The mechanism in which organisms best suited for their environment survive
and reproduce <u>NATURAL SELECTION.</u>
<u></u>
Explanation:
When individuals in a population compete for resources or live in their environment, the individuals with the slightest advantage over the others have an increased chance of reaching maturity and reproducing to passing down their genes to the next generations.
Natural selection works on the variations of the population to ‘select’ the best alleles of genes in the population that offer an advantage in ‘survival for the fittest’. This how natural selection fits a population to its environment. The greater the variation within a population, the higher its capacity to adapt to changes in the environment.
