Reason: Evolution is a fast , continuous and reversible process leading to increased complexity and adaptability.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) -Assertion is true but reason is false.
The assertion is correct, and the reason provided is incorrect.
Evolutionary biology is indeed the study of the history of life forms on Earth, tracing the changes in species over time. However, the reason stating that evolution is a fast, continuous, and reversible process leading to increased complexity and adaptability is inaccurate.
Evolution is a slow and continuous process that occurs over long periods of time, involving genetic changes in populations over generations. It is generally not considered fast or reversible, leading to increased complexity, adaptability and functional efficiency.
