• Evolution is the process of heritable change in populations of organisms over multiple generations.
  
• Selection is the preferential survival and reproduction or preferential elimination of individuals with certain genotypes (genetic compositions), by means of natural or artificial controlling factors.
• The specialization is the adaptation of an organism or organ to a special function or environment.
