Extinction

Jacob Haqq-Misra and Eric Wolf, researchers with the charity Blue Marble Space, argue in their recently published paper that Earth could stay green for nearly 1.9 billion years or more, depending on how the future plays out.

The marsupial may be a rare find in the wild these days, but they've nearly been wiped off the planet before. This study rewrites our understanding of the genetic history of koalas – and overturns the theories about what caused their ancient decline.

Texas-based company says its artificial egg supports the full development of bird embryos outside a biological eggshell, without requiring supplemental oxygen. The work is part of its plan to “de-extinct” birds, including the giant moa and dodo.

Dinosaurs may be long extinct, but 2025 made it clear that they’re anything but settled science. New fossils, reanalyses of famous specimens and increasingly sophisticated tools have helped us learn more about how they lived, moved, fed and evolved.

Like a plot mashup of Jurassic Park meets Game of Thrones, John Hammond meets Jon Snow, scientists at Colossal Biosciences claims to have pulled off the world's first de-extinction event. It's brought back the dire wolf.

The quest to resurrect the woolly mammoth has taken another step forward, with the creation of the Colossal Woolly Mouse. The lab-made rodents have been genetically altered to possess key physical traits of the extinct beasts – in fur and fat, at least.

Seeing a wombat in regional Australia is not a rare experience, but when ecologists captured this particular one emerging from a den and casually wandering past a motion-sensor camera in the middle of the night, there was serious cause for celebration.

A “bananageddon” might be on the horizon, and not for the first time. But new research could help save our favorite fruit.

How do we separate the movie myths of Tyrannosaurus rex from the actual animal? The Victoria the T-rex exhibition sets the record straight with recent discoveries about what T-rex looked and sounded like, how it sensed the world, and how it hunted.

We’re edging closer to seeing a live mammoth for the first time. Colossal Biosciences, a company dedicated to the controversial-but-unquestionably-cool goal of resurrecting extinct species, has made a breakthrough in creating elephant stem cells.

No-one has seen the Yellow-crested Helmetshrike for about 20 years. That changed when researchers embarked on a six-week expedition in the Democratic Republic of the Congo and captured the dramatic-looking yellow-topped bird in its first-known photo.

Most of us picture megalodon as a Jason-Statham-hunting monster that looked like a giant great white shark, but that probably wasn’t the case. A new study re-examines fossil evidence and suggests the creature was longer and more slender than thought.
