Even taking the existence of Cytochrome C as a given, that evolutionary processes “predict” life’s pattern is a stretch.
Evolutionary theory is highly flexible. Evolutionists “adapt” evolution to try to fit any data.
If Cytochrome C sequences (beyond a limited number of shared amino acids required to form the protein) were totally random between species, then Evolutionists would ‘explain’ the random pattern as a result of ‘neutral mutation’. After all they believe that ‘random’ mutation is the source of genetic variation. (They would tell us that a creator would not have done it this way and that it is evidence of random naturalistic processes instead).
