Exploding stars in near-solar space may have triggered at least two mass extinction events in Earth's history. An analysis of the frequency of supernova explosions in the Milky Way, led by ...

Add Yahoo as a preferred source to see more of our stories on Google. Sharks might be the all time bullet-dodging champions. They’ve been around for about 450 million years, longer than trees, longer ...

Supernova destroying planet, illustration. A rocky planet lies in the wake of its star, which has just gone supernova. The explosion shatters the planet. A complete census of massive stars in our part ...

Everyone knows that dinosaurs are extinct, and most people have some idea about how it might have occurred. But the exact periods in history when it happened are less well known. Was it a single ...

Most people think of crocodilians as living fossils—stubbornly unchanged, prehistoric relics that have ruled the world's swampiest corners for millions of years. But their evolutionary history tells a ...

The Silurian Period is characterised by a dynamic interplay between environmental stressors and biotic turnover, with extinction events and carbon isotope excursions (CIEs) representing pivotal ...

Crocodiles are persistent - not just in their deadly pursuit of prey, but in terms of their existence. The contemporary species hails from a 230-million-year lineage that has survived two mass ...

Many of their descendants—modern birds—are currently threatened by extinction, with hundreds of species at risk due to human activity. This article explores the major extinction events that influenced ...

A pair of Sacabambaspis fish, around 35 cm in length, which had distinct, forward-facing eyes and an armored head. No fossils of animals like Sacabambaspis from after the Late Ordovician Mass ...

Extinction is inevitable. Expected. Almost all (99%) species that have ever existed have died out. Those disappearances have largely occurred at consistent background rates. But in the context of mass ...

However, for extinctions caused by anthropogenic (human) impacts on the environment, there is some concern among scientists that more evolutionary history may be lost than in past extinction events.
