Answer 1

B. Assertion is correct but, the reason is wrong. (1 Mark)

Evolution is a slow and continuous process that takes a very long time to form new species. Mutation is the random change in an organism’s genetic makeup. Mutations result in variations but are not the only reason for it. It could also be due to other processes like genetic drift, gene flow and natural selection. (2 Marks)
