Imagine a scenario in which a common population of animals is separated into two groups by a natural event. Over time, you might expect the two populations to become genetically similar. This process is known as speciation.

less genetically similar; Allopatric speciation

Explanation:

Allopatric speciation is a form of speciation in which a biological population of a species becomes isolated or divided by geographical features, thereby preventing gene flow between the divided subpopulations, which evolve differently into different new species. As a result of the forces of natural selection and genetic drift, the isolated subpopulations evolve into new species that are less genetically similar.

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
