How Evolution Works

One of the most popular theories in evolution 에볼루션 is Darwin’s theory of evolution. It states that over time, different forms of life have developed through changes in their DNA, and that these changes have led to the ability of some forms of organisms to survive and thrive better than other forms. This was a major revelation of evolution that has had a profound effect on how we think about the world around us today. And yet, many people argue against evolution, citing instances where transitional forms between organisms have been discovered, pointing out that such similarities could be due to random chance.


Darwin’s theory is actually nothing more than a method of science known as natural selection. Evolution is a gradual change over successive generations in the genetic makeup of a species. These changes are the outcome of genes being passed on from one parent to their offspring during reproduction. Over time, this will result in changes that make it possible for species to adapt to their environment, grow and develop in a particular way. These changes are commonly referred to as evolution, and there are a number of different theories that attempt to explain how this can happen.

One of the most well-known theories on evolution is the genealogical theory. This states that over the course of history, certain strains of a species of plant or animal have developed highly desirable traits that have allowed them to become the dominant species in their respective environments. Those that cannot tolerate these traits can often be exterminated through controlled breeding, and through the selective breeding of the superior type of traits. There is also a concept of positive evolution, which sees the evolution of a species as a beneficial trait that helped its ancestors survive in their environment. Sometimes this comes down to the simple fact that a particular trait was useful to the members of the environment, and that those members should keep it because it was useful to them.

There is also the theory of viral evolution, also known as viral natural selection. In this theory, an organism acquires different types of traits that are helpful for its survival in the environment, and it uses these traits to alter its DNA in order to change its appearance and function so that it can adapt to its new environment. The DNA that is altered is often passed down from one generation to another, and from one species of organism to another. It is also sometimes passed down by way of inheritance, meaning that a child of one person will usually carry the DNA that their parents carry.

Many of these theories regarding how evolution works have actually been disputed over the years, primarily by a group known as creationists. Creationists argue that the theory of evolution shows that all forms of life are equally evolved, and that they have evolved along with humans. There is also what is called the punctual evolution, wherein organisms actually evolve over time in a very small, incremental fashion. The creationists view this as proof that the Bible is the actual truth about evolution, and that all fossils actually show evidence of human evolution.

Charles Darwin was able to back up his theories about evolution in 1859, when he wrote ‘The Origin of Species’. It was then that he started writing ‘Theory of Selection’ and this is where he began to outline four mechanisms of evolution, namely, natural selection, drift, gene flow, and punctual evolution. In his book, he gave examples of physical differences between various species, such as the butterfly’s beautiful wings or the cat’s long tail. He also explained how there is natural selection, and how this works. He further explained through examples that adaptation can occur without any physical changes from a species being changed.
