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

Scientists say they just cracked a huge conundrum behind complex life
A team led by researchers at the University of Texas at Austin has produced what may be the strongest evidence yet that the ...
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 ...
Most days you move through the world without thinking about the invisible creatures that surround you. Yet one of them, a tiny marine organism called Solarion arienae, is quietly reshaping what you ...
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 ...
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 ...
A giant virus discovered in Japan is adding fuel to the provocative idea that viruses helped create complex life. Named ushikuvirus, it infects amoebae and shows unique traits that connect different ...
Complex life began to develop earlier, and over a longer span of time, than previously believed, a new study has revealed. The research sheds new light on the conditions needed for early organisms to ...
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 ...
