Scientists at the University of Cambridge say that many of the large animals that went extinct over the past 100,000 years or so were primarily killed off by a combination of climate change and human activity. Very few such creatures remain today.
Elephants and rhinoceroses are good example of large animals that ma... |

About 450 million years ago, when the Ordovician-Silurian extinction event took place, some 60 percent of all marine invertebrates died out. Researchers analyzing why the phenomenon took place now say that gamma-ray bursts from a nearby star may have had something to do with this.
Scientists agree that some of the E... |

Those who argued strong and loud that comet Elenin would cause catastrophic natural events as it zipped past Earth were brought to silence on Sunday, October 16. Pieces of the object zipped past our planet without ushering in the apocalypse.Some people were convinced that this object was the infamous planet Nibiru, h... |

Paleontologists have recently determined that the end of the Age of Dinosaurs came about abruptly, in one fell swoop, rather than progressively, as other researchers suggested in the past. These conclusions are based on a thorough analysis of a single dinosaur horn. The issue as to whether the extinction of these gia... |

Scientists with the University of California in Los Angeles (UCLA) announce the discovery of a fundamental flaw in the methods used to calculate the rate at which species go extinct. The implication this work has is suggesting that currently-accepted extinction rates are higher than in reality.These rates may in fact... |

Northwestern University physics professor Adilson Motter and his student Sagar Sahasrabudhe announce the development of a new mathematical model, that is capable of detecting potential cascades of events that may lead to the collapse of food networks, and to extinction events.The model was developed as part of a larg... |

Research scientists have over the years developed methods of using the fossil record for studies of the future. The analysis of extinct species is allowing them to gain more insight into how modern-day animals response to changes in their environments and ecosystems, and scientists are on it 24/7.

At about 4.5 billion years old, one could expect Earth to be a lot calmer than it was in its earliest days, but researchers say that this is not the case. Solidified from a ball of hot lava, the planet is now covered by large amounts of water, and is the only celestial body in the known Universe that is capable of su... |

Researchers have recently set forth a very bold new idea on why large flightless birds such as the ostrich lost their ability to fly. The hypothesis holds that, as the dinosaurs went extinct during the K-T event, more than 65 million years ago, they left behind an open niche, which these animals occupied. And, accord... |

According to a growing body of scientific pieces of evidence, it would appear that human activity was the main factor that led to the extinction of some of Australia's greatest animals. Previous investigations into the matter had concluded that climate change and variations in the hydrology and vegetation of the... |

At this point, the human population on Earth has spread across the planet, and built a strong and established civilization that is very unlikely to come to an end soon if we don't make it so. But things weren't always this clear when it came to our species' future, as evidenced by the near-extinction e... |

The generally accepted date for the mammoth's extinction in the international scientific community is sometime around 12,000 years ago, shortly before humans took over the world and learned agriculture. These estimates are based on numerous fossil records, which all show that the last mammoths and mastodons died... |

Our planet has been ruthless to some of the species living on it over the long years of its existence. Extinction events and evolutionary bottlenecks have almost wiped out life on Earth on several occasions, but the culprit has always been nature. Now, it's humans. Excessive hunting and increased pollution are d... |

With the growing threat of global warming and climate change looming ahead, biologists are beginning to plan for the future. A debate is currently raging in the international community as to which way of protecting endangered species and conserving biodiversity is the best. While some believe that local programs appl... |
