The event that killed the dinosaurs 66 million years ago might be the most famous mass extinction ever, but it's not the only one in Earth’s history, nor is it the worst... not by a long shot.

The Great Dying hit life hard, but the species that survived took over the planet and diversified into many interesting forms, including the dinosaurs!

Paul Andersen details the evolutionary processes of speciation and extinction. Stickleback evolution in Lake Loberg is used as example of rapid speciation. Adaptive radiation is illustrated using the Hawaiian honeycreeper. A brief...

It's amazing to think about the animals we've managed to save from the brink of extinction. Thanks to conservation efforts, species like the California condor, black-footed ferret, and the Arabian...

Brit looks back on our twelfth month on Nature League, when we explored the theme of extinction.

This week on Nature League, Adrian asks Brit what the next dominant species would be if humans went extinct.

This week on Nature League, Brit Garner explores the past and present extinctions of life on Earth.

This week on Nature League, Brit Garner visits Makoshika State Park to see the Cretaceous-Paleogene boundary where the dinosaurs went extinct. Special thanks to Dr. Dan Lawver and Chris Torres!

This week on Nature League, Brit Garner explores extinction threats to life on Earth by breaking down a recent scientific journal article about the endangered state of the world’s insects.

This video explores the concept of the Anthropocene epoch, also known as the age of humans. The video discusses the negative impacts of human activity on the planet, including climate change, mass extinction, and environmental injustice....

Sixty-six million years ago, an asteroid slammed into the Earth's atmosphere, traveling 45,000 miles per hour. The asteroid ripped a hole 18 miles deep in the Earth's crust, triggering devastating winds, seismic waves, and tsunamis. For...
