Except for the minor detail that this isn't true. Nor is it true that Yockey's 1996 statement means what you think it means. Otherwise he would not have clarified his position in 2000, saying the opposite of what you are saying.
But for the record, I am going to attempt to get a response from Yockey regarding his position on abiogenesis. This will take some time, because I will have to go through a website that he corresponds with.
js1138, I was relying on a later source: Information Theory, Evolution, and the Origin of Life, which Yockey published in 2005 (Cambridge University Press, IIRC).
