Diverse and full of sea life, the Earth's Devonian era—taking place more than 370 million years ago—saw the emergence of the first seed-bearing plants, which spread as large forests across the ...

If we did see a "local" supernova, we'd have plenty of time to develop the technology to protect the earth from its worst effects. Click to expand... We'd certainly have a lot of time, but I'm not ...

Violent supernovas may have caused two of Earth’s largest mass extinctions that have never been completely explained, according to a theory put forward in new research.During the final stages of a ...

Paleontologists recently discovered a new extinct coelacanth species that highlights the role that Earth’s plate tectonics plays in evolution. Also called Latimeria, coelacanths are a deep-sea fish ...

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 ...

Our planet’s first known mass extinction happened about 440 million years ago. Species diversity on Earth had been increasing over a period of roughly 30 million years, but that would come to a halt ...

In times of environmental upheaval, how do communities of organisms respond? When entire species are wiped out, do surviving species move in and take over, or do new species immigrate to fill the gaps ...
