https://evolution.berkeley.edu/evolution-101/speciation/causes-of-speciation/

WEBScientists think that geographic isolation is a common way for the process of speciation to begin: rivers change course, mountains rise, continents drift, organisms migrate, and what was once a continuous population is divided into two or more smaller populations.

WEBGeographic isolation refers to the separation of members of a population by a physical barrier, such as a mountain or body of water, which disrupts the gene flow between them and begins the process of speciation.

WEBGeographic isolation occurs when two populations of the same species are divided by some type of geographic event or object. This event or object physically prevents two populations from being in the same area, preventing them from mating. As an example, let's look at a species of fish.

Allopatric speciation - Wikipedia
wikipedia.org

https://en.wikipedia.org/wiki/Allopatric_speciation

WEBIn allopatric speciation, a species population becomes separated by a geographic barrier, whereby reproductive isolation evolves producing two separate species. From this, if a recently separated population comes in contact again, low fitness hybrids may form, but reinforcement acts to complete the speciation process.

Geographical isolation may ultimately lead to the populations becoming separate species by adaptive radiation. See also allopatric; speciation.
