Resources evolution

In some parts of the world the need to exploit natural resources is so urgent that it has preceded the formulation of adequate environmental controls. The pace of natural resource exploitation and the growth of associated industries have overtaken the evolution of institutions, which would have the authority to exert such controls. 

Organisms also evolved powerful detoxifying mechanisms that remove toxic materials or convert them to non-toxic forms or nutrients. Examples of alterations to non-toxic forms are the conversions of hydrogen sulfide to sulfate and nitrite to nitrate. The prime example of development of the ability to use a toxic substance is the evolution of aerobic metabolism, which converted a serious and widespread toxin, oxygen, into a major resource. This development, as we have seen, greatly increased the productivity of the biosphere and generated the oxygen-rich atmosphere of today s Earth.

The quantification of adaptation is difficult because it is unlikely that any plant is in a state of perfect adaptation to its environment since it is made up of a collection of ancestral characteristics and the process of adaptation is occurring continually. Indeed, Harper (1982) has argued that we should refer to abaptation rather than adaptation - evolution from rather than evolution towards. We can say that adaptation to an environment depends on the possession of an optimum combination of characters that minimises deleterious effects and maximises advantageous effects (Bradshaw, 1965). We must bear in mind, however, that non-adaptive characters may evolve in parallel with adaptive characters by pleiotropy, and that the direction of adaptive change is limited by the available genetic resources of the species (Harper, 1982). This is part of the reason why Harper (1982) argues that...

When the resources in the environment are finite and individuals must compete for them, the situation is very different. Not only do the dynamics of population growth change completely because the population cannot expand indefinitely without bumping up against the limitations of the resources, but more interestingly for our purposes, the behavior of the population can then form the basis of a method for solving scientific problems. It is possible to use evolution as a problem-solving tool precisely because the characteristics of individual members of the population adjust in response... 

Over the years of evolution, Nature has developed enzymes which are able to catalyze a multitude of different transformations with amazing enhancements in rate [1]. Moreover, these enzyme proteins show a high specificity in most cases, allowing the enantioselective formation of chiral compounds. Therefore, it is not surprising that they have been used for decades as biocatalysts in the chemical synthesis in a flask. Besides their synthetic advantages, enzymes are also beneficial from an economical - and especially ecological - point of view, as they stand for renewable resources and biocompatible reaction conditions in most cases, which corresponds with the conception of Green Chemistry [2]. 

These are exciting times for molecular biology, now that the beginnings of a molecular account of development seem within reach. From this point of view, the role of research on DNA was similar to the role of the collection of facts of natural history in the formulation of the theory of evolution, an important stage but, ultimately, of little theoretical significance. The interesting structures and the interactions that make them possible all occur at the protein level. The cell co-opts for its use whatever resources it has available in its inherited DNA (and other units of inheritance). 

Increased information to the cells through internal sensors and transcription factors. Cells, therefore, became somewhat more aware of the changed environment and more able to respond to needs and risks presented by new resources for growth. This is a major theme of organisational improvement throughout evolution. 

Fig. 4.18 The denser the quants planned on the resources the more bottlenecks over time arise and the conflict numbers rise. An evolution is shown of three optimizations with permanent improvements. In the upper Gantt chart the conflicts are mostly in the middle time horizon of the Gantt chart. In the middle Gantt chart the conflicts are distributed over the whole time horizon.

Each valid evolution starts in a predefined initial state in which sufficient quantities of the raw materials are given. Furthermore, it must meet the requirements from Section 10.1.3. A schedule will be accepted only if the market demand has been satisfied. Hence, at the end of the evolution, the demanded quantities of final products must be present in the storages. Each evolution which does not satisfy the above requirements leads to an invalid schedule and thus must be rejected. In order to synthesize a valid and optimal schedule, the scheduler has to fix all degrees of freedom by choosing appropriate signals for the resource automata. A valid and optimal schedule corresponds to evolutions which minimize a given optimality criterion.
