Question

The process of descent with modification as a result of which present day species have risen from those of past is known as

• A. Variation
• B. Selection
• C. Evolution
• D. All of the above

Answer 1

The correct option is C Evolution

Evolution is change in heritable traits of biological populations over successive generations. Evolutionary processes give rise to diversity at every level of biological organisation, including the level of species, individual organisms, and at the level of molecular evolution. So, evolution is the process of descent with modification as a result of which present day species have risen from those of past.

Therefore, the correct answer is option C.
