Understanding Evolution in Biology

The subject of evolution 에볼루션 is one that sparks strong debate among many scientists and others who are uneducated in this area. Some evolutionists believe that all life on Earth began in one way, through a Creator. Others think that all life on Earth began in various ways, with many changes occurring along the way, some being permanent and others being temporary. Still, some evolutionists feel that all life on Earth began in a single way and that it will end in a single way, too. And, some creationists believe that there is a good explanation for all the facts that have been put forth regarding the origins of life on Earth.


How does evolution affect you? In broad terms, evolution affects all of us because it has the ability to shape our genetic makeup in different and unique ways. It is possible to alter your genetic makeup by natural selection, but this occurs very slowly over many generations and can be extremely expensive. When a person changes their entire genome, they are doing so not as a way to create new traits, but rather simply pass on their new “digital fingerprint” to future generations.

So, how are organisms different over time? Well, over millions of generations, each organism retains only a certain amount of information, which is passed down to their offspring. As organisms reproduce, those offspring will be changing, growing, mutating, and evolving in various ways. Species that are closely related tend to stay relatively identical within a large number of variations, while completely different species continue to change and evolve independently.

Is evolution accurate? Some people question the validity of evolution due to the fact that over millions of years, nothing is known about the past or what will happen in the future. To date, scientists can only study living organisms under the most stringent controls. Therefore, we are actually able to see very little about what was done in the past or will be done in the future. While there are several theories about the origin of life, none of them can be proven. There are several theories of evolution that do make sense, such as the genealogical theory, the punctual theory, and mutation theory, and random Walker’s theory, but none of these theories are completely accurate.

One example of how inconsistent the scientific method is with the concept of evolution is when an organism within a species undergoes natural selection and becomes extinct. Since the environment in which they originally lived did not provide their environment for thriving, the ancestor loses their ability to reproduce and become extinct. Now, what would have happened if their descendant had the ability to reproduce? Natural selection only allows for changes through the selective practice of crossing one species with another and the adaptation of specific traits, but there needs to be some kind of mechanism for the crossing and selection process to occur.

The difficulty in understanding biological evolution can be further explained by recognizing that each population has the goal of survival. For instance, a population of animals does not want to die off and become fossilized species. This is because each successive generation will attempt to reproduce and continue the line. As long as the goal of surviving is met then the theory of evolution will continue to hold sway in biology.
