Natural selection is when favorable traits are passed down to offspring while harmful and less favorable traits are eliminated, due to higher predation, competition from the o â¦ rganisms with more favored traits, etc. Since organisms with more favored traits will, logically, have much more chance of surviving to reproduce than those who lack the favored traits, the next generations will slowly start to accumulate a higher percentage of organisms who have the favored traits.
The natural genetic variation within a population of organisms means that some individuals will survive more successfully than others in their current environment.Factors which affect reproductive success are also important, an issue which Charles Darwin developed in his ideas on sexual selection.icroevolution is the change in allele frequencies that occur over time within a population.
