Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years.The record, trapped within the top 20 meters (65.6 feet) of a 400-meter (1,312-foot) sediment core drilled in 2005 in the North Atlantic Ocean by the Integrated Ocean Drilling Program, gives new information about the four glacial cycles that occurred during that period.The new research was presented today at the Chapman Conference on...

In 1996, an international team of scientists led by the University of Zaragoza (UNIZAR) started to carry out a paleontological survey in the cave of El Mir³n. Since then they have focused on analysing the fossil remains of the bones and teeth of small vertebrates that lived in the Cantabrian region over the past 41,000 years, at the end of the Quaternary. The richness, great diversity and good conservation status of the fossils have enabled the researchers to carry out a paleoclimatic...

U.S.-led researchers say they have determined the ancestors of American Indians migrated to the New World from one ancestral Asian population. The international group of scientists said their genetic studies support virtually without exception the single ancestral population theory. The scientists, led by Noah Rosenberg of the University of Michigan, scrutinized DNA samples of people from 31 modern-day Asian populations, 19 Native American, one Greenlandic and two western Beringian...

Ice ages are the greatest natural climate changes in recent geological times. Their rise and fall are caused by slight changes in the Earth's orbit around the Sun due to the influence of the other planets. But we do not know the exact relationship between the changes in the Earth's orbit and the changes in climate. New research from the Niels Bohr Institute indicates that there can be changes in the CO2 levels in the atmosphere that suddenly reach a critical turning point and with that...

U.S. and Chinese scientists say they've determined the Peking Man is thousands of years older than thought. A dating method developed by Purdue University Professor Darryl Granger not only produced a more accurate determination of the age of the Zhoukoudian, China, site of remains of Homo erectus, commonly known as Peking Man, but officials said it also suggests he somehow adapted to the cold conditions produced by a mild glacial period. The site was found to be 680,000-780,000 years old,...

 A new dating method has found that "Peking Man" is around 200,000 years older than previously thought, suggesting he somehow adapted to the cold of a mild glacial period.A dating method developed by a Purdue University researcher allowed a more accurate determination of the age of the Zhoukoudian, China, site of remains of Homo erectus, commonly known as "Peking Man." The site was found to be 680,000-780,000 years old. Earlier estimates put the age at 230,000-500,000 years old.Darryl...

Chinese researchers say a new and more accurate dating method shows that Peking Man may be 200,000 years older than what experts previously thought, The Associated Press reported. The bones of the so-called Peking Man "” a batch of Homo erectus fossils found in the 1920s during cave excavations near Beijing "” were originally believed to have been some 550,000 years old. Researchers have now developed a new method that examines the radioactive decay of aluminum and beryllium in...

Ancient footprints discovered near Ileret in northern Kenya show that some of the earliest humans walked like us and did so on anatomically modern feet more than a million years ago, the Associated Press reported. A Rutgers field school group of mostly American undergraduates excavated the site yielding the footprints, dated to between 1.51 million and 1.53 million years ago, researchers reported in the journal Science. The researchers said the prints indicate a modern upright stride with a...

In Los Angeles, scientists are studying the largest known cache of fossils from the ice age. Researchers from the George C. Page Museum at the La Brea Tar Pits expect the cache to double the size of the museum's ice age collection, which is currently the world's largest, according to the LA Times. Since 1906, more than one million bones have been found at the historic site. Scientists have already reported the discovery of a skull of an American lion and bones of saber-toothed cats, dire...

An article published in the prestigious science magazine Nature Geoscience yesterday shows that the period towards the end of the ice age was engraved by extreme and short-lived variations, which finally terminated the ice age. A group of scientists at the Bjerknes Centre for Climate Research and the University of Bergen in Norway, together with colleagues at ETH, Zrich, combined terrestrial and marine proxy palaeo-data covering the latest part of the ice age to improve our understanding of...

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
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....
