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.

the actual answer was 160934

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
