What is Evolutionary Biology? »Its Definition and Meaning [2019]

Evolutionary biology is the branch or discipline of biology that is responsible for studying the origin of species and their changes, dissemination, differentiation and any evolutionary process that arise in time, in a few words, studied since the beginning of the species, covering all the transformations suffered by this species over time, since it is responsible for the identification of each species with its ability to reproduce and compare the observed changes between each generation of the species studied.

To understand this context further, it is necessary to give a clear definition of the evolution ; Evolution is defined as the progressive or successive change that a population undergoes, this is influenced by the characteristics of the environment in which it lives, these changes are transmitted without being altered to subsequent generations that changes are made at the level of the genetic structure of individuals belonging to the species that suffer evolutionary variations.

In any environment, individuals of each species will reproduce and each individual must compete with those of the same species for their survival .Thus, according to the postulates of evolutionary biology, only the living beings that survive best survive They adapt to their environment.This is because each individual is different from others and only those whose characteristics are useful can survive.

This conception of life is based on the research of the British scientist Charles Darwin (1809-1882).n Darwin, the process that explains the changes in each species is known as natural selection.

The theory of the evolution of Darwin was exposed in his work «The Origin of the Species », A work that revolutionized biology, other branches of knowledge and worldview in general.Darwin explained the complexity and diversity of life as a whole.

The foundations of the selection Natural .Before Darwin's explanations, it was believed that the species had been created by the hand of God.His research contributed to a very different conception.

In conclusion, evolutionary biology was It focuses on competitive processes that cause genetic variation between populations through natural selection, natural selection is a theory proposed by Charles Darwin, this theory exposes or identifies the changes that are generated in a population to achieve adaptation to its environment, according to literature, evolution is the fundamental pillar for the study of biology, since it interconnects them and allows us to have a global concept of biological sciences.
