The first fossils of clusters of interconnected cells date from this period. By connecting, they lay the foundation for the division of labour among cells and the development of more complex living beings.
Structural proteins give form and support to rapidly developing organisms. The incorporation of calcium carbonate into the skeletons creates firm armour which not only supports the organisms but also provides protection against injury. This allows larger life forms to develop. Many basic blueprints of living beings were created and still exist today.
The displacement of land masses near the poles interrupts the cycle of alternating icing and overheating of the earth. The CO2 content of the atmosphere stabilizes and with it the temperature.
