The sequence begins with a mutation, which can introduce new genetic variations into a population. Over time, this can lead to variation within the population. Natural selection then acts upon this variation, favoring certain traits that enhance survival and reproduction. This can lead to reproductive isolation, as individuals with certain advantageous traits may mate preferentially with one another. Eventually, this can lead to the development of distinct species through the process of speciation.
