The earliest animals may have evolved hundreds of millions of years before their first unmistakable fossils appear in the fossil record, according to a new study led by the University of Oxford. The findings, published in Science Advances, suggest animals may have originated deep in the Neoproterozoic Era, even before some of the most extreme ice ages in Earth's history.

Ancient sea levels reveal when the Earth's poles went wandering
Earth's poles do not always stay in the same place. For example, a region once near the North Pole can end up near the equator, and an area near the equator can shift up toward the pole. This is known as true polar wander (TPW), and it's when Earth's crust and mantle shift togeth

How much are the world's oceans warming? New method reveals double-digit percentage gaps from climate models
The world's oceans behave like a thermometer: As the water warms, it expands and sea levels rise. Geodesy researchers at the University of Bonn are able to measure this and determine how much the oceans are warming. For individual ocean basins, their method has revealed significa
