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.
Mutations occurring in the reproductive cells, such as an egg or sperm, can be passed from one generation to the next. Most mutations have harmful effects, but some can increase an organism's ability to survive. A mutation that benefits a species may evolve by means of natural selection into a trait shared by all members.
