The Myth of Beneficial Mutations
Mutation occurs at a rate of one for every ten million cell duplications. This is an insignificant number when compared to 100 trillion cells in a human body. Thus, the chance of having a couple of cells with a mutated form for every gene is possible without any noticeable effect.
Sickle Cell Anemia: The Poster Child for Beneficial Mutation
Sickle cell disease is one of a group of disorders that affects hemoglobin. This is the molecule in red blood cells that delivers oxygen to cells throughout the body. People with this particular hemoglobinopathy (autosomal recessive) have atypical hemoglobin molecules called hemoglobin S, which can distort red blood cells into a sickle, or crescent, shape that hematologist’s label drepanocytes.
Two Legacies that Changed the World
Both Darwin and Pasteur are two of the most well-known scientists of all time because they have had a profound impact in biological science leaving their imprint on the world. Charles Darwin provided us with his theory of evolution that, without question, rattled the fundamental foundations of the world’s need for a Creator.
