The inherited characteristics within a population change over time.

Explanation:

The evolution is related to the changes in the inherited characteristics over time in the biological population with the successive generation. These are inherited characteristics that are based on genes and passed from generation to generation through the process of offspring during reproduction.

Evolution can occur when the natural selection and the genes drift act together at the same level. The result is that some characteristics in the generation are common and some characteristics are different in this new generation.
