Question

1. Explain the concept of speciation. What conditions are necessary for one species to evolve into two separate species?





2. What is reproductive isolation, and why is it a crucial factor in the formation of new species?





3. Describe three ways in which reproductive isolation can occur, as outlined in the article. Provide examples for each type of isolation.





4. How did geographic isolation contribute to the speciation of Darwin's finches? Provide details on how this process led to the evolution of multiple finch species.





5. Give an example of behavioral isolation as a mechanism for reproductive isolation, as mentioned in the article. How does behavioral isolation prevent interbreeding between populations?





6. Why is it necessary for a population to become isolated from the original population for speciation to occur? Explain the role of isolation in the formation of new species.





7. Discuss the significance of genetic changes accumulating over time in the process of speciation. How do these genetic changes contribute to the development of distinct species?





8. Compare and contrast the three types of reproductive isolation (geographic, behavioral, temporal) in terms of how they prevent gene flow between populations. Provide examples to illustrate each type of reproductive isolation.
