It’s always unfortunate when a species goes extinct. This tragedy usually happens over a prolonged period, but certain events ...

A group of scientists and NASA got together and with the help of supercomputers came up with a date for total and complete ...

Specifically, the findings support the hypothesis that supernovae could have triggered two of the so-called "big five" mass ...

Nearly all the ... the two events occurred within 100,000 years of each other. Renne doubts that's a coincidence. But the Siberian Traps volcanoes didn't cause the extinction by swamping the ...

But occasionally, extinction rates have surged far beyond usual levels, driving mass extinction events that have reshaped the trajectory of life. After a year teaching an algorithm to differentiate ...

Scientists don't call it the "Great Dying" for nothing. About 252 million years ago, upward of 80% of all marine species ...

which occurred 445 million years ago and was the first of the big five mass extinction events in our planet's history. 75% of all species, particularly in the types of fish found in ancient seas ...

The fossil record—an incomplete archive of biodiversity, as not all organisms fossilize—has produced various estimates of background extinction rates, that is, the usual rate of species turnover in ...

However, the Cretaceous–Paleogene extinction event was not the worst loss of life ... about 80 to 90 percent of all species on Earth were wiped out and the biosphere of the planet was completely ...

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 say these super-powerful blasts ...

To investigate whether supernovae align with extinction events ... Earth may have been triggered by cosmic events challenges ...

Scientists predict that more than 1 million species are on track for extinction in the coming decades. But there’s still time to halt this crisis — and we need your help. Check out all the Center’s ...
