Early eukaryotes, the lineage that later gave rise to animals, plants and fungi, may have depended on oxygen from the start.

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 ...

The companies that drilled these cores were largely unaware that within these mudstones were fossils of microscopic organisms ...

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 ...

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 ...

Researchers have uncovered a remarkable fossil site in a remote part of Canada's Northwest Territories, offering ...

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 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 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 ...
