The molecule cytochrome c supports the theory of evolution as biochemical evidence. Which of the following is part of that evidence?
A) Cytochrome c has the same function in all organisms.
B) The genetic code for cytochrome c differs among species.
C) Cytochrome c is found in a variety of organisms from yeast to humans.
D) Cytochrome c plays a role critical to survival.
E) All of the above answers describe reasons why cytochrome c supports the theory of evolution.

Question

Quizplus · Accepted Answer

Cytochrome c is a molecule that supports the theory of evolution through biochemical evidence because it is conserved across different species (indicating a common ancestry), has the same critical survival function in various organisms, and its genetic code shows variations among species that can trace evolutionary relationships.
