In a new study in Geology, researchers calculated how long it took for novel single-celled marine species to appear after the asteroid impact, and it’s surprisingly fast.

Telepathic dogs, eerily topical pandemics, mass infertility. When it comes to zombies, disease, or mass extinction, these ...

During these waves of mass extinction, most vertebrate survivors were confined to refugia, or isolated biodiversity hotspots separated by large areas of deep ocean. In these zones, surviving jawed ...

A massive ice age wiped out ocean life 445 million years ago, reshaping ecosystems and setting the stage for jawed fish evolution.

A new study led by researchers at the University of Oxford has shown that the shape and orientation of coastlines ...

A rapid climate collapse during the Late Ordovician Mass Extinction devastated ocean life and reshuffled Earth’s ecosystems. In the aftermath, jawed vertebrates gained an unexpected edge by surviving ...

A devastating ice age wiped out most marine life, yet new research reveals how this ancient disaster unexpectedly paved the ...

One of Earth’s earliest mass extinctions wiped out most ocean life during a sudden global ice age. From the ruins, jawed vertebrates survived, diversified, and transformed the course of evolution.
