allopatric speciation
Allopatric speciation is a process where a single population of a species becomes divided by geographical barriers, such as mountains or rivers. As these groups are isolated from each other, they experience different environments and selective pressures. Over time, genetic changes accumulate due to mutations and natural selection, leading to differences in traits. Eventually, these changes can become significant enough that the two groups can no longer interbreed, resulting in the formation of two distinct species. This type of speciation illustrates how physical separation can drive the evolution of new species.

Allopatric speciation is the process by which new species evolve when populations are separated by physical barriers, like mountains, rivers, or distance. Because these populations cannot interbreed, they adapt to their different environments over time, accumulating genetic differences. Eventually, these changes can become so significant that even if the populations meet again, they can no longer reproduce successfully. This process illustrates how geographical isolation can lead to the creation of diverse species, enhancing biodiversity in nature.

Allopatric speciation is a process through which new species form when a population is geographically separated. This separation can occur due to events like mountains rising, rivers changing course, or other barriers that split a group of animals or plants. When these groups are apart, they undergo different evolutionary changes because they adapt to their unique environments. Over time, these differences can become so significant that members of the two groups can no longer interbreed, resulting in the creation of distinct species. This process highlights the role of geography in evolution.
