Let's say a geographical barrier separates a species into two different population. Which also cause a reproductive isolation ( the two pupolations cannot interbred)
Throughout the time (lets say a million years), the two populations will undergo a lot of changes in their respective genomes and eventually will form 2 different species.
If there is no reproductive isolation, the 2 population could interbred with one another and there will be no speciation
