What importance does overproduction play in darwin's theory of evolution by natural selection
jarptica [38.1K]

<span>Overproduction means that a population reproduces many offsprings that their habitat or environment can sustain. This results to increased competition for resources in the population. Consequently, the aspect of ‘survival for the fittest’ applies as those individuals with superior traits will bear offspring that will preserve the traits while those with inferior traits will have reduced offsprings over time hence will wither out.  </span>
