If all the world's a stage and all the species merely players, then their exits and entrances can be found in the rock record ...

Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but ...

Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but a new analysis extends the chart of life to nearly 2 billion years ago. The ...

Advanced tools and expanded fossil datasets have painted a clearer picture of the eukaryotic diversity of the Proterozoic eon, which has been hard to quantify. The findings show that Earth's severe ...

Virginia Tech’s study traces early eukaryotic evolution, highlighting life’s diversification since 2 billion years ago.

Ancient species may have evolved more slowly and lasted longer, but the pace of evolution picked up after global ice ages, ...

Over the 1.5 billion years of the Proterozoic Eon, a crucial innovation in terrestrial life unfolded — one without which we would not exist today ...

During the Proterozoic era, oxygen produced by photosynthesizing bacteria collects in the oceans and then in the atmosphere. Iron present in exposed rocks reacts with this oxygen, and rust colors ...

However, our understanding of global fossil diversity of Proterozoic life, particularly for eukaryotes, has been limited by ...
