Stanford scientists have found that chronically low levels of oxygen throughout the oceans hampered the recovery of life after the Permian-Triassic extinction, the most catastrophic die-off in our planet's history. Also known ...
You know that greenhouse gases are changing the climate. You probably know drinking water is becoming increasingly scarce, and that we're living through a mass extinction.
Mammals with large brains tend to be smarter but they also face a greater chance today of going extinct, according to a study published Wednesday.
European bison imported from Poland now roam Denmark's Baltic island of Bornholm in places where the animals haven't lived for thousands of years. Meanwhile, in a far corner of Siberia, scientists are attempting to reconstruct ...
A Yale-led study urges scientists to move their focus from species extinction to species rarity in order to recognize, and avoid, a mass extinction in the modern world.
Periods of high extinction on Earth, rather than evolutionary adaptations, may have been a key driver in the diversification of amniotes (today's dominant land vertebrates, including reptiles, birds, and mammals), according ...
New research may draw a 'curtain of fire' on dinosaur extinction theory
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 Professor John Long.
A British-led project called "Frozen Ark" is preserving the DNA of endangered species before they disappear as the Earth undergoes what scientists are calling the sixth mass extinction.
When times are good, it pays to be the big fish in the sea; in the aftermath of disaster, however, smaller is better.
