Thomas Lewis said “the capacity to blunder slightly is the real marvel of DNA. Without this special attribute, we would still be anaerobic bacteria and there would be no music” Explain what he means……

Solution

Blunder means a stupid or careless mistake. Mistakes are the very best to get anything useful done. The mistakes of DNA are the real driving force for evolution through mutation. By this simple creature becomes more complex. Mutations provide change. Different forms of life have been evolved. Continual variation in genetic material provides the bases of all evolved forms of life. Genetic variability, due to mutations in DNA, have many causes including errors during normal replication, insults from chemicals or radiation, jumps or transpositions of genetic materials, and other “spontaneous” changes. Our imperfection is God-given, built into our DNA, a gift of grace and cause for hope.DNA has the built in capacity for mistakes or imperfections. Today’s creation would not have happened. And we still remain today like the anaerobic bacteria with very little oxygen oxygen. Anaerobic bacteria do not live or grow when oxygen is present. The Great Oxygenation Event (GOE, also called the Oxygen Catastrophe, Oxygen Crisis, Oxygen Holocaust, Oxygen Revolution, or Great Oxidation) was the biologically induced appearance of dioxygen (O2) in Earth\'s atmosphere. The first autotrophy would have occurred without oxygen. After the appearance of oxygen-producing photosynthesis, oxygen so produced in water accumulated in the atmosphere and paved the way for to the arrival of aerobic organisms. The earliest evolution must have taken place in anaerobic conditions, i.e. in the absence of dioxygen. Oceanic cyanobacteria, which evolved into multicellular are believed to have become the first microbes to produce oxygen by photosynthesis. These evolutionary processes come out as the mutation or mistakes of DNA not by other means. Today’s life is the only cause of it.
