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
- Prokaryotes have no membrane-bound organelles
- Prokaryotes have a single circular chromosome that may be 500 times the length of the cell.
- Heterotrophic prokaryotes feed on organic matter by secreting enzymes and absorbing the digested material. Most heterotrophic prokaryotes are aerobic. The three types of heterotrophic procarytic cells are Parasites, Mutualistic, and Saprotrophic

Procaryotic cells-Autotrophic 3 Billion yrs ago Anoxic/oxic
- There are two kinds of Autotrophic procaryotes photosynthetic and chemosynthetic (make organic food using energy from inorganic compounds Prokaryotes reproduce by binary fission.

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. -
