View full document Name: How can changes in a population lead to new species Model 1 - Allopatric Speciation Geographic isolation is an isolating mechanism in nature. The process of splitting of genetically homogenous population into two or more populations that undergo genetic differentiation and eventual reproductive isolation is called speciation. For instance, the apple and hawthorne flies emerge at different times of year, and this genetically specified difference synchronizes them with the emergence date of the fruit on which they live.
