We have only one example of biology forming in the universe – life on Earth. But what if life can form in other ways? How do you look for alien life when you don’t know what alien life might look like ...

Life on Earth began in a way that still boggles the mind. Around 4.5 billion years ago, a chemical process called abiogenesis occurred, where life emerged from non-life. Imagine a hot, watery mix of ...

The story of Charles Darwin’s life. His theory of evolution changed the way we understood our place in the world.

Life on Earth began in a way that still boggles the mind. Around 4.5 billion years ago, a chemical process called abiogenesis occurred, where life emerged from non-life. Imagine a hot, watery mix of ...

For decades, many scientists have relied on the "hard steps" model to suggest that intelligent life is rare — the improbable result of a series of unlikely evolutionary leaps. But new research by ...

Fossils don't always come in large, dinosaur-sized packages. Microfossils refer to a type of fossil that is so small, it can only be perceived with a microscope. These microfossils can help us ...

The emergence of human life may not have been as improbable as scientists once thought, a new model suggests. The finding increases the likelihood of intelligent life elsewhere in the universe, the ...

Humanity may not be extraordinary but rather the natural evolutionary outcome for our planet and likely others, according to a new model for how intelligent life developed on Earth. The model, which ...

A study presents a striking example of cooperative organization among cells as a potential force in the evolution of multicellular life. The study is based on the fluid dynamics of cooperative feeding ...

Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but a new analysis extends the chart of life to nearly 2 billion years ago. The ...
