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.
natural selection. The principle that only organisms best suited to their environment survive long enough to pass on their genetic characteristics to their offspring. According to this principle, the proportion of the species having these characteristics increases with each generation. Natural selection results from random variation of genetic traits in a species and forms the basis of the process of evolution. See Notes at adaptation, evolution.
