Oxygen played a key role in the evolution of complex organisms, according to new research published in BMC Evolutionary Biology. The study shows that the complexity of life forms increased earlier ...

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

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 original version of this story appeared in Quanta Magazine. Far from being solo operators, most single-celled microbes are in complex relationships. In the ocean, the soil, and your gut, they ...

The research led by the University of Bristol was published in the scientific journal Nature 3 December, the research indicates that complex organisms evolved long before there were substantial levels ...

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 ...

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 ...

The evolution of complex life is strictly dependent on mitochondria, the tiny power stations found in all complex cells, according to a new study by Dr Nick Lane, from UCL (University College London), ...

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 ...

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 ...
