Formation of Protocells

Today, we've realised that the very first life on Earth was indeed originated from abiotic surroundings. In fact, organic molecules have been successfully generated from abiotic elements by scientists

To understand how this creation of life from abiotic material occured, we have to consider a critical idea. Life originated from its abiotic surroundings. Thus, it is important for us to learn about the physical and chemical environments of the primitive Earth. The atmosphere of primitive Earth consisted of reactive, naturally availabe, molecules: Nitrogen (N2), water (H2O), methane (CH4), and ammonia (NH3), etc. These molecules what was needed to create life -- in fact, the percentage of hydrogen, oxygen, nitrogen, and carbon, together consists 99.5 % of all matters. In fact, the percentage of essential elements of life -- C, N, O, H, P, and S -- are quite similar from individuals to individuals.

Energy wise, the Earth had plenty from a variey of sources Radiation: from the cosmic and radioactive isotope decays UV light: there were no protective ozone layer and thus immense heat. Electrical discharge from the never ending lightning caused chemical reactions to occur very often and there was also another source of heat from


The cell developed Glycolosys, a organelle which produces energy, or, as it is better know ATP's(the fact that all living organisms today have some way of getting, or have producing ATP's show that they came from one "thing").

These amino acids, with the help of fatty acids, were able to form protocells.

This theory basically states there were many cells living on their own, but as more cells formed, they began to compete for recourses. They began to live in communities in order to get recourses more easily. Each cell had taken up a specific task and only did that task. Thus all these little cells began to change to enable it to do its task more easily.

These cell-like organisms were able to survive and reproduce in a very limited environment because of their simplicity. Over time, some of these protocells came together and shared their specialization in a symbiotic relationship.



Some common words found in the essay are:
Dr Fox, Nitrogen N2, Symbiotic Theory, , N2 H2, amino acids, fatty acids, formed organelles, chemical reactions, shared specialization symbiotic, limited environment simplicity, specialization symbiotic relationship, primitive earth, symbiotic relationship, organelles help, shared specialization, specialization symbiotic, simplicity protocells shared, acids building, environment simplicity protocells,
