Microscopic Diamonds Suggest Cosmic Impact Responsible For Major Period Of Climate Change

Emily Murphy, University of Chicago Press A new study published in The Journal of Geology provides support for the theory that a cosmic impact event over North America some 13,000 years ago caused a major period of climate change known as the...

Chuck Bednar for redOrbit.com - Your Universe Online Neanderthals have a reputation for being unintelligent brutes, but the discovery of a series of lines scratched into a rock wall in southwestern Europe suggests that the predecessors of modern humans might have had the intelligence and creativity to produce cave art. In research published Monday in the Proceedings of the National Academy of Sciences, experts from 11 different European institutions reported discovering the...

Neanderthals and Modern Man
2014-08-21 07:47:02

redOrbit Staff & Wire Reports - Your Universe Online Neanderthals died out approximately 10,000 years earlier than previously believed, due in part to the fact that modern humans arrived in Europe sooner than originally thought, an international team of researchers reported Wednesday in the journal Nature. Professor Thomas Higham of the University of Oxford and his colleagues obtained new radiocarbon dates for roughly 200 bone, charcoal and shell samples from 40 important European...

Homo floresiensis

redOrbit Staff & Wire Reports - Your Universe Online Skeletal remains recovered from the Indonesian island of Flores over a decade ago are not a new species of “hobbit” sized human, but an ancient Homo sapien showing signs of abnormal development consistent with Down syndrome, an international team of researchers claim in a new Proceedings of the National Academy of Sciences study. According to NBC News, the 15,000-year-old fossil identified as LB1 had previously been determined...

Long-Term Climate Factors Led Early Humans To Patchwork Evolution
2014-07-04 11:14:48

Brett Smith for redOrbit.com - Your Universe Online In the past, scientists concluded many of man’s defining qualities, such as legs made for walking upright and a large brain, evolved all at once. But according to a new study in the journal Science, shifts in climate caused these qualities to evolve separately. Based on analyses of fossil evidence, the study researchers said the shrinking of forests and expansion of savannas in East Africa led to walking upright, which freed our...

redOrbit Staff & Wire Reports - Your Universe Online A gene acquired from an extinct cousin of modern humans is responsible for helping Tibetans adapt to high altitudes, according to new research published online by the weekly science journal Nature on Wednesday. Scientists from the University of California, Berkeley and Chinese genomics organization BGI-Shenzen found that Tibetans acquired the ability when their ancestors mated with Denisovans or individuals related to the...

“Mosaic Pattern” Of Cranial Evolution Supported By Study Of Neanderthal Skulls In Spain
2014-06-20 08:27:46

redOrbit Staff & Wire Reports – Your Universe Online Analysis of several skulls found in a Spanish cave reveal that the trademark facial features of the Neanderthals appeared prior to their braincases, lending new support to the “mosaic pattern” theory that the long extinct human predecessors did not evolve their defining characteristics all at the same time. The study, which appears in the journal Science, uses new data obtained from 17 fossilized human skulls obtained from...

explaining the Last Glacial Maximum

redOrbit Staff & Wire Reports - Your Universe Online A team of MIT scientists has turned to the Southern Ocean in search of an explanation for the Last Glacial Maximum (LGM), a period in the Earth's climate history during which the northern continents were covered by ice sheets, according to new research appearing in the Proceedings of the National Academy of Sciences. Plankton fossils in deep-sea sediments contain chemical traces that reveal rearranged ocean water masses, as well...

Antarctic Ice Sheet Became Unstable At The End Of The Last Ice Age
2014-05-29 05:20:26

redOrbit Staff & Wire Reports - Your Universe Online The Antarctic Ice Sheet started melting approximately 5,000 years earlier than previously believed following the last ice age, according to new research appearing in this week’s edition of the journal Nature. The study, which comes in the wake of research suggesting that destabilization of some of the West Antarctic Ice Sheet has already begun, also said that the shrinkage of the ice sheet accelerated and caused rapid sea level...

Most Complete Ancient Skeleton From New World Sheds New Light On Human Migration
2014-05-16 07:33:27

Lawrence LeBlond for redOrbit.com - Your Universe Online An international team of scientists have uncovered the most genetically complete human skeleton from the New World yet, dating back more than 12,000 years. The skeleton, discovered in an underwater cave system in the Yucatan Peninsula, is that of a 12-year-old girl who fell into the once dry open pit, breaking her pelvis and likely killing her instantly from the 190-foot fall, according to researchers. Now, the team, a body of...

Study Questions Younger Dryas Event Comet Theories
2014-05-14 07:31:39

April Flowers for redOrbit.com – Your Universe Online Approximately 128,000 years ago, near the end of the last Ice Age, there was a brief episode of glacial conditions called the Younger Dryas event. The Younger Dryas, named for a flower that flourished during this time, lasted about 1,000 years. There has been quite a bit of controversy in the scientific community regarding what might have initiated the event—with a wide range of theories, including one that has the event caused by...

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

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

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....
