How do adaptations happen?
Beneficial mutations to DNA are picked by an organism to pass on to offspring
Beneficial mutations to DNA occur randomly and organisms pass them on to offspring
Beneficial mutations to DNA are caused by an organism choosing to adapt
Beneficial mutations to DNA are the only mutations that can be passed on to offspring
