@farmerman,
PS, when you engage Llewontin' critique of Carl Sagan' hortatory style to prove that "Science has delivered the goods", I get a kick out of it coming from a Creationist "no belief except my belief is valid"
Lewontin is, on th other hand exhorting against the "know it all" attitude of Sgan while still rcognizing that the only way e can moe foroward is by teps that hav us going backward several steps at various times. Noone in cience should discount that fact. Weve had a jolly discussion herein (o maybe anothr board) about Gould's and Lwontins
"Spandrels of San Marco" . Where He and Gould use this wholly impressive analogy to make a point about associated phenotypic changes that evolv along with essential ones. (basically some phenotypic evolved changes have a purpose and others, usually "riding along" while offering no reproductive advantage).
The funny thing was that THEN in the early 1990's, we had little idea about these "spandrels" .Today, with what weve been doing in uncovering other genetic facts, we have a much better idea. ( News lines are admonished to no longer announce that weve got a CURE for some kind of cancer, but we do say that something " THIS May be promising" based on prelim testing).
Spandrels hav come and gone as a breakthrough so, like most anything you Creationist dudes present, it appears that your possibly at least 25 years out of date(usually more) .
You guys still have a hard-on against natural selection eh?
