Among biologists, few questions have been debated as fiercely as the origin of life. How did self-sustaining organisms, ...

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

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 ...

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 ...

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 ...

A four-carbon sugar discovered 26,000 light-years away may explain how DNA's backbone arrived on Earth.

Meteor impacts may have helped spark life on Earth, creating hot, chemical-rich environments where the first living cells could take shape, according to research integrated by a recent Rutgers ...

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 ...

A drawing of an orange, cloud-covered planet against a black background During the Archean Eon, 4-2.5 billion years ago, Earth likely looked very different than it does today. Its hazy skies may have ...
