WebApr 9, 2009 · Natural selection is a non-random difference in reproductive output among replicating entities, often due indirectly to differences in survival in a particular environment, leading to an increase in the proportion of beneficial, heritable characteristics within a population from one generation to the next. WebJan 15, 2024 · Natural selection works against all organisms, and it can be thought of as the environment and forces acting to stop organisms from surviving and reproducing. Therefore, organisms which are able to survive can also pass on their DNA to the next generation. This “selects” for those DNA sequences.
