Hint: It is the mechanism by which groups evolve and accumulate variations from the same common ancestor, resulting in the creation of new organisms. It can occur as a reaction to changes in abiotic factors, such as a change in environmental conditions, or when a new niche becomes open.

Complete answer:
The accumulation of variations between closely related populations within a species is divergent evolution or divergent selection, leading to speciation. Divergent evolution can be demonstrated by both orthologous genes (resulting from a speciation event) and paralogous genes (resulting from gene duplication).
In molecular evolution, the term can also be extended, such as to proteins that originate from homologous genes. Divergent evolution can be demonstrated by both orthologous genes (resulting from a speciation event) and paralogous genes (resulting from gene duplication). It is possible for divergent evolution to occur between two genes within a species through gene duplication. Similarities are due to their common origin among species that have diverged, so homologies are similarities. Conversely, after an adaptation has evolved independently, convergent evolution occurs, generating similar structures such as the wings of birds and insects.

Additional Information: In organisms of various phases or epochs in time, convergent evolution is the independent evolution of similar characteristics. Convergent evolution generates comparable structures that have identical shape or function but were not present in those groups' last common ancestor.
The independent evolution of related traits, beginning from a related ancestral state, is parallel evolution. This is also the case in more closely related lineages, where many species respond in a similar manner to similar challenges.
An atavism refers to a feature that is not present in an individual's immediate predecessors, although it existed in its ancestors. Due to the way genes act in the evolutionary process, this is likely.
So, the correct answer is ‘Divergent’.

Note: The creation of wings in bats from the same bones that shape the arm and hand or paw in the majority of other mammals is an example of divergence. Divergence is characterized as separating, converting, or having a difference of opinion into something different. When a teenager becomes an adult, an example of divergence.
