What is the geographic distribution of species?
Range. In biology, the range of a species is the geographical area within which that species can be found. Within that range, distribution is the general structure of the species population, while dispersion is the variation in its population density.
What is the importance of geographical distribution?
Distribution is an important part of economics, as well as geography. In the economic sense, distribution is the process where the producer of a good or service makes it available to consumers. A farmer may grow a crop, and then distribute it to stores or supermarkets. a geographic region.

Definition. The number of inhabitants in or spread across designated subdivisions of an area, region, city or country.
How do geographic barriers affect the evolution of species?
In allopatric speciation, organisms of an ancestral species evolve into two or more descendant species after a period of physical separation caused by a geographic barrier, such as a mountain range, rockslide, or river. Sometimes barriers, such as a lava flow, split populations by changing the landscape.
