genus Homo which is closely related to modern humans. They are known from fossils, dating back from the Pleistocene period, which have been found in Europe and parts of western and central Asia. The species gets its name from Neandertal, “Neander’s Valley”, the location in Germany where it was first uncovered. Neanderthals are classified either as a subspecies of Homo sapiens or as a distinct species of the...

Homo sapiens
2013-09-24 13:55:52

Homo sapiens is the scientific name for the human species. Homo is the human genus, which also includes Neanderthals and various other extinct species of hominid. H. sapiens is the only surviving species of the genus Homo. Modern humans are the subspecies Homo sapiens sapiens, distinguished from their direct ancestor, Homo sapiens idaltu (http://en.wikipedia.org/wiki/Homo_sapiens_idaltu). Subspecies of H. sapiens include Homo sapiens idaltu, roughly translated as “elder wise human” and...

Homo sapiens idaltu
2013-09-24 12:20:45

Homo sapiens idaltu is an extinct subspecies of Homo sapiens that lived nearly 160,000 years ago during the Pleistocene in Africa. “Idaltu” comes from the Saho-Afar word meaning “elder” or “first born”. The fossilized remains of H. s. idaltu were uncovered at Herto Bouri near the Middle Awash site of Ethiopia’s Afar Triangle in the year 1997 by Tim White, but were first revealed in 2003. Herto Bouri is a portion of Ethiopia under volcanic layers. By using radioisotope dating,...

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....
