Timeline of Evolution of Life

  • Creation 4.6 Million yrs ago Anoxic

  • Organic Molecules 4.5 Bllion yrs ago Anoxic

    An organic compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon. For historical reasons discussed below, a few types of carbon-containing compounds such as carbides, carbonates, simple oxides of carbon and cyanides, as well as the allotropes of carbon such as diamond and graphite, are considered inorganic.
  • Membrane 4-3.5 Billion yrs ago Anoxic

    The cell membrane is a biological membrane that separates the interior of all cells from the outside environment.[1] The cell membrane is selectively-permeable to ions and organic molecules and controls the movement of substances in and out of cells.
  • Procaryotic Cells- Heterotrophic 3.8 Billion yrs ago Anoxic

  • Procaryotic cells-Autotrophic 3 Billion yrs ago Anoxic/oxic

  • Eucaryotic cells 2 Billion yrs ago Oxic

    A eukaryote is an organism whose cells contain complex structures enclosed within membranes. The defining membrane-bound structure that sets eukaryotic cells apart from prokaryotic cells is the nucleus, or nuclear envelope, within which the genetic material is carried.
  • Colonial Organisms 600 Millions yrs ago Oxic

    A colony of single-celled organisms is a colonial organism. It's likely that early colonial organisms were the first evolutionary step from single celled life to multicellular species. Some colonial organisms closely resemble multicellular organisms; you can tell the difference by separating single cells from the rest of the organism. If the cells always die, the source was a multicellular organism.
  • Multicellular organisms 550 Million yrs ago Oxic

    Multicellular organisms are organisms that consist of more than one cell, in contrast to single-celled organisms. Most life that can be seen with the naked eye is multicellular, as are all animals (except for specialized organisms such as Myxozoa) and land plants.
