In response to my point that “The calculations by Yockey were not just for optimum sequences but for all possible functional sequences.” Cofty replied:
No it wasn't. You can't even understand the creationist arguments AGAINST the science. How on earth are you going to understand the hard stuff?
Please provide a specific reference and quotation with context
On the bottom of page 16 of this thread and on the top of page 17 it was pointed out by another evolutionist here, and Cofty, that talkorigins was a source used. (Or that it was a source used by a source used).
The talkorigins article on “protein functional redundancy” cites Yockey’s 1992
“Importantly, Hubert Yockey has done a careful study in which he calculated that there are a minimum of 2.3 x 1093 possible functional cytochrome c protein sequences, based on these genetic mutational analyses (Hampsey et al. 1986; Hampsey et al. 1988; Yockey 1992, Ch. 6, p. 254). For perspective, the number 1093 is about one billion times larger than the number of atoms in the visible universe.”
Note the words “possible functional cytochrome c protein sequences”
