Rare meteorites challenge our understanding of the solar system

Researchers have discovered minerals from 43 meteorites that landed on Earth 470 million years ago. More than half of the mineral grains are from...

Simple fats, amino acids to explain how life began

Life is a process that originated 3.5 billion years ago. It emerged when the basic components of the cells that we know today, in...

First humans arrived in North America a lot earlier than believed

The timing of the first entry of humans into North America across the Bering Strait has now been set back 10,000 years. This has been...

Study of 3.5 billion years of Earth’s history

For three billion years or more, the evolution of the first animal life on Earth was ready to happen, practically waiting in the wings....

Ancient rocks hold evidence for life before oxygen

Somewhere between Earth's creation and where we are today, scientists have demonstrated that some early life forms existed just fine without any oxygen. While researchers...

Asteroid impacts could create niches for early life, suggests Chicxulub crater...

Scientists studying the Chicxulub crater have shown how large asteroid impacts deform rocks in a way that may produce habitats for early life. Around 65...

Study finds Earth’s soils hosted life early

Way before trees or lichens evolved, soils on Earth were alive, as revealed by a close examination of microfossils in the desert of northwestern...

‘False’ biosignatures may complicate search for ancient life on Earth, other...

Self-assembling carbon microstructures created in a lab by University of Colorado Boulder researchers could provide new clues -- and new cautions -- in efforts...

Life took hold on land 300 million years earlier than thought

Life took hold on land at least as early as 3.2 billion years ago, suggests a study by scientists from Berlin, Potsdam and Jena...

Did Meteorites Bring Life’s Phosphorus to Earth?

Meteorites that crashed onto Earth billions of years ago may have provided the phosphorous essential to the biological systems of terrestrial life. The meteorites...

Life in ancient oceans enabled by erosion from land

As scientists continue finding evidence for life in the ocean more than 3 billion years ago, those ancient fossils pose a paradox. Organisms, including...

Earthquakes, ‘Mars-quakes,’ and the possibility of life

A new study shows that rocks formed by the grinding together of other rocks during earthquakes are rich in trapped hydrogen -- a finding...

‘False’ biosignatures may complicate search for ancient life on Earth, other...

Self-assembling carbon microstructures created in a lab by University of Colorado Boulder researchers could provide new clues -- and new cautions -- in efforts...

New discovery shatters previous beliefs about Earth’s origin

A new study led by Western University's all-star cosmochemist Audrey Bouvier proves that the Earth and other planetary objects formed in the early years...

The Origin of Life: RNA World Deep Beneath the Surface

Where did life begin—in a shallow lagoon, or in a vent of superheated water spewing from the ocean floor? If we knew, we might...

Arctic gives clues on worst mass extinction of life

Extreme global warming 252 million years ago caused a severe mass extinction of life on Earth. It took life up to 9 million years...

Earth interacted with supernova remnants for 1 million years

Physicists from the Technical University of Munich (TUM) have succeeded in detecting a time-resolved supernova signal in Earth's microfossil record. As the group of...

How China is rewriting the book on human origins

On the outskirts of Beijing, a small limestone mountain named Dragon Bone Hill rises above the surrounding sprawl. Along the northern side, a path...

Rock salt holds the key to a paradigm shift

A team of international scientists from China, France, Scotland, United States and led by Canadian Professors Nigel Blamey and Uwe Brand of Brock University...
