No Single Factor Behind Cambrian Explosion Of Animal Life
2013-09-20 07:58:01

April Flowers for redOrbit.com - Your Universe Online A new study from the UK reveals that the explosion of animal life on Earth that occurred around 520 million years ago was the result of a combination of interlinked factors, rather than a single underlying cause. Over the past few decades, dozens of individual theories have been put forth for the rapid diversification of animal species in the early Cambrian period. The new study, published in Science, suggests a more holistic...

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...

Land Life Earlier Than Thought

Brett Smith for redOrbit.com - Your Universe Online Conventional theories have placed life on land for the last 500 million years, but a new study from a team of American and Australian researchers might push that back to 2.2 billion years. To support their claim, the scientists presented evidence in the form of tiny newly discovered fossils the size of a match head called Diskagma buttonii that were discovered in ancient soil samples. "They certainly were...

Community colleges provide a strong foundation for the nation's graduating STEM (Science Technology Engineering and Mathematics) workforce. In its latest Geoscience Currents, the American Geosciences Institute documents the flow of geoscience students from 2–year to 4-year institutions in Texas, adding to an earlier report on similar data from California released in 2012. In 2012, 70 percent of geoscience students in Texas public universities had transferred from...

Ancient Fish Fossils Give Insight Into Evolutionary History Of Gobioid Order
2013-05-16 13:51:46

LMU Fish fossils that are about 23 million years old give unprecedented insight into the evolutionary history of the gobioid order, one of the most species-rich groups among the modern bony fishes. Researchers led by paleontologist Professor Bettina Reichenbacher from the Division of Paleontology and Geobiology at LMU´s Department of Earth and Environmental Sciences have completed a comprehensive analysis of fish fossils which they assign to the group of bony fishes that includes...

A team of geoscientists from Southwest Research Institute (SwRI) using newly available remote-sensing technology has achieved unprecedented detail in quantifying subtle, long-period changes in the water levels of shallow lakes and ponds in hard-to-reach Arctic wetlands. Analysis comparing time-lapsed, high-resolution satellite imagery of the Ahnewetut Wetlands in Kobuk Valley National Park, Alaska, revealed an accelerated loss of surface water in shallow thaw lakes and ponds over a recent...

In the March issue of GSA Today, seven scientists from six countries, led by Jan Zalasiewicz of the University of Leicester, propose a realignment of the terms "geochronology" and "chronostratigraphy" in an attempt to resolve the debate of whether units of the Geological Time Scale should have a single (time) or dual (time and time-rock) hierarchy. In their system, which retains both parallel sets of units, with an option to adopt one or other when appropriate, geochronology refers to all...

Environmental Science
2014-01-12 00:00:00

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...

Earth science (or geoscience) is the science of the planet Earth. Earth science can be broken down into four major disciplines, which are: geography, geology, geophysics, and geodesy. These disciplines use physics, chemistry, biology, chronology and mathematics to arrive to a greater understanding of the principal areas of the Earth system. Since Earth is the only known life-bearing planet, Earth science is solely dedicated to the geophysical makeup of our own planet. One discipline,...
