700,000-year-old squirrel poop helps scientist recreate an ancient world

A trove of prehistoric squirrel poop packed with 700,000-year-old environmental DNA is helping scientists reconstruct a lost Yukon ecosystem teeming with plants, insects, microbes, and large mammals. Image: Scott Cocker

Oxfordshire dinosaur highway 'one of the longest in the world'

A dinosaur trackway containing around 200 footprints, discovered by a worker at Dewars Farm Quarry in Oxfordshire four years ago, has been identified as one of the longest of its kind in the world. Image credit: Oxford University Museum of Natural History

New Scientist recommends a brilliant take on the evolution of birds

Paleontologist Steve Brusatte's new book The Story of Birds traces how feathered dinosaurs survived an asteroid strike and evolved into the birds that fill today's skies. Image credit: JA CHIRINOS/SCIENCE PHOTO LIBRARY

Earth’s earliest animals may have thrived too easily to evolve

Fossils from some of Earth’s earliest animals suggest cloning dominated Ediacaran seas, slowing evolution until environmental stress triggered a burst of biodiversity. Image credit: C.G. Kenchington.

Imagine if dinosaurs hadn't gone extinct. Here's what scientists think may have happened next

If the asteroid had missed Earth 66 million years ago, dinosaurs may have continued evolving and dominating the planet to this day. Image credit: Colin Anderson Productions

Fossil discovery in Patagonia reveals new species of horned turtle

Paleontologists have identified a new species of meiolaniform turtle from northern Patagonia, Argentina, that lived during the Maastrichtian age, just before the asteroid-triggered mass extinction that wiped out all non-avian dinosaurs. Image credit: Nawel Vazquez

120,000-year-old European fallow deer—tracing the loss of genetic diversity

Some pterosaurs may have boasted bold iridescence

A new analysis of a 120-million-year-old fossil suggests at least one pterosaur species shimmered in iridescent greens and magentas. Image credit: Zhao Chuang

Ancient oceans began losing oxygen millions of years before the end-Triassic mass extinction

Chemical traces preserved in ancient rocks indicate that marine environments were deteriorating long before the catastrophe that wiped out vast numbers of species at the end of the Triassic period, around 201 million years ago. Image credit: Peter Sawyer

Epigenetic changes can be inherited without changing DNA in animals

New evidence suggests animals can pass down inherited traits through epigenetic changes rather than DNA mutations. Image credit: Karmannye Chaudhary

Ancient cave lion genomes reveal a distinct lineage

A new study on multiple genomes from the extinct cave lion has discovered that it represented a highly distinct evolutionary lineage, which separated from modern lions more than a million years ago. Image credit: Love Dalén.

How Jupiter may have redirected life's ingredients toward Earth 4.5 billion years ago

Extraordinary fossils solve a 500-million-year mystery: Bryozoans were there at the dawn of animal life

Fossil evidence from approximately 520-million-year-old rocks in China finally places bryozoans where they belong, at the heart of the Cambrian explosion. Image credit: Baopeng Song

Scientists find signs of active life in Ötzi the Iceman

Even after 5,300 years in the ice, Ötzi the Iceman may still host active microbes, with some cold-loving species apparently surviving—and possibly reproducing—on his mummified body. image credit: South Tyrol Museum of Archaeology/Eurac Research/Marion Lafogler
