The continuity of the species has priority over the individual. This genetic condition explains the strange behaviour of many living beings that go to the extreme of committing suicide in order to feed newly- born offspring.  

1.b) Improve the efficacy.  

When a capacity or quality is used intensely, the quality is considerably improved. It would seem logical that the programs or functions were incorporated at least in part into the genetic information to be sent.

The great inconvenience of this method of evolution could be incorporated modifications caused by non- permanent environmental changes.

Certain structural changes, although small, can mean a step backwards if carried out using non-permanent environmental changes. The solution to this problem is again to use verification. However, the opposite case is also possible, that environmental changes are permanent. A global solution could be to permit the development of the improvements only if they are confirmed in two continuous generations. In order to achieve this, it would be necessary for one of the sexes not to incorporate modifications or, at least not from exogenous evolution.

In the above case, this limitation could be balanced with the transmission of a security copy and, at the same time, with specialisation in material technology to develop the new being efficiently from genetic information.

1.c) Internal cohesion or compatibility of the evolutionary system.  

To achieve similarity between individuals of the same species, it is necessary to carry out verification on certain modifications.

Any modification or improvement must be compatible with the rest of the information transmitted. In order to widen the field of possible improvements, it is possible to associate conditions of effective development from the modified character through the existence or non-existence of related characters. Thus, it is possible that a modification develops in a subsequent generation that is not necessarily the next one.

One aspect related with coherence is the necessity of evolutionary jumps - the birth of new species.

When a system evolves, it becomes complicated and at the same time certain characters form their structure, on which the behaviour of many other characters depends. With time, this structure becomes old and the time comes when it is necessary to change some elements of the structure to allow simplification of complicated processes and increase potential evolution.

As it is a new function, the verification condition will not be established; checks will have been made through simulation, or other control conditions will be established in case of error.

The consequent evolution will produce related characters and offspring of this new function (i.e., the necessity of a specific protein). If, due to the gene combination, a new being does not acquire this new function, the new being will not survive, as the dependent characters will be blocked.

As such, the distancing of the new species begins and this new species will be compatible with the original for a certain amount of time, but evolution will in time make it incompatible and will cause total separation.

The balance of the complementary characters is also related to coherence and could cause in some cases an evolutionary jump.

When two characters are perfectly complementary, balance is advisable, as the resulting potential will be greater. If two characters are from the above- mentioned nature, qualifying them and quantifying the global potential, means we will end up with the measurements shown in the following figure:

1.d) Optimisation of evolution.  

When genetic information is transmitted without needing another being, only one individual's experience is incorporated and only a new generation will mean the incorporation of another individual's experience - the evolution of one line is very slow.

If different experiences are joined, evolution will be much quicker and better. This implies genetic combination with other individuals and the possibility of verification of the information transmitted, in summary, sexual differentiation.

It seems clear that the older the individual, the greater the exogenous evolution, especially where modifications affecting functions experienced only during maturity are concerned.

Any repetition of an evolutionary step is a step backwards, a waste of time, energy and resources. This could be the reason why some species sacrifice the male after union, so that this evolutionary step is impossible.

There is no doubt that nature exists in a world where resources are scarce. Most of its time is spent surviving and survival of the offspring is not guaranteed; one solution could be to have as high a number of offspring as possible.

This very fact allows us to take advantage of the effect produced by the fight for survival: natural selection. In other words, different evolution lines could be attempted and natural selection will eliminate those who are less well adapted or weaker.

Another effect could be the need to make time to improve the species; in other words, specialisation in work will allow some individuals to dedicate their time to genetic perfection. This could be the case in the famous "drone" bees.
