Climate Changes After Mass Extinction Modeled By Researchers
2012-12-22 07:09:20

While it has long been assumed plant and animal life took a long time to recover following the largest mass extinction to date, researchers from the University of Zurich have discovered new evidence to suggest they may have bounced back sooner than previously believed.

Cretaceous Extinction Worsened By Ecosystem Structures
2012-10-30 04:17:18

A mass extinction, wiping out numerous species including the dinosaurs, marked the end of the Cretaceous Period. A new study reveals that the structure of North American ecosystems made the extinction worse than it might have been.

Permian Extinction Was Beginning Of 5-Million-Year Deadly Heat Wave

Life about 250 million years ago was hard to come by. In fact, it was nearly non-existent. Scientists, studying why this period, known as the end-Permian event, lasted so long and have found a key ingredient: heat.

Early Evolution Linked To Climate Change And Oxygen Levels
2012-09-28 11:50:55

Geochemists from the University of California, Riverside teamed up with an international team of scientists to uncover new evidence linking together extreme climate change, elevation of oxygen levels and early animal evolution.

Clovis Impact Theory Back Under The Microscope
2012-09-19 04:41:40

Disregard of three critical protocols explains why a group challenging the theory of a North American meteor-impact event approximately 12,900 years ago failed to find iron and silica rich magnetic particles in the sites they investigated.

Dinosaur Extinction Event Wasn't The First
2012-09-06 07:58:40

Sixty-five million years ago, the most studied mass extinction in Earth's history happened and the dinosaurs were wiped off the planet, but a new study indicates that a separate extinction came shortly before that.

Ancient Asteroid Crater Discovered

Asteroid impact craters are found all over the Earth, but most are erased by erosion or covered by time. The date has moved a billion years back by the discovery of the oldest impact crater yet at 3 billion years old.

A basic tenet underpinning scientists' understanding of extinction is that more abundant species persist longer than their less abundant counterparts, but a new University of Georgia study reveals a much more complex relationship.

Some Dinosaurs Were Already Dying Out Before Asteroid Impact
2012-05-02 04:49:27

An asteroid impact may have ended the reign of the dinosaurs here on Earth about 65 million years ago, but new evidence suggests many of the large, plant-eating dinosaurs were already dying out during the last 12 million years of the Cretaceous period.

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

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.


Word of the Day
adustion
  • The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
  • In medicine, cauterization.
