FAQs on Micro & Macro Evolution Video Lecture - Biology Class 12 - NEET

1. What is the difference between micro and macro evolution?
Ans. Microevolution refers to small-scale genetic changes that occur within a population over a short period of time, such as the variation in beak size among finches on the Galapagos Islands. On the other hand, macroevolution refers to large-scale evolutionary changes that occur over long periods of time, resulting in the formation of new species or major evolutionary transitions.
2. How does microevolution contribute to macroevolution?
Ans. Microevolutionary changes, such as genetic mutations or natural selection acting on genetic variation, can accumulate over time and lead to the emergence of new species or major evolutionary transitions. These small-scale changes, when combined and accumulated, can result in significant macroevolutionary transformations.
3. Can microevolution be observed in real-time?
Ans. Yes, microevolution can be observed in real-time. Studies have shown examples of microevolutionary changes occurring within a few generations, such as the evolution of antibiotic resistance in bacteria or the development of pesticide resistance in insects. These observations provide evidence for the ongoing process of microevolution.
4. Is macroevolution a controversial concept?
Ans. While the scientific community widely accepts the concept of macroevolution, there are some individuals and groups who dispute it based on religious or ideological beliefs. However, the overwhelming majority of scientists agree that macroevolution is supported by extensive evidence from various fields of study, including paleontology, genetics, and comparative anatomy.
5. How does understanding micro and macro evolution contribute to our knowledge of biodiversity?
Ans. Understanding both micro and macro evolution is crucial for comprehending the patterns and processes that have shaped biodiversity on Earth. Microevolutionary changes within populations contribute to the genetic diversity that underlies species' ability to adapt and evolve. Macroevolutionary processes, on the other hand, have resulted in the vast array of species we see today, as well as their relationships and ecological roles within ecosystems. By studying these concepts, scientists can gain insights into the origins and maintenance of biodiversity, helping us to conserve and protect the natural world.
