Supporting and Protective Skeletons

560 million years
or 137 meters to today

Geolo­gi­cal era: Neopro­ter­o­zoic / Edia­ca­rian

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.
