Life-Bearing Oxygen Appeared On Earth Three Billion Years Ago
2013-09-26 07:19:54

April Flowers for redOrbit.com - Your Universe Online New research from the University of Copenhagen and University of British Columbia (UBC) has revealed that oxygen appeared 700 million years earlier than we previously thought. The findings, published in the journal Nature, raises new questions about the evolution of early life. The research team examined the chemical composition of three-billion-year-old soils from South Africa, which are the oldest soils on Earth. They found...

While we grapple with the impact of climate change, archaeologists suggest we spare a thought for Aboriginal Australians who had to cope with the last ice age. "The period scientists call the Last Glacial Maximum, or LGM for short, is the most significant climatic event ever faced by humans on this continent," Associate Professor Sean Ulm from James Cook University in Cairns said. Research recently published in the Journal of Archaeological Science sheds new light on the ways Aboriginal...

Many climate studies have predicted that tree species will respond to global warming by migrating via seed dispersal to cooler climates. But a new study of 65 different species in 31 eastern states finds evidence of a different, unexpected response. Nearly 80 percent of the species aren’t yet shifting their geographic distributions to higher latitudes. Instead, they’re staying in place – but speeding up their life cycles. The Duke University-led study, published online Wednesday...

Ancient Crocodile Diversity
2013-09-11 12:31:02

[ Watch the Video: Crocodiles Thrived During Prehistoric Times ] Brett Smith for redOrbit.com - Your Universe Online Ancient relatives of crocodiles had a wide range of habitats and ecosystems, with some species built like domestic dogs and others built for swimming through the open seas. Using a combination of morphological and biomechanical metrics to analyze these ancient crocodilians, a new study from researchers at the University of Bristol in the UK identified distinct trends...

Earliest Known Scorpion Fossil Discovered In South Africa
2013-09-03 12:41:53

Lee Rannals for redOrbit.com - Your Universe Online Scientists publishing a study in the journal African Invertebrate say they have discovered a 350-million-year-old fossilized scorpion. The specimen, discovered in rocks from the Devonian Witteberg Group near Grahamstown, is a new species of scorpion called Gondwanascorpio emzantsiensis. Dr Robert Gess, from the Evolutionary Studies Institute at Wits University, discovered the specimen, which is said to be the oldest known land-living...

Black Carbon Suspect In Mid-1800s Alps Glacier Retreat
2013-09-03 08:17:32

University of Colorado at Boulder Scientists have uncovered strong evidence that soot, or black carbon, sent into the air by a rapidly industrializing Europe, likely caused the abrupt retreat of mountain glaciers in the European Alps. The research, published Sept. 2 in the Proceedings of the National Academy of Sciences, may help resolve a longstanding scientific debate about why the Alps glaciers retreated beginning in the 1860s, decades before global temperatures started rising again....

End-Permian Mass Extinction Paved Way For Modern Mammals
2013-08-28 16:19:55

Peter Suciu for redOrbit.com - Your Universe Online Mass extinction certainly sounds like it would be the end of the line, and perhaps even evokes images of the end of the world. However, new research conducted by the University of Lincoln, the National Museum in Bloemfontein, South Africa, and the University of Bristol suggests that the end can also be the beginning. This research, which was published this month in the Proceedings of the Royal Society B, noted that the ancient closest...

Last Glacial Maximum Peaked In Spain Much Earlier Than Elsewhere
2013-08-26 14:15:13

Brett Smith for redOrbit.com - Your Universe Online While it’s widely believed that the world’s massive ice sheets were at their greatest extent 20,000 years ago during the last glacial maximum, new research published in Scientific Reports suggested that the glacial peak was much earlier in modern-day Spain. According to study researchers, their findings could inform more localized models of glacier activity and be used to calculate the effects of climate change. “We wanted to...

Hula Painted Frog, Discoglossus nigriventer
2014-08-18 15:55:22

The Hula painted frog was considered extinct by the IUCN since 1996. Very little is known about the species because very few specimens have been found. In 1940 two adults and two tadpoles were collected but the smaller one was eaten by the larger one, and the tadpoles were lost. A single Hula painted frog was found in 1955 which was the last record of this specimen. The extinction of this species is said to be the result of the draining of lake Hula and its marshes in the 1950’s. Only...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

Geologic Clock With Events And Periods
2012-11-18 19:10:56

The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...
