Ancient ocean grains show Earth’s carbon levels were far lower than expected during key evolutionary eras. The results challenge old theories of life’s rise and hint at patterns that could shape our ...

A missing piece of Earth's evolutionary timeline may have been found. Using computational modeling, a team of scientists explored how working backwards from modern biochemistry could help map out how ...

Welcome to the early solar system. Just after the planets formed more than 4.5 billion years ago, our cosmic neighborhood was a chaotic place. Waves of comets, asteroids and even proto-planets ...

New research shows fungi diversified nearly a billion years ago, shaping soils and ecosystems long before plants colonized ...

What if you could travel through time and watch history unfold, one era at a time? With TimeMap.org, you can do just that—no time machine required. This interactive history map lets you dive into the ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

According to a recent study, events geologists use to distinguish transitions between geological chapters in Earth's story follow a hidden hierarchical pattern, one that could shed light on both past ...

Our species likes it cold. Homo sapiens evolved in — and still inhabits — one of Earth’s rare and fragile ice ages, periods distinguished not by an abundance of saber-toothed cats and woolly mammoths ...
