(N/A) The statement highlights that evolution and natural selection are emergent phenomena resulting from fundamental biological mechanisms.
$1$. Living organisms exhibit a high tendency for rapid reproduction,which leads to an exponential increase in population size.
$2$. However,environmental resources such as food,space,and ecological niches are limited.
$3$. This creates intense interspecific and intraspecific competition for survival.
$4$. Within a population,individuals develop variations due to genetic mutations,gene flow,and genetic recombination during sexual reproduction.
$5$. This results in a heterogeneous population where individuals possess different traits.
$6$. Natural selection acts upon this existing heterogeneity,favoring individuals with advantageous traits that enhance their survival and reproductive success.
$7$. Over generations,the differential reproduction of these individuals leads to changes in allele frequencies,which is the essence of evolution.
Therefore,evolution and natural selection are not independent processes but are the cumulative outcomes of reproduction,competition,variation,and differential survival.
