Researchers investigating the origin of complex life on Earth might have just made a major breakthrough. The origin of ...

Complex cells are thought to be the result of a union between two ancient microorganisms, but scientists have long been ...

A team led by researchers at the University of Texas at Austin has produced what may be the strongest evidence yet that the ancient ancestors of all complex life on Earth already had the genes to use ...

The timeline of terrestrial evolution holds surprises. While scientists thought complex life required oxygen, a recent discovery shows it began forming in oceans deprived of this element, nearly a ...

About 700 million years ago, enormous glaciers flowed across the Earth's surface in powerful frozen rivers like "giant ice bulldozers" that pulverized our planet's crust and may have contributed to ...

Around 700 million years ago, Earth was a frozen, white sphere, its rocky surface buried kilometers under ice. Despite the barren landscape, the evolution of complex life in the oceans was about to ...

The team has proposed a new evidence-based scenario for the emergence of complex life they have called ‘CALM’ - Complex Archaeon, Late Mitochondrion. Complex life began to develop earlier, and over a ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. A study led by researchers from the University of Sydney and the ...

Scientists suggest finding extraterrestial intelligence is more likely than thought, arguing that complex life is not a cosmic fluke. NASA Scientists have adhered to the “hard steps” model 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 ...

The evolution of intelligent life around red dwarf stars is likely to be an uphill slog, due to the demands needed to jumpstart oxygenic photosynthesis. Given that red M-dwarf stars are by far the ...

A biochemist, building on the pillars of evolutionary theory and drawing on cutting-edge research into the link between energy and genes, argues that the evolution of multicellular life was the result ...
