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...

Ancient Mammals Evolution Mass Extinction
2013-08-14 09:52:22

Brett Smith for redOrbit.com - Your Universe Online With the continuous expansion of human activity around the world, many species are facing the increasing threat of extinction as their habitats shrink and shift. Yet life on planet Earth has faced even larger extinction threats in the past. A new study int the journal Proceedings of the Royal Society B examines how a group of mammalian relatives called anomodonts coped with a mass extinction event of the prehistoric past as a way to...

Meteor Impact Crater Found Beneath Iowa Town
2013-07-11 04:39:36

Lee Rannals for redOrbit.com - Your Universe Online A meteor crater from 470-million-years-ago lies buried several hundred feet beneath the town of Decorah, Iowa, according to an airborne geophysical survey reported in EARTH Magazine. Geologists first hypothesized the crater's existence while examining cuttings from water wells drilled near the town. During this examination they discovered evidence of a previously unknown shale deposit that was nearly a perfect circle, roughly 3.4 miles...

Although scientists have known since the middle of the 19th century that the tropics are teeming with species while the poles harbor relatively few, the origin of the most dramatic and pervasive biodiversity on Earth has never been clear. New research sheds light on how that pattern came about. Furthermore, it confirms that the tropics have been and continue to be the Earth's engine of biodiversity. By examining marine bivalves (two-shelled mollusks including scallops, cockles and...

Mass Extinction Made Space Dinosaur Forerunners
2013-04-30 09:47:00

April Flowers for redOrbit.com - Your Universe Online Approximately 252 million years ago, during the world´s largest mass extinction event, nine out of ten species vanished from the planet. Based on fossil records from sites in South Africa and southwest Russia, many scientists have long thought the predecessors of dinosaurs largely missed the race to fill habitat niches that were emptied during this event. However, according to an international team of scientists, it turns out...

Asteroid Caused Massive Firestorm Leading To Global Extinction
2013-03-28 05:17:03

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Colorado claim to have uncovered new evidence supporting the notion that a Manhattan-sized asteroid collided with the Earth some 66 million years ago, triggering a global firestorm that would have led to the extinction of 80 percent of the planet´s species. According to Douglas Robertson of the Cooperative Institute for Research in Environmental Sciences (CIRES) and colleagues, the firestorm...

Comet May Have Caused Chicxulub Crater And Dinosaur Extinction
2013-03-24 05:34:56

Brett Smith for redOrbit.com - Your Universe Online One of the most popular theories on the disappearance of the dinosaurs surrounds the 110 mile-wide Chicxulub crater in Mexico. Many scientists believe the extinction was caused by an asteroid that crashed into Earth, leaving only a massive crater behind. However, a group of American scientists is presenting a theory that the culprit was actually a speeding comet, not a relatively slow-moving asteroid as many theories assert....

Megavolcanoes Led To End-Triassic Extinction Allowing Dinosaurs To Evolve
2013-03-22 04:19:11

WATCH VIDEO: [Drilling Into The Jurassic In New Jersey] Lawrence LeBlond for redOrbit.com - Your Universe Online Popular theory suggests that a massive asteroid smashed into Earth around 65 million years ago wiping most life, including the dinosaurs, off the face of the earth. Now, scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event. An examination of evidence across three continents...

Research Provides New Insight Into Snowball Earth Duration
2013-02-28 21:17:15

Lee Rannals for redOrbit.com — Your Universe Online About 635 million years ago, our world was covered in ice during an event called "Snowball Earth," and new details written in the Proceedings of the National Academy of Sciences provide new insight on the duration of this event. According to the Snowball Earth hypothesis, an ice age brought on rapid changes in the atmospheric conditions on our planet, followed by a rapid greenhouse heat wave. This period may have given rise to...

Extinction Drives Plant Biodiversity As Much As Evolution
2013-02-14 08:57:43

Peter Suciu for redOrbit.com — Your Universe Online German philosopher Friedrich Nietzsche famously said “that which does kill us makes us stronger,” but apparently he didn´t understand the complexities of biodiversity. If he had, he might have noted that extinction could influence biodiversity as much as evolution. This is what researchers at the University of Melbourne and the University of Tasmania have discovered while examining plant diversity in South East...
