The question of natural selection was replicated through the analogy for other areas, and by extension, the idea of Darwinism explained precisely these areas, where the strongest and capable is the one that survives while those that are not so adapted do not. When it comes to social processes, it is evident that Darwinism is a very cruel and aggressive situation.įor the natural selection process to occur, it is necessary that the differential biological effectiveness exists, that the phenotypic type is variable, and that this variation occurs through inheritance.Entropy measures the amount of decay or disorganization in a system as the system moves continually from order to chaos. Under this premise is that the evolutionary chain under which the idea of ? a missing link was interpreted, a variability that is missing to fully describe an evolution. However, this is not what happens: evolution is endowed with ramifications, with mixtures between species and modifications according to different adaptations to the environment, which is a correction that leaves out this idea of a missing link. The question of evolution implies an additional consideration because if the characteristics pass along the evolutionary process as explained, a linear sequence of species could be traced, getting to connect each of the genetic variabilities that were appearing. The non-poisonous king snakes, which mimic poisonous coral snakes.The orchids that are capable of deceiving wasps so that they ‘mate’ with them.The ability of human beings to learn to speak.The shape of the beak of the finches was modified over time because after the droughts they hardened allowing to eat harder seeds.The resistance to insecticides of some insects, which show the question of selection as a source of survival.The change of coloration of some moths, motivated by the industrial revolution in England. (Here the change in the environment was generated by man).The deformation of the jaw of the snake to swallow larger prey.The evolution of the human being in different species, called hominids.The cheetahs, which have survived the fastest.The case of the totality of the species that disappeared, and still continue to do so.The brown beetles have a greater chance of survival, and have more descendants, the population becoming frequent.The process of cloning, constantly developing but already proven in the facts, could potentially interfere with natural selection.The color change of a chameleon when it has prey, or to protect itself.The giraffes, of which the longest neck survived.The movements of the male blue-legged gannet, to attract its mate.The camouflage of grasshoppers, which makes them look like leaves.The white fur of the arctic animals, which allows them to hide in the snow.

The contribution of an individual to the next generation is recognized as biological efficacy, and it is a quantitative character that encompasses many others, related to the survival of the fittest and the differential reproduction of different genotypes. Natural selection is the central basis of all evolutionary change, being also the process through which the best-adapted organisms displace the less adapted by the slow and progressive accumulation of genetic changes.
