Hydrogen Sulfide Helped Spark Life?
|
| Topic: Origin & Evolution of Life |
03/22/11 |
| In the 1950s, Stanley Miller demonstrated that organic compounds could form under conditions mimicking the primordial Earth. By re-examining some of Miller's unused samples with modern techniques, scientists have found that volcanoes and sulfur may have been important in life's origin on our planet. |

Earth's Sixth Mass Extinction
|
| Topic: Origin & Evolution of Life |
03/06/11 |
| Earth may be on the brink of a mass extinction on the scale of the five global mass extinctions that have occurred during the past 540 million years. The researchers believe that a modern global mass extinction would be the result of climate change and human activities, but they also believe it is not to late to stop it. |
