A process by which the better fit variants in a population become over-represented over time.
Natural selection is defined as
The process being described is known as natural selection. Natural selection is one of the key mechanisms of evolution and refers to the process by which organisms better adapted to their environment tend to survive and produce more offspring, passing on their advantageous traits to future generations.
Natural selection occurs when there is variation among individuals in a population for a particular trait, and this variation affects survival or reproduction. Those individuals with traits better suited for their environment will be more likely to survive and reproduce, passing on these advantageous traits to their offspring. Over time, this leads to a gradual increase in the frequency of these advantageous traits in the population, while the frequency of less advantageous or detrimental traits decreases.
The idea of natural selection was first proposed by Charles Darwin, who observed that organisms with traits that were better adapted to their environment were more likely to survive and pass on their traits to future generations. This process of natural selection provides a mechanism for species to adapt and evolve over time, as the frequency of beneficial traits increases and the frequency of less advantageous traits decreases.
