The Origin of Life and Evolution

It is considered that the most primitive cells were formed when:

• Some protocells were able to move, reproduce and interact with others.

• Some protocells were able to carry out cellular respiration and reproduce.

• Some protocells were able to exchange matter and energy with the exterior, adapting to environmental changes and producing replicas of themselves.

• Some protocells were able to produce different replicas of themselves and breathe.

According to endosymbiotic theory, the nucleus of eukaryotic cells:

• Came about due to the DNA coiling and the edges hardening for protection.

• Was formed by folding of the membrane of a prokaryotic cell.

• Was formed by a different mechanism to the above three.

• Was another aerobic prokaryotic cell which was swallowed and lived in symbiosis with the first.
