What is the role of mutations in evolution?

Back

Mutations are changes in DNA that can lead to new traits, which may be beneficial, harmful, or neutral, and contribute to evolution.

What is the difference between artificial selection and natural selection?

Back

Artificial selection is the intentional breeding of organisms for desired traits, while natural selection occurs without human intervention.
