Mutation

Detailed explanation-1: -Macroevolution is genetic change that occurs over long time scales, resulting in large changes in heritable traits in a population; changes large enough that we consider this population a unique taxonomic group, or species. Macroevolution is sometimes also termed speciation (the process by which a new species arises).
Detailed explanation-2: -An example of macroevolution is the evolution of a new species. One mechanism that drives evolution is natural selection, which is a process that increases the frequency of advantageous alleles in a population.
Detailed explanation-3: -The basic evolutionary mechanisms-mutation, migration, genetic drift, and natural selection-can produce major evolutionary change if given enough time.
Detailed explanation-4: -In other words, mutation, migration, genetic drift, and natural selection can produce major evolutionary changes given enough time.
