What is natural selection?

The mechanism by which organisms better adapted to their environment tend to survive and reproduce.

The process by which species randomly change over time.

A method of artificial breeding to create new species.

The random mutation of genes in organisms.

Which of the following provides evidence for evolution?

The steady population of species

What is a common misconception about evolution?

It only affects individual organisms and not populations.

It is a slow process that occurs over millions of years.

Natural selection plays a role in evolution.

Evolution leads to the development of new species.

What role do mutations play in evolution?

Mutations provide genetic variation, which can lead to adaptation.

Mutations always harm the organism.

Mutations do not affect evolution at all.

Mutations always result in the extinction of a species.

What is the significance of homologous structures in evolution?

They are structures that serve different purposes but share a common origin.

They are identical structures in different species.

They are structures that are always advantageous.

They are structures that have evolved independently in different species.

What is an example of artificial selection?

Breeding dogs for specific traits

The survival of giraffes with longer necks

The development of antibiotic-resistant bacteria

The formation of new islands from volcanic activity

What is genetic drift?

A gradual change in gene frequencies due to random events

A process of selective breeding

A form of evolution driven by natural selection

A process where organisms evolve identical traits

Which of the following best describes adaptation?

A trait that helps an organism survive and reproduce in its environment

A random change in an organism’s behavior

A sudden shift in a species' genetic makeup

An organism's ability to control its own evolution

What is the basic premise of the theory of evolution?

Life on Earth has remained unchanged since its creation.

Species evolve over time through natural selection and adaptation.

Species evolve randomly without any specific environmental factors.

Evolution is only applicable to plants, not animals.
