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 ...

Environmental evidence of the very first experiments in the evolution of complex life on Earth, has been uncovered by an international team of scientists. Until now, scientists broadly accepted ...

Life’s leap from single-celled to multicellular organisms marks a pivotal moment in evolutionary history. This transformation laid the foundation for the complex life forms we see today. By studying ...

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 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 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 ...

As the sun expands over the coming billions of years, Earth will become inhospitable to any life more complex than a microbe – but that might take longer than we thought ...

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 ...

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?

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 ...
