Life on Earth may have first emerged from complex chemical reactions in two different ways near a deep-sea hot spring, a new ...

Life on Earth is thought to have emerged from the primordial ooze some four billion years ago. Now a provocative new study ...

For as long as humans have looked toward the stars, one question has remained unanswered: how did life begin? Scientists have ...

How did life begin on Earth? While scientists have theories, they don't yet fully understand the precise chemical steps that led to biology, or when the first primitive life forms appeared. But what ...

University of Alberta geochemists have discovered a missing piece to one of the great mysteries of science—the origin of life on Earth. That fateful spark is believed to have occurred on the ocean's ...

Here’s what you’ll learn when you read this story: Single-celled microbes are believed to be Earth’s earliest life forms, but their soft bodies left almost no fossil evidence behind. Recent research ...

Asteroid impacts may have helped kick-start life on Earth by creating hot, chemical-rich environments ideal for early biology. These impact-generated hydrothermal systems could have lasted thousands ...

Sugars are crucial components of RNA and DNA, the basis of all known organisms alive today. In a new study, the sugar erythrulose was detected in a gas- and dust-filled cloud near the center of our Mi ...

Tiny fossils from Earth’s deep past may reveal when cellular complexity first emerged. Their survival could reshape both ...

Researchers propose that tiny mineral nanoparticles may have been the hidden engines that transformed Earth’s early chemistry into the first building blocks of life. By acting as natural catalysts and ...

the Earth you walk on today might not be the same planet that was born 4.5 billion years ago. Many scientists believe that in its infancy, Earth collided with another world the size of Mars, and that ...
