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.
D. Overproduction of offspring. Darwin's theory of natural selection states that species tend to overproduce due to limiting resources. This sets up competition or a struggle for existence. Those most fit in that environment are likely to survive, passing those favorable genes on to their offspring. In time, a new species evolves from the accumulation of favorable genes. Punctuated equilibrium is a theory that was formulated after Darwin's theory and it states that species remain relatively stable for long periods of time and then, due to some natural catastrophe, change rapidly in a short period of time.
