A.True
B.False

Answer 1

Evolution is a change/development in any organism on the basis of its features and characteristics. The changes can be due to genetic, physical and environmental factors.

Complete answer:
Different theories have been given by many biologists till date. Evolution is a slow process and it takes years to happen. The underlying causes of evolution are genetic drift, mutation, gene flow and natural selection.

According to Darwin's theory, evolution is caused by natural selection. It is a process in which organisms are favored by the environment. For example: giraffe’s necks grow over years from short to long in order to eat leaves from tall trees.
Whenever there’s a change in DNA sequence through cell division or any failure. Mutation is caused. Overall, evolution is an active process, it can never be stopped or paused. All living beings on earth are meant to be evolved. Though, the process of evolution can be different. Many modern methods have now been adapted which can trace the evolution. The recent example of evolution which can be taken in consideration is two different species of mice are mating and their hybrid mice pups are immune to pesticides.

Hence, the correct answer is option (B)

Note: Even a minor change in any species can lead to a whole new species causing evolution. And it is a continuous process which still keeps on taking place.
