To date, Earth is the only planet we know of that has continents. Exactly how they formed and evolved is unclear, but we do know – because the edges of continents thousands of miles apart match up – that, at one...

Just over half a billion years ago, Earth was rocked by a global mass extinction event, a dramatic interruption of the Cambrian explosion of life on Earth. It wiped out an estimated 50% to over 90% of animal species, particularly...

It’s difficult for most people to grasp the immensity of time as it’s viewed by archeologists, much less as it’s viewed by geologist or cosmologists. One way often used by those scientists to model time in terms that others can...

During the last ice age, humans ventured into two vast and completely unknown continents: North and South America. For nearly a century, researchers thought they knew how this wild journey occurred: The first people to cross the Bering Land Bridge,...

Analysis of how long erratics have been exposed on ice-free ground in the hypothesized “Late Pleistocene ice-free corridor migration route” suggests that route was not fully open until about 13,800 years ago, and the ice sheets “may have been 1,500...
