Speciation refers to a lineage-splitting event that is used to produce two or more separate species. The process takes place as a result of geographical isolation caused due to natural disasters and natural changes and also due to the reduction in gene flow. One of the main consequence of geographical isolation is speciation through reproductive isolation.
