3.8 Billion Years ago, life begain

This would have been a very simple version of a Cell

This Cell would have been able to take in matter, release energy by breaking down compounds

This Cell would have been able to use the energy to assemble new compounds

This Cell would have been able to grow in size and then divide into two new cells

This Cell would have had a membrane made of Lipid (Fat)

This Cell would have contained mostly water, warmed by the geothermal vent that it was next to

This Cell would have contained amino acids, that assembled into the first proteins

This Cell would have had some type of Nucleic Acid - probably RNA

This RNA would have fulled some of the functions that are now done by proteins

This Cell would use energy from the Vent to Create CHO compounds - such as sugar

This Cell would then break down these CHO compounds - such as sugar - releasing the energy where and when it is needed within the cell

Life Moves into the Light

Some of the Thermal Vents supporting life would have risen to the surface of the ocean

Here life mixes with the Light from the sun

This life is still taking in Carbon Dioxide that is dissolved in the sea water and then using Hydrogen Sulfide it undergoes Chemosynthesis - which is to Chemically synthesize a molecule that links together Carbon, Oxygen and Hydrogen, a Carbohydrate - Glucose - from which all other Biological molecules can be created.

In other words, these ancient cells start to use sunlight to synthesize Glucose from Carbon dioxide and Water

These cells start to Photosynthesize
