Human evolution is therefore one of the main ideas used for this concept, and in it both biological and natural components as well as cultural and social aspects merge.
When it comes to natural evolution, it refers to the development of microorganisms that, due to the need to acclimatize to various environmental conditions, obtained changes in their fundamental qualities.
These changes then made it easier for living beings to survive environmental changes. The impossibility of evolution symbolizes the extinction of millions of species of living beings.

Types of evolution
Biological evolution consists of a prolonged process of change of species through alterations generated in various generations, and that is evidenced in the modification of the allele frequencies of a population. Charles Darwin , is considered the father of the theory of evolution due to natural selection.
Usually it is known like evolution to any procedure of modification in the time. In the life sciences environment, evolution is an alteration in the genetic traits of a population of individuals, which can lead to the generation of new species, adaptation to different environments or the appearance of evolutionary innovations.
Human evolution is known as the procedure by which the human being becomes as it is today, after the evolutionary process. Contemporary man is part of the mammalian type and of the primate order .
The ancestors of today’s primates ate insects and lived in trees. Primates are divided into several categories, one of which is that of hominids.
The hominids about five million years ago, they left the trees, perhaps because they were disappearing, their feet altered until they were flat, which made it easier for them to walk, increased their brain and their intelligence developed.
Convergent evolution is called a phenomenon of evolution by which different beings, not so closely linked, tend to change with similar qualities, these can be ecological, morphological, physiological, among others.
Convergent evolution is presented by the need of the species to solve the same problem generated in two ecological niches in which each species survives and to which they need to adapt.
Nature gives convergent species the same solution for the problem they have in common, however, this occurs in each of the evolutionary categories.
Divergent evolution consists of the biological procedure that defines the deposit of differences between one or more species, with the aim of filling the habitats shared by different species.
Divergent evolution in turn gives way to another biological phenomenon known as speciation , in which beings from the same species diversify, producing different species, which still have qualities belonging to their ancestors, but each one has new characteristics, which They make it easy for them to fill new niches.
Evolutionary alterations that are generated at an equal or lower level than the species are known as microevolutionary changes. From the point of view of population genetics, microevolution is the modification in the allelic frequency of an appreciable population in a few generations.
Macroevolution consists of evolutionary modifications at large levels that break the species barrier, which can make room for new species and even harm higher taxonomic populations.
