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 ...

Mineral sink may have limited ocean phosphorus and delayed oxygen rise
A hidden mineral trap in ancient ocean sediments may have starved early marine life of phosphorus, the nutrient most critical ...
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 ...
Gigantic dragonfly-like insects – the “griffinflies” – ruled the skies around 300 million years ago, but they have long been ...
