Evolution: Biogenesis and Development in the Precambrian

  • 3 BCE

    Beginning of Rock and Land

    Beginning of Rock and Land
    The Archean era began with the formation of rocks and plates across Earth from the ongoing crashing of rocks and objects on the globe.
  • 2 BCE

    Formation of Earth's Layers

    Formation of Earth's Layers
    With the colliding of rocks and chemicals forming, layers of the Earth started to form with mostly rock on the crust and the mantle's composed of iron and other metals.
  • 2 BCE

    Tectonic Plate Formation

    Tectonic Plate Formation
    With the combination of many chemicals and physical formations across the globe, many of them did not mend together resulting in the denser properties falling beneath or subducting underneath the less dense properties. This formed many of the current land structures today, or continents.
  • 2 BCE

    Living Formations

    Living Formations
    Life began to thrive from chemical compounds, carbon, and microbial mats.
  • 2 BCE

    Breaking Up Of Supercontinent

    Breaking Up Of Supercontinent
    The supercontinent of Vaalbara, formed by the collection of then rock, separated due to tectonic activity from volcanoes
  • 2 BCE

    Kenorland

    Kenorland
    Many other land masses began to form, such as Kenorland, forming the base of many modern day continents and countries across the globe.
  • 2 BCE

    Ocean Formation

    Ocean Formation
    Oceans were formed due to the condensation of water in the atmosphere from the gas of volcanic activity. Oceans during this time also had a green hue to them due to ferrous hydroxy salts.
  • 2 BCE

    Formation of Organisms

    Formation of Organisms
    Formation of tiny, single celled organisms that did not require oxygen.
  • 2 BCE

    Photosynthesis Emergence

    Photosynthesis Emergence
    Many plants began to use the modern form of photosynthesis to began growing. The sun became a vital part of life due the late Archean.
  • 2 BCE

    Banded Iron Formation

    Banded Iron Formation
    Formation of sedimentary rock from iron, chert, and cyanobacteria known to have been created in the ocean during photosynthesis.
