explain the process of evolution through isolation that results in speciation.

Brief Explanations:

Isolation can be geographical (physical separation), ecological (different habitats), or behavioral (mating - behavior differences). When a population is isolated, gene flow between the isolated group and the main population stops. Mutations occur randomly in the isolated group. Natural selection acts on these mutations based on the new environment of the isolated group. Over time, genetic differences accumulate. Eventually, the isolated group becomes reproductively isolated from the original population, leading to speciation.

Answer:

Isolation stops gene - flow. Mutations occur and natural selection acts on them in the isolated group. Genetic differences accumulate over time, leading to reproductive isolation and speciation.
