Genetic mutations drive the variability of traits within a population from "summary" of The Red Queen by Matt Ridley
In the world of biology, genetic mutations play a crucial role in driving the variability of traits within a population. These mutations are random changes in the DNA sequence of an organism, which can lead to alterations in physical characteristics or behaviors. As these mutations accumulate over generations, they contribute to the diversity seen within a species. When a genetic mutation occurs, it can result in different phenotypic traits being expressed in individuals. Some mutations may be advantageous, providing a survival or reproductive advantage, while others may be detrimental. The variation created by these mutations allows for natural selection to act upon individuals with traits that are better suited to their environment. Through the process of natural selection, individuals with beneficial mutations are more likely to survive and reproduce, passing on their advantageous traits to future gen...
