Question

what is allopatric speciation?
○ evolution of analogous structures not present in the last common ancestor of two species
○ prevention of gene flow between two populations due to physical or behavioral barriers
○ the reintroduction of geographically isolated species that leads to the production of viable hybrids
○ the divergence of two species from a common ancestor while in the same geographical location
○ two species diverging from a common ancestor due to geographical isolation

Explanation:

Allopatric speciation is a type of speciation that occurs when a population of organisms is geographically isolated from the rest of the species. Over time, the isolated population evolves independently due to different environmental pressures, leading to the formation of a new species. The key factor in allopatric speciation is geographical isolation, which prevents gene flow between the isolated population and the main population.

Answer:

two species diverging from a common ancestor due to geographical isolation
