Explanation:
<u>
speciation by geographic isolation</u>
Spontaneous changes within the genome may arise during the process of cell division, called mutations. These are errors when copies of the DNA are made within the cell; mutations can range from small changes called single nucleotide polymorphisms to large-scale deletions and multi-gene additions.
These mutations form variants which, within a population, become stable, resulting in the formation of separate, genetically distinct populations called species. New species emerge through several volutionary mechanisms such as allopatric speciation -physical barriers to gene flow; separation of groups that develop independently in their environments by acquiring suitable characteristics
