Scientists have uncovered new clues about some of Earth’s earliest fish, shedding light on the ancient origins of vertebrates ...

For the last few years, I’ve carried around a primitive mobile device called the Light Phone II, otherwise known as a “dumbphone.” It’s a tiny hunk of gray plastic approximately the size of a credit ...

Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple microorganism took the first steps toward complex life. From this ancestor emerged ...

Around 2.3 billion years ago, the Great Oxygenation Event (GOE) marked a major turning point in Earth’s history. The increase ...

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 ...

Beneath its icy crust, Europa may conceal a salty ocean larger than all of Earth’s oceans combined. Shielded by miles of ice, warmed from within, and rich in active chemistry, this moon of Jupiter ...

These compounds are similar to fatty acids, which on Earth are most often produced by living things. A new study concluded that non-biological processes, like meteorites crashing into Mars, alone ...
