The process of evolution has been categorized into different mechanisms to explain a change in a studied species. The most well known mechanism is the theory of natural selection. This theory describes how evolutionary changes are dictated by the survival rate of reproducing specimens. For instance a dark haired artic rabbit would be easily spotted by predators and eaten thus ending their ability to procreate and pass along the dark haired gene. While the white rabbit in the same region would have a greater survival rate and would pass the white haired gene along to its descendants.
Genetic drift, much like the theory of natural selection, is based on the reproduction percentage of a certain trait within a particular species. Unlike natural selection, genetic drift theory is not based on adaptation due to need for survival; instead these changes are a function of chance. A group of insects pushed into an area of like insects with different traits by a chance wind could......
