Farther back in our planet’s history, volcanic eruptions, rapid climate change, and plummeting oxygen levels have caused at least four additional mass extinctions, with smaller pulses of biodiversity ...

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

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.

Discover how the first mass extinction put jawed fishes on the map, species that would later come to dominate animal life on ...

Sharks might be the all time bullet-dodging champions. They’ve been around for about 450 million years, longer than trees, longer than the rings of Saturn, and longer than most of the other life on ...

This lineage was widespread and abundant in the Late Cretaceous, but just a few species survive today off the coasts of Australia. If you’re an animal living through a mass extinction, it’s best to be ...

Shocking research has warned that humans are driving extinctions at a scale not seen since the mass extinction of the dinosaurs some 66 million years ago. The researchers from the University of York, ...

A new theory suggests depletion of trace elements in the oceans was a factor in three major mass extinction events in the past 600 million years, according to new research led by Flinders University's ...

The evolution of life on planet Earth has occurred gradually over time, but it has not always been a peaceful process. Life has had to face cataclysmic environmental changes, and sometimes that ...

The sixth extinction -- The mastodon's molars -- The original penguin -- The luck of the ammonites -- Welcome to the Anthropocene -- The sea around us -- Dropping acid -- The forest and the trees -- ...

Garbage in, garbage out. High protein, low fat. Cut the carbs and stay hydrated. It turns out it does matter what you eat, especially to crocodylians — crocodiles, alligators and gharials — a species ...
