Something even worse might be happening today.
There’s a lot to be grateful for the first mammalian ancestors who evolved side-to-side chewing.
Welcome to the planet’s sixth major extinction — take a seat.
For the first time in history, a bee in continental US has been listed as endangered.
Scientists are trying to de-extinct ancient cows called aurochs.
The cheetahs can’t outrun humanity.
A new report published by the IUCN shows that the emblematic giraffe is facing a threatening decline.
Large marine species are favorably lost which could disrupt marine ecosystems for millions of years.
Humpback whales have made an epic return.
While the situation of pandas is improving, the same can’t be said about great apes.
In between rising temperatures and human hunters, mammoths and sabretooth tigers stood no chance.
Helicoprion is an extinct genus of shark-like, cartilaginous fish that lived from the early Permian (~290 m.y. ago) all through to the massive Permian-Triassic extinction episode (roughly 250 m.y. ago.)
For the first time in over one hundred years worldwide tiger numbers have increased, but there are still only 3,900 specimens in the wild.
Drastically reducing body size and, maybe most importantly, lifespan may have been the most important course of action evolution undertook to preserve some species, paleontologists argue.
Europe is likely to lose all its ash trees, the largest-ever survey of the species warns. Plagued by both a fungal disease known as ash-dieback and an invasive species of beetle, the emerald ash borer, the tree might be wiped clean off of the continent.
We judge our planet’s biological past by using geological evidence – fossils. Fossils are the preserved remains or traces of animals, plants, and other organisms from the remote past.
Some 360 million years ago, the oceans were teeming with big fish, some as big as a school bus. Then something terrible happened, the causes of which still escape scientists today: the Hangenberg Event. This was the last peak in a streak of mass extinctions known as the Late Devonian extinction which exterminated 97% of all marine vertebrate species. In the aftermath, it paid to be small a new study suggests. The researchers at University of Pennsylvania found that small fish dominated the ecological niches for nearly 40 million years. This tremendous rebound time is relevant today when overfishing is threatening countless large fish species. Once these disappear, it might be a very long time before we get tuna-sized fish back on our plates.
When we talk about extinction, we tend to think of it in the past-tense, or as something that just kind of happens, far removed from the activities of humankind. So let’s put things in perspective, just so we fully understand the scope of extinction.
