Evolutionary biochemistry has some serious problems: Chemical stability, chemical reactivity and chemical selectivity are noteworthy.
You can read the rest of "Evolution Hopes You Don't Know Chemistry: The Problem of Control", here.According to modern evolutionary theory, the recipe for life is a chance accumulation of carbon, hydrogen, nitrogen, and oxygen; add a pinch of phosphorus and sulfur, simmer for millions of years, and repeat if necessary. As a Ph.D. organic chemist, I am trained to understand the principles of chemistry, but this is not how chemicals react. Chemicals reacting with chemicals is a chemical reaction, and chemical reactions do not produce life. Life must create life. In the chemical literature, there is not a single example of life resulting from a chemical reaction. If life from chemicals were possible, it would be called spontaneous generation, an idea that scientists once thought happened in nature. Centuries ago, scientists used to believe that bread crumbs turned into mice because if you left bread crumbs on a table and returned later, the crumbs were gone and only mice were present. When true science got involved, they learned the truth that bread crumbs only attracted the mice that ate the crumbs. These scientists were quick to propose a theory that sounded reasonable until, that is, they studied the process and learned otherwise.Proteins and DNA are complicated chemical molecules that are present within our body. Cells which make up the living body contain DNA, the blueprint for all life, and proteins regulating biochemical processes, leading scientists to conclude these components are the cause of life. While it is true that all living bodies have proteins and DNA, so do dead bodies. These chemicals are necessary for life to exist, but they do not "create" life by their presence; they only "maintain" the life that is already present. However, this is not the only problem with the "life from chemicals" theory.
