Detailed explanation-1: -Overproduction of offspring’s leads to competition among individuals in which the fittest and adapted individual survives. Overproduction is also known as a driving force in natural selection as it can lead to adaptation and variation in a species.
Detailed explanation-2: -From Malthus, Darwin knew that populations could grow faste r than their resources. This “overproduction of offspring” led to a “struggle for existence, ‘’ in Darwin’s words. From artificial selection, Darwin knew that some offspring have variations that occur by chance, and that can be inherited.
Detailed explanation-3: -Intraspecific competition (negative density-dependence) lowers abundance, which decreases the supply rate of beneficial mutations, hindering evolutionary rescue. On the other hand, interspecific competition can aid evolutionary rescue when it speeds adaptation by increasing the strength of selection.
