During which process do offspring from a common ancestor become increasingly different over time?

• A. Convergent evolution
• B. Divergent evolution
• C. Adaptive radiation
• D. Speciation

Answer: (B)

The process by which offspring from a common ancestor become increasingly different over time is known as divergent evolution. In this process, groups of organisms that share a common lineage evolve different traits and characteristics, often in response to different environmental pressures or ecological niches. This leads to the development of distinct species, each adapted to its specific environment. Divergent evolution explains why we see a variety of species emerging from a common ancestor, such as the various species of finches on the Galápagos Islands, each exhibiting different beak shapes suited for different food sources. This diversification is a key aspect of the evolutionary process, highlighting how species adapt over time, leading to an increase in diversity from a shared lineage. Other processes like convergent evolution, adaptive radiation, and speciation involve different mechanisms or contexts of evolution but do not specifically emphasize the gradual increase in differences from a common ancestor over time as clearly as divergent evolution does.
