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 ...

Paleontologists who study earth’s ancient fossil record might not seem to be the obvious choice when asking about the prevalence of intelligent life in the cosmos. But paleontology, the study of ...

Yet modern biology has revealed that cells are preternaturally sophisticated assemblages — literally automated, miniaturized factories. How could the evidence have been overwhelming but now orthodoxy ...

For decades, scientists assumed that life on Earth emerged through a chain of highly improbable flukes. But a new theory suggests it may have instead arrived just in time. When you purchase through ...

Chris Impey receives funding from the National Science Foundation and the Howard Hughes Medical Institute. We have only one example of biology forming in the universe – life on Earth. But what if life ...

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 ...

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?

Giant DNA viruses that infect eukaryotic cells are thought to have played a role in the evolution of life, according to the ...

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 ...
