Adaptive changes Vs. Random changes
Coyne states that "natural selection is the cause of all adaptive evolution." (143) It is certain that most people believe that natural selection is the driving force of evolution. However, other drivers such as genetic drift, can also change the course of evolution. According to the reading and any biological thoughts, in what situations would the force of natural selection prevail? What situations would give an advantage to genetic drift? If there was a specie that can survive perfectly in any, and all environments, would genetic drift help that being in anyway or is selectively and artificially preserving genetic code the way to be?
