With this time period we often suggest a cell-like constitution containing the minimum and enough variety of elements to be outlined as alive, or at the very least in a position to exhibiting a number of the basic services of a residing telephone.

Certain atoms contained in this soup, such as C, H, O, N, P, S, would have been at origin of all organic molecules on Earth today. Under the impact of various sources of energy, such as heat, lightning and ultraviolet solar rays, mineral matter formed the first organic molecules: some protein-based amino acids, some fatty acids based on lipids, nucleotides, etc. ) facilitated the catalysis of the reactions by which organic molecules were formed. There is a consensus that the scenario of the origin of life took place in water or at the interface of an aqueous phase and an organized chemical substrate.

Mutations spontaneously create new alleles. The range of genetic diversity observable at any given time depends, firstly, on the rate at which mutations appear, and secondly, on the possibilities for the mutated forms to develop and compete successfully with other forms of life. 2 ORIGINS AND DYNAMICS 45 . ); . during the replication and/or recombination of the DNA, localized secondary structures may form on either strand and interfere with the process of duplication and pairing, causing repetitions, deletions, etc.
