The origin of species
In his first work, Darwin was already roughly implying some of his later contributions to science.
However, his theories and discoveries would not come to the public until 1859. Until now, Darwin had developed what would later be known as"Theory of Darwinian evolution."
In 1859, Darwin's most famous work (The Origin of Species through Natural Selection) was published. In this book he illustrated the theory by which he would finally be recognized.
His argument was in essence that all species of living beings, including humans, develop and adapt over time, being modified to adapt to new lifestyles and environments.
He no longer considered life as part of different ancestral lines, but as part of a single biological tree that branches out again and again.
In this way, it can be explained why all living beings share similar characteristics originating from the same ancestor. Darwin knew that if the reproduction of species occurred without supervision, and grew geometrically, the world would be overpopulated in future generations.
Darwin thought that if the world was not overpopulated it was because some species disappeared and others prevailed in time.
This theory was given the name of natural selection, indicating that the stronger species are more likely to survive, while the weaker species and less likely to adapt tend to disappear (Darwin, 1998).
3 - Theory of evolution
To begin with, there is an important difference between evolution and the proposed theories to explain the causes and mechanisms of it.
Evolution is defined as the genealogical connection existing between all living organisms, based on their descent from a common ancestor. This statement is based on the evidence.
First, there is the direct evidence of human observation and manipulation of species of domestic animals and plants for hundreds of years, with the aim of domesticating certain wild species and developing better crops, showing the existence of small gradual changes over time .
This can be seen clearly in the birds studied by Darwin in the Galapagos Islands, which had changes in the form of the peak due to general conditions of the environment, the availability of food and the presence of other animal species and of bacteria in the environment .
Biological changes occurring in species can be recorded and tracked in fossil findings. In this way, paleontologists have found multiple evidences and examples of sequential changes in the form of our ancestors in vast lines of time (Stark Effects, 2017).
Finally, the theory of evolution can be evidenced when common characteristics are found between different species, all coming from a common ancestor.
On some occasions, these similarities can only be explained as lags or vestiges that remained in the species. In this way, Darwin believed that humans have a number of physical characteristics that are only possible because they come from a common ancestor: fish.
Since Darwin's time, multiple mechanisms involved within the evolutionary process have been studied. In this way, you can see how they have had several mutations that have contributed to the process of natural selection taking place.
4- Natural Selection
Natural selection is the name given to the obvious process that indicates that some organisms are more likely to survive than others. This is due to a reproductive advantage that ensures the permanence of the species in future generations.
