Mass extinction events represent intervals of abrupt, large‐scale loss of biodiversity that have repeatedly reshaped life on Earth. These crises are commonly linked to dramatic environmental ...

Speciation and extinction are the twin engines that have sculpted the diversity of life on Earth. Speciation, the process by which new species arise from ancestral populations, is driven by a mixture ...

The Jurassic Period is one of the three prehistoric geological periods of the Mesozoic Era. It spans from 145 million to 201 million years ago. This period was preceded by the Triassic Period and ...

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 ...

A mass extinction event is a term used to describe a large-scale event that wipes out species. It is usually not a short, one-time incident but rather something that occurs over thousands or millions ...

At least two mass extinction events in Earth's history were likely caused by the "devastating" effects of nearby supernova explosions, a new study suggests. Researchers at Keele University say these ...

Dinosaurs ruled the Earth for over 150 million years. Compared to the mere 4–6 million years that scientists believe humans and their earliest ancestors have been on the planet, it wouldn’t be ...

Waves of extinction have ripped through life on Earth over and over again during its long history. The non-avian dinosaurs ...
