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 ...
Scientific consensus is that high oxygen levels allowed these humongous fliers to exist, but a new study throws that idea ...
More than 2 billion years ago, long before Earth's atmosphere contained oxygen, one hardy group of microbes may have already evolved to live with the gas, setting the stage for the rise of complex ...
Breathe easy. It appears our microbial ancestors used oxygen, too. In December 2025, Brett Baker led a research cruise to collect microbial genomes off the coast of Uruguay. In this photo, Tyler Smith ...
The evolution of complex life forms may have gotten a jump start billions of years ago, when geologic events operating over millions of years caused large quantities of phosphorus to wash into the ...
This perspective article, led by RASEI Fellow Tanja Cuk, brings together researchers at six research institutions from across the United States, to describe how advances in spectroscopy and theory can ...
