BIOLOGY - Evolution - Mutations and Natural Selection

The video explains genetic mutations, which can be beneficial, neutral, or harmful. Mutations occur randomly and can affect an individual's ability to survive and reproduce. Natural selection helps incorporate beneficial mutations into a population while removing harmful ones. Sickle cell disease is highlighted as a harmful mutation, but it also provides immunity to malaria, demonstrating how mutations can have complex effects. Overall, mutations drive evolution through natural selection.

Explain how sickle cell disease is both a harmful mutation and a beneficial trait in relation to malaria.
