The molecule cytochrome c supports the theory of evolution as biochemical evidence. Which of the following is not part of that evidence?
A) Cytochrome c has evolved multiple times among many species.
B) Cytochrome c has the same function in all organisms.
C) The genetic code for cytochrome c differs among species.
D) Cytochrome c is found in a variety of organisms from yeast to humans.
E) Cytochrome c plays a role critical to survival. Cytochrome c sequence comparisons show evolution in that this molecule has a common function important for cellular metabolism and it is present in many species but is variable among them. This pattern illustrates that cytochrome c evolved once in an ancestor and was passed to all of its descendents with modification through time unique to each species.
