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.
The above is from page 16 of this thread.
The number of different possible functional versions of cyctochrome c sequences calculted by Yockey is staggering (2.3 x 10 93 ).
However, Yockeys calculations also show that when compared to the number of random possible sequences of the same length as cyctochrome c (110 amino acid length = 1.15 x 10 137 possible sequences) that functional cyctochrome c sequences are exceedingly rare.
The odds of obtaining even one of these by chance is 2.0 x 10 -44
Has any evolutionist demonstrated enough likely trials and time available on the Earth to likely obtain one functional cytochrome c sequence?
