dramatically. It was the time of the Cambrian Explosion, an eruption of life when Earth’s very first animals began appearing in the fossil record — the ancestors of all major animal groups ...

The Cambrian Explosion saw an incredible diversity of life emerge, including many major animal groups alive today. Among them were the chordates, to which vertebrates (animals with backbones ...

Use precise geolocation data and actively scan device characteristics for identification. This is done to store and access ...

Its end caused an alteration of climate that made possible the proliferation of animal life in Cambrian times There is considerable geological evidence for an extensive glaciation some 600 million ...

Some animals could likely tell the difference between light and dark, but they never knew whether that looming shadow was a friend or foe. Then, at the beginning of the Cambrian Period, life opened ...

All animal evolution for the last half billion years has come from tinkering with these Cambrian body plans. Then, between about 570 and 530 million years ago, another burst of diversification ...

Millions more species are believed to be still unknown to science. Arthropods were the most diverse animal group in the Cambrian period and the Ordovician period that followed. The 452-million ...

For instance, Darwin hoped we would discover transitional precursors to the animal forms that appear abruptly in the Cambrian strata. Since then we have found many ancient fossils – even exquisitely ...

This is an especially exciting find due to the age of the rocks – these fossils are found in rock layers which actually pre-date the oldest fossils of complex animals Dr Russell Garwood, School of ...

We seek to understand how animals evolved and shaped the biosphere and geosphere. We study the anatomy and genetic structure of fossils to understand the evolution of organisms. Members of Jakob ...
