One of the most well-known human changes comes from Africa, where some humans' red blood cells changed to help the body combat malaria. When a person carries a copy of this genetic sequence, their red blood cells change shape when infected by malaria, helping the immune system identify them so it can destroy the cells and virus with it.

You might be familiar with the chronic condition which comes from having two copies of the sequence, however: sickle cell anemia.
