Evidence of Evolution

Front

What is artificial selection?

Back

Artificial selection is the process by which humans breed plants and animals for specific traits.

Front

What is a positive aspect of artificial selection?

Back

It ensures that human-preferred traits are available in animals and plants.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

How can environmental changes affect a species?

Back

Environmental changes can lead to extinction if a species cannot adapt to new conditions.

Front

What does it mean for a species to adapt?

Back

To adapt means to change in response to environmental pressures, allowing a species to survive and reproduce.

Front

What is a common ancestor?

Back

A common ancestor is a species from which two or more different species have evolved.

Front

What evidence supports the theory of evolution?

Back

Fossils, genetic similarities, and anatomical structures provide evidence for evolution.

Front

What is extinction?

Back

Extinction is the end of an organism or a group of organisms, often due to inability to adapt.

Front

What role do predators play in natural selection?

Back

Predators can influence the survival of prey species by selecting for traits that enhance survival.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a population.
