FAQs on Mindmap: Evolution - Biology Class 12 - NEET

1. What is evolution?
Evolution is the process by which different species of organisms have developed and diversified over time from a common ancestor. It involves changes in genetic traits within a population that are passed on from one generation to another.
2. How does evolution occur?
Evolution occurs through a process called natural selection. This means that individuals with traits that are better suited to their environment are more likely to survive and reproduce, passing on these advantageous traits to future generations. Over time, this leads to the adaptation and evolution of species.
3. What evidence supports the theory of evolution?
There is a wide range of evidence that supports the theory of evolution. Fossil records show a progression of species over time, with more primitive forms appearing in older layers of rock and more complex organisms in more recent layers. Comparative anatomy, embryology, and molecular biology also provide evidence for common ancestry among different species.
4. Can evolution occur within a single lifetime?
Evolution typically occurs over long periods of time and is not observable within a single lifetime. However, small-scale changes can be observed within a population over a shorter period through processes such as genetic mutations or changes in gene frequencies.
5. Does evolution conflict with religious beliefs?
The concept of evolution has been a topic of controversy when it comes to religious beliefs. While some religious interpretations may conflict with the idea of evolution, many religious denominations and individuals see no conflict between their faith and accepting the scientific evidence for evolution. They view evolution as a natural mechanism employed by a higher power.
