ARCHEAN ERA

Lasting more than twice as long as the Phanerozoic eon, the Archean was a time when diverse microbial life flourished in the primordial oceans, and the continental shields developed from volcanic activity. The reducing (anaerobic) atmosphere enabled archea (anaerobic microbes) to develop, and plate tectonics followed a regime of continental drift different to that of the Proterozoic and later. During this era, one type of organism, the Cyanobacteria (blue-green algae) produced oxygen as a metabolic by-product; the eventual build-up of this highly reactive gas was to eventually prove fatal to many life-forms, and converted the atmosphere from.

  1. Hi,

    I'm just browsing sites for the kids of Haiti.

    I'm at this site for a non-profit organization that spends their time to
    creating an oppurunity for the kids in haiti. If anyone wants to give money then this is the place:

    [url=http://universallearningcentre.org]Donate to Haiti[/url] or Help Haiti

    They give children in Haiti a positive outlook through education.

    Yes, they're legit.

    Any help would be great
