Detailed explanation-1: -Genetic mutation is the basis of species diversity among beetles, or any other organism. Mutations are changes in the genetic sequence, and they are a main cause of diversity among organisms. These changes occur at many different levels, and they can have widely differing consequences.
Detailed explanation-2: -The genetic diversity has three different sources: mutation, recombination and immigration of genes.
Detailed explanation-3: -The ultimate source of all genetic variation is mutation. Mutation is important as the first step of evolution because it creates a new DNA sequence for a particular gene, creating a new allele. Recombination also can create a new DNA sequence (a new allele) for a specific gene through intragenic recombination.
