lys-0071 [83]

The mechanism in which organisms best suited for their environment survive

<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.

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.
