When comparing one organism to another, it can be difficult at times to identify similiarties. Our planet is home to billions of different organisms, each with unique charactersics. Within the infinitely large range of diversity, all organisms share one cominality; the backbone to all characteristic; DNA and gene expression;.
Within a specific species, there are thousands of possibilities for how a specific set of DNA will be expressed. Though there are 1000s of possible combinations, a species must have a method to be able to become better suited for the environment it’s implemented in. The act of favouring characteristics that favour survival is not an active thought, but one that occurs naturally within the subconcious (bennet). This act of favouring is better known in the whrelm of biology as natural selection. By definition, natural selection is the …show more content…
Many go unoticed, but when events such as natural disasters, geological change, illness or disruption by human beings occur, a species at the location of said event has the possibility of being effected. When a species is the victim to an unplanned disaster, the genetic diversity of their population can be effected from on generation to the next. (Reese). When said event occurs, the effect it has on genetic diversity is known as genetic drift.
While both genetic drift and natural selection will have an effect on a population, the rate at which they have effect varies. Genetic drift will effect the short term, due to the fact that it’s damage is exposed from one generation to the next because of a rapid decrease in population. Natural selection on the other hand will have long term effects on populations. The favouring of specific characteristics occurs over many generation. The change is so slow that it will go unnoticed from generation to the next, while the effects of genetic drift will be noticed within a few
