In a 1977 paper published in theJournal of Theoretical Biology, Hubert Yockey used information theory to evaluate the likelihood of the evolution of a relatively simple protein. Yockey’s model system was cytochrome c, a protein consisting of about one hundred amino acids. Cytochrome c plays an important role in the mitochondria’s electron transport chain (ETC) which helps to convert the chemical energy in carbon-carbon and carbon-hydrogen bonds, in the food we eat, to an electrochemical potential energy in the form of hydrogen ions (or protons) stored within the mitochondria’s inner membrane. Like water pressing against a dam and turning its turbines to generate electricity, the high-concentration hydrogen ions drive the ATP synthase “turbine” to create the high-energy ATP molecule. Like the electrical outlets in your house, the ATP molecule provides a standardized form of energy that is used for a wide range of applications in your body, such as muscle contraction and nerve signals. There is no scientific explanation for how the ETC evolved. There also is no scientific explanation for how a single protein, such as cytochrome c, evolved. Yockey explained this in 1977, and since then the problem has only gotten worse. Read more
