Geolo\u00adgical era: Archean<\/p>\n

Precurs\u00adors of cyanobac\u00adteria (formerly called blue-green algae) are the first cells whose traces can be detec\u00adted in old rocks. Thanks to their cell membrane they were able to regu\u00adlate the exchange of substances and energy with their environment.

The carbon diox\u00adide origin\u00adally present in the atmo\u00adsphere dissolves in the oceans and is used there to build up biomass. As a result, the atmo\u00adsphere now consists almost entirely of nitro\u00adgen. Oxygen is not yet present, and accord\u00adingly there is no ozone layer that protects against UV<\/span> rays. During this period the super\u00adcon\u00adtin\u00adent Ur might have formed.<\/p>\n","protected":false},"excerpt":{"rendered":"
