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 ...

Life on Earth began in a way that still boggles the mind. Around 4.5 billion years ago, a chemical process called abiogenesis occurred, where life emerged from non-life. Imagine a hot, watery mix of ...

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 ...

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 ...

Evidence was found in marine sedimentary rocks near Gabon in Central Africa. A team of international researchers has challenged the long-held belief that complex life forms first emerged on Earth 635 ...

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 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), ...

Life on Earth may exist thanks to a brief faltering in our planet's protective magnetic field shell, scientists have found. A bizarre drop in the strength of the magnetic field has been found to have ...

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 ...

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 ...
