Question

As per the trends of evolution, which of the following happens?

• A. Complexity increases
• B. Evolution doesnot bring any change
• C. Complexity remains the same
• D. Evolution is not related to complexity

Answer 1

The correct option is A Complexity increases

In order to adapt and survive to the changing environment, organisms tend to evolve. As and when the organism evolves, their structural and functional aspects tend to increase in complexity to cope with the new conditions. For example, repeated exposure to pathogens tends to increase the complexity of the host immune response and aids in evading them efficiently.
