The sequential order here is genetic information >> natural selection >> evolution. This order allowed the emergence of new adaptations (e.g., the gecko's coloration).
<h3>Natural selection</h3>
Natural selection is the main mechanism by which evolution occurs.
Evolution means descendence with modifications, it is a process that depends on the differential survival and reproduction of the most adapted individuals in a given environment.
Genetic information (variation) is a prerequisite for evolution to occur.
