All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA—and it likely lived on Earth only 400 million years after its formation.

Life The surprising new idea behind what sparked life on Earth We may be starting to get a grasp on what kick-started life on Earth – and it could help us search for it on other planets By Chris ...

New research suggests “microlightning” exchanges among water droplets in Earth’s early atmosphere may have sparked the building blocks of life.

For decades, scientists believed that life on Earth took at least a billion years to get started. The prevailing idea was that the planet’s violent early history—especially a period of intense ...

"With the help of hydrothermal vents, nitrogen did not limit the spread of life on early Earth. Rather, life was able to flourish in both deep and shallow-water marine environments." ...

The origin of life on Earth is one of science’s biggest questions, and previous theories have suggested that lightning may have played a role. While previous studies say volcanic or atmospheric ...

The organization of life on Earth follows a simple, hidden rule known as “core-to-transition organization.” Hypothesized by biogeographers for centuries, a new study finally finds empirical evidence ...

Life on Earth won’t suddenly end—it will fizzle out with a slow, irreversible decline. But despite the long time span, researchers are urging the importance of preparation and adaptation for ...

While the origin of life on Earth is still up for debate, the Miller-Urey hypothesis suggests that a strike of lightning into ocean water mixed with inorganic gases may have triggered the ...

As astronomers study an exoplanet called K2-18b, conflicting research reveals how difficult it is to find evidence of life beyond Earth.

Researchers estimate that this will happen in the year 1,000,002,021, when Earth’s surface conditions become so extreme that life becomes impossible for even the most resistant organisms.
