Multiple Choice

Why are mutations essential for evolution to occur in organic chemistry?

Mutations eliminate genetic variation, leading to a more uniform population.

Mutations introduce genetic diversity, which is necessary for natural selection.

Mutations prevent the formation of new species by maintaining genetic stability.

Mutations always result in harmful effects, which drive evolutionary change.

Verified step by step guidance

Understand that mutations are changes in the DNA sequence of an organism's genome. These changes can occur naturally or be induced by external factors.

Recognize that mutations are a source of genetic variation, which is crucial for the process of evolution. Without genetic variation, populations would not have the diversity needed for natural selection to act upon.

Consider that natural selection is a mechanism of evolution where individuals with advantageous traits are more likely to survive and reproduce. Mutations can introduce new traits that may be beneficial, neutral, or harmful.

Acknowledge that while some mutations can be harmful, others can be beneficial or have no effect at all. Beneficial mutations can lead to adaptations that improve an organism's chances of survival and reproduction.

Conclude that mutations are essential for evolution because they provide the raw material for natural selection to work on, leading to the development of new species and increased biodiversity over time.
