Casey Luskin is The Wedge

There's a multimedia element to my post this time around. Well, an annotated YouTube video. Trust me, the stupid isn't nearly as compelling until you watch it.

Discovery Institute front-man Casey Luskin appeared on Fox News' rather conservative "Fox and Friends" show recently to warn us all that we're being hoodwinked by them mainstream science types. Biology textbooks, Luskin claims, neglect to incoproporate any scientific evidence which "contradicts Darwin". Apparently, the teaching of evolution in American schools (and perhaps elsewhere) is plagued with inaccuracies. This quite modest plague apparently consists of two items which, if you can believe it of a God-fearing institution, are total bullshit. Isn't it strange how the people raising this most important issue also happen to be peddling Intelligent Design, a crudely-disguised version of Creationism. The presenter correctly identifies that the teaching of evolution is a "white hot" issue. I guess the failure of the show to bring on someone from say, the other side of the debate, to speak on the show may have something to do with that "and Friends" bit of the show title.

First up in the non-torrent of non-issues is the apparent inclusion of the debunked "Haeckel's Embryos" illustrations in biology texts, which I have to admit I have never seen presented as factual. Of course, what Luskin does not mention is that the point that Haeckel's admittedly fabricated drawings of vertebrate embryos compared side-by-side has in fact been fully validated by genuine embryology work. This work has shown that we can find common combinations of morphological traits between the embryos of the vertebrate species. We gain an insight that we don't always get from comparing adult organisms. It is this modern and well researched take on Haeckel's work is what we typically find in biology texts. And it is that science which actually upsets Luskin and company who, it is repeated so many times as to be suspicious, do not want to teach your kids creationism. For definite. Okay?

Second, the ghost of a recent New Scientist article (which screamed Darwin Was Wrong from the front cover before going on to essentially admit that he... wasn't wrong) is summoned to frighten us. The article discussed the phenomenon of horizontal gene transfer (HGT), whereby genetic material can pass from one species to another without descent. HGT makes a mess out of the lineage of the bacteria because they make such transfers quite frequently. However, Casey Luskin would like us to believe that this has proven wrong the concept of the tree of life entirely. But HGT is quite remarkably rare amongst species bigger than the single-celled organisms that live in in the humid forests of Luskin's substantial eyebrows. The awkward truth that Luskin and other ID proponents need to explain is why when we arrange bigger, multicellular species by the combinations of common traits they posses, we get a tree shape. That's just how their traits are distributed, the tree is not a human fabrication and it is certainly not under threat. It's taught as a part of evolution because when it comes to the animals and plants we see around us, it's very much real and relevant.

Luskin's entirely unchallenged arguments are aired here, with some added annotations from yours truly.
