<h3>What is evolution?</h3>Evolution is determined as changes in the population of a species. This implies over time one or more changes will occur in a population, these changes are usually a change in the frequency of a trait, in this case, the frequency of snails with/without bands.
<h3>How to identify the evolution?</h3>The population is evolving if the Hardy-Weinberg equilibrium is lost, this means the alleles are changing from one generation to the other.
