Climate In Arctic More Vulnerable Than Thought
2012-06-25 10:10:11

First analyses of the longest sediment core ever collected on land in the terrestrial Arctic provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years First analyses of the longest sediment core ever collected on land in the terrestrial Arctic, published this week in Science, provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million...

Deglaciation Data Opens Door For Earlier First Americans Migration
2012-06-25 04:06:21

A new study of lake sediment cores from Sanak Island in the western Gulf of Alaska suggests that deglaciation there from the last Ice Age took place as much as 1,500 to 2,000 years earlier than previously thought, opening the door for earlier coastal migration models for the Americas. The Sanak Island Biocomplexity Project, funded by the National Science Foundation, also concluded that the maximum thickness of the ice sheet in the Sanak Island region during the last glacial maximum was 70...

Could Neanderthals Have Been the First Cave Artists?
2012-06-15 07:10:15

By using a new cutting-edge dating technique, researchers have discovered that the practice of painting cave art started as early as 40,000 years ago, or 10,000 years earlier than previously believed. A team of British, Spanish and Portuguese researchers, led by Dr. Alistair Pike of the University of Bristol, investigated some 50 paintings in 11 different caves in northern Spain. Since the paintings had no organic pigment, they could not use radiocarbon dating to determine their age, so...

Eemian Period Is A Poor Analogue For Current Climate Change
2012-06-15 04:34:14

The Eemian interglacial period that began some 125,000 years ago is often used as a model for contemporary climate change. In the international journal “Geophysical Research Letters” scientists from Mainz, Kiel and Potsdam (Germany) now present evidence that the Eemian differed in essential details from modern climatic conditions. Joint press release of the Academy of the Sciences and the Literature Mainz and the GEOMAR | Helmholtz Centre for Ocean Research Kiel. To address...

World's Oldest Musical Instruments Discovered
2012-05-27 04:54:32

According to a new paper published in the latest edition of the Journal of Human Evolution, researchers from Germany and the UK claim that they have identified the oldest known musical instruments on Earth. The research, conducted by experts from Oxford University and Tuebingen University, used carbon dating to discover that flutes crafted from the bones of birds and ivory from mammoth tusks were from between 42,000 and 43,000 years old, BBC News reported on Friday. The flutes, which...

Deep sediments are unparalleled record of biotic changes over past 200,000+ years University of California, Berkeley, scientists are drilling into ancient sediments at the bottom of Northern California's Clear Lake for clues that could help them better predict how today's plants and animals will adapt to climate change and increasing population. The lake sediments are among the world's oldest, containing records of biological change stretching back as far as 500,000 years. The core...

Caltech Researchers Use Stalagmites To Study Past Climate Change
2012-05-04 05:39:29

There is an old trick for remembering the difference between stalactites and stalagmites in a cave: Stalactites hold tight to the ceiling while stalagmites might one day grow to reach the ceiling. Now, it seems, stalagmites might also fill a hole in our understanding of Earth's climate system and how that system is likely to respond to the rapid increase in atmospheric carbon dioxide since preindustrial times. Many existing historical climate records are biased to the high latitudes–...

Mammal Diversity Aided In Survival Over Deep Time
2012-04-24 12:24:49

Lawrence LeBlond for RedOrbit.com In a first of its kind study, researchers from Vanderbilt University found that mammals´ best defense to adapting to climate change was diversity, and families with higher taxonomic diversity were better able to survive ongoing environmental changes. Larisa R. G. DeSantis, Assistant Professor of Earth and Environmental Sciences at Vanderbilt, led researchers in studying how North American mammals adapted to climate change over a 56-million-year...

'Inhabitants Of Madrid' Ate Elephants’ Meat And Bone Marrow 80,000 Years Ago
2012-04-24 08:32:40

Humans that populated the banks of the river Manzanares (Madrid, Spain) during the Middle Palaeolithic (between 127,000 and 40,000 years ago) fed themselves on pachyderm meat and bone marrow. This is what a Spanish study shows and has found percussion and cut marks on elephant remains in the site of Preresa (Madrid). In prehistoric times, hunting animals implied a risk and required a considerable amount of energy. Therefore, when the people of the Middle Palaeolithic (between 127,000 and...

Ice Sheet Collapse And Sea-level Rise At The Bølling Warming 14,600 Years Ago
2012-04-06 04:23:00

International scientists have shown that a dramatic sea-level rise occurred at the onset of the first warm period of the last deglaciation, known as the Bølling warming, approximately 14,600 years ago. This event, referred to as Melt-Water Pulse 1A (MWP-1A), corresponds to a rapid collapse of massive ice sheets 14,600 years ago and resulted in global sea-level rise of ~14 m. These findings are published in the 29 March 2012 issue of the journal Nature (Volume 483, Issue 7391)....

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....
