About 65 million years ago, an asteroid crash supposedly wiped out all the dinosaurs on Earth. Now, scientists may soon finally solve the mystery behind this dino-killing crash.
It's no secret that ocean acidification caused by climate change is currently wreaking havoc on our oceans, but a new study shows that acidic oceans also triggered the greatest mass extinction ever on Earth.
Mountain gorillas are currently suffering from a serious inbreeding problem, and while scientists everywhere worry that this will lead them down the path to extinction, one new genetic study says that it might in fact be their salvation.
It turns out that toxic oceans are to blame, at least in part, for an ancient mass extinction event that occurred over 200 million years ago, new research says.
After researchers just announced that our oceans are riddled with eight million metric tons of plastic, a new comprehensive study found that nearly 700 marine species encounter and are threatened by such debris on a daily basis.
Australia's mammals are going extinct at an alarming rate, and voracious feral cats and foxes are to blame, according to new research.
American pikas, a pint-sized rabbit relative, are quickly losing their California mountain habitat to climate change, according to new research.
Overfishing, pollution, habitat loss and climate change are all factors that are threatening marine life, raising their risk of extinction by 20 to 25 percent, according to new research.
A lot of marine life may face extinction in the next 100 years as our industrialized world puts more and more pressures on ocean species, according to new research.
A cosmic impact may not have caused mammoth die-offs contrary to what one controversial theory says, according to a new study.
As we ring in 2015, we may also be greeting a new year during which several species, including the African elephant, polar bear and white rhino, may go extinct.
Despite popular belief, humans did not entirely hunt giant lemurs living on Madagascar into extinction thousands of years ago. Ancient DNA has revealed that their small population size is partly to blame, shedding light on what factors put today's modern lemurs at risk, a new study says.
Volcanoes may be to blame, at least in part, for the dinosaur die-off that occurred 66 million years ago, according to a new study, despite the widely held belief that a catastrophic meteor strike led to their extinction.
Humans have long been blamed for driving American mastodons to extinction, but new research indicates that these ancient behemoths suffered from freezing temperatures long before hunters arrived on the scene.
In an estimated six decades polar bears may not have any children at all. That's at least according to a recent study that estimates that by 2075, habitat reduction will have led to the utter elimination of adequate raising grounds for polar bear young, dooming the species.
