The Cambrian "explosion" of multicellular animal life is one of the most significant evolutionary events in Earth's history. But what was it that jolted the Earth system enough to prompt the evolution ...
Decades of research shows that Earth was once entirely or almost entirely frozen. The episode is known as Snowball Earth, and ...

About 800 million years ago (mya), before the supercontinent Pangea formed, the Earth was more diverse than classical theory suggests. By reconstructing the tree of life from the evolutionary history ...
During the Sturtian glacial period during the Neoproterozoic Era, Earth underwent periods of global glaciation, which have been described as either "Snowball" and "Slushball" Earth scenarios. In ...
About 700 million years ago, the Earth experienced unusual episodes of global cooling that geologists refer to as 'Snowball Earth.' Geologists now suggest that those major climate changes can be ...
"This project grew from a Pardee keynote symposium ('Neoproterozoic geobiology : fossils, clocks, isotopes, and rocks') held at the 2003 Geological Society of America annual meeting in Seattle"--Pref.
For insight into what can happen when the Earth's carbon cycle is altered -- a cause and consequence of climate change -- scientists can look to an event that occurred some 720 million years ago. New ...
