Importance of Evolution

As a biological fact, evolution represents a transcendental change for a species as a possibility for its survival in the face of changes. that they are capable of experimenting, as well as with respect to other species with which they share a niche, such as their own predators and even more so those that serve as a food source, in order to maintain symbiotic relationships, and with it the balance in the ecosystem.

Therefore, the evolution of the species marks a fundamental importance at the time of the preservation -of a necessary balance-, in the relationship between the living beings and the geographic and climatic phenomena of its ecosystem, becoming the most frequent and important external stimuli when to evaluate which are the main promoting factors in evolution, so this can help us to understand, even, how they have changed the conditions of the planet throughout the geological eras and how these changes have affected the various forms of life.

Evolution is a process of transformation in

characteristics physiological, anatomical and even social in living beings, as a response mechanism to the multiple factors provided by their environment. However, for a change to be considered a real evolutionary event, it must manifest itself as a process in a whole community of a same species, maintaining itself through several generations, and not only in one individual, since in the latter case, the change could simply disappear after his death and not have represented anything for the rest of the members of his species, becoming just a mutation particular.

Study

It is inevitable to mention Charles Darwin (1809-1882), recognized and consolidated over the years as the main builder of the theory of evolution, however, was not the only one in his own time to ask the right questions, and even more so, to ventured towards the search for the answers that allowed, since then, the development of evolution as a field of study scientist.

Since the contributions of Lamarck (1744-1829), prior to Darwin himself, the number of discoveries that have been made on this subject to this day has become innumerable. Even so, it is not possible to finish completing the immense puzzle of adaptations, changes and stimuli that produced them, in each one of them. the species that coexist with us, those that have long since disappeared, and not even the human species itself, leaving us the disturbing question for which no one has an answer yet: will we ever be able to solve all the mysteries hidden in the evolution? With each new evidence that is found, the evolutionary puzzle grows larger in missing pieces, so this is an area of ​​concern. investigation science that will continue to have a great future and importance in all its aspects.

Adaptation and changes in Evolution

Without the capacity for transformation, induced by the need to adapt to external changes, living beings defined as species would simply disappear with great ease in the face of any variation of the environment in which they are found, and that could represent a considerable alteration in the essential elements that a certain species requires for its survival.

This is how we can affirm that a species changes as its environment changes, and this close relationship of constant transformations leads to evolution. For example, birds. If we consider the fact of flying as a measure of evolution, given the need that this particular group of living beings has to be able to adapt to the constant changes experienced by their food sources, as soon as these begin to become scarce in their immediate environment, the birds, without their flight, simply they would starve to death, waiting for the tree they feed on to grow fruit again, or for the insect population to replenish, or for any other being that enters. on your menu.

The above example is limited to a single basic fact necessary for life: the feeding. Well, there are many other essential factors, such as reproduction, shelter and trophic relationships between species, which, without evolution, balances could not be established between the factors and the environment, and all this has to happen for each of the species alive.

The most essential importance of evolution has been -and will be- allowing the continuity of life on the planet, above any circumstance and however drastic it may be. The species that manages to adapt to adversity is the one that will undoubtedly prevail, despite the fact that this implies transformations. physiological, anatomical and behavioral such that, in the eyes of the scientific classification system of living beings, they are can consider species completely different from the ancestor that started the process of evolution so that its descendants they survived.
