Natural Selection

What does the concept of Descent with Modification explain?

• It outlines the methods of modern genetic engineering.

• It describes the process of aging in humans.

• It explains how children inherit traits from their parents with slight changes.

• It discusses the principles of physics in natural processes.

How does selective breeding relate to natural selection?

• Selective breeding is an artificial form of natural selection where humans select traits.

• Both processes involve human intervention to select traits.

• Selective breeding is a natural process without human intervention.

• There is no relationship; they are completely different processes.

What role does nature play in natural selection?

• Nature passively allows all traits to be passed on.

• Nature selects traits that enhance survival and reproduction.

• Nature's role is limited to creating new traits only.

• Nature randomly chooses traits without any selection criteria.

What is the significance of Darwin's theory of natural selection?

• It disproved the theory of evolution.

• It provided a mechanism for how complex life forms evolved from simpler ones.

• It showed that natural selection does not occur in nature.

• It confirmed that all species on Earth come from a single species.
