For those who wanted sources:
What Cofty said:
"The number of possible amino acid sequences that would result in a functional Cytochrome C protein molecule has been calculated to be a billion times larger than all the atoms in the known universe."
The source:
Yockey, H. P. (1992) Information Theory and Molecular Biology. New York, Cambridge University Press.
Given the information that Cofty has (which is very good, thank you for the amazing amount of research opportunities that this has given me), I think he got the info for the post from here:

This page goes into very great detail as to why this is an incredible confirmation of one important part of the modern evolutionary theory: common descent.
If there are 10^93 different aminoacid combinations that yield a functional cytochrome C, why then, can you make a relationship between the different species, just based on the tiny differences in this molecule?
The evidence clearly points to common descent.
