larisa86 [58]

The survival rate is a measure of the fitness of each species. Option A is correct. Green beetles are more fit for the environment than brown beetles are.

<h3>What is fitness?</h3>

Fitness or Aptitude can be defined as the contribution of each genotype to the next generation.

Fitness is reflected by the phenotype that results in the survival, fertility, and capability of having a mate.

It is a way of measuring the individual ability to leave fertile offspring.

Aptitude must be significant to the natural selection act in its favor.

In the exposed example we can see the survival rate of two species.

The survival rate is telling us about the fitness of each species.

  • The green beetle increases its survival rate (fitness) each year

These results lead us to believe that the Green beetles are more fit for the environment than brown beetles are. Option A is correct.
