What do genome maps allow scientists to determine?

Back

Genome maps allow scientists to determine how closely related different species are to each other.

Front

What is the likely outcome when an environment changes faster than a species can adapt?

Back

The most likely outcome is species extinction.

Front

What is artificial selection?

Back

Artificial selection is when humans decide which traits of an organism are the most desirable and only allow those organisms with those specific traits to breed.

Why do peppered moths tend to be the same color as the trees on which they live?

Back

Peppered moths tend to be the same color as the trees to make them harder to see from predators.

Front

What causes variations in species?

Back

Variations are caused by mutations.

Front

What is biological evolution?

Back

Biological evolution is the process through which species change over time through variations and natural selection.

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

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to variations in traits.

Front

What is the significance of adaptations in evolution?

Back

Adaptations are traits that enhance an organism's ability to survive and reproduce in its environment.

Front

What is the difference between artificial selection and natural selection?

Back

Artificial selection is driven by human choice, while natural selection is driven by environmental pressures.
