Zombie Genes?
On August 19, Gina Kolata reported in The New York Times that geneticists “have seen a dead gene come back to life and cause a disease.” According to Kolata, the human genome “is riddled with dead genes, fossils of a sort, dating back hundreds of thousands of years–the genome’s equivalent of an attic full of broken and useless junk,” though some of those genes “can rise from the dead like zombies.” Now a supposed “zombie gene” is implicated in a type of muscular dystrophy abbreviated FSHD–a hereditary disease that affects about 1 in every 20,000 people. Kolata cites a recent Science article that begins by reviewing work dating back to the 1990s that establishes a link between FSHD and a Read More ›
Alfred Russel Wallace, Co-Discoverer of Evolution by Natural Selection — and “Creationist”
Despite repeated explanations that intelligent design is not creationism, Lauri Lebo at Religion Dispatches and others persist in equating the two. There’s a lot of bandying about of terms without defining them. One possible definition of “creationism” is the attempt to make scientific assertions regarding the natural world and/or the origin of life based upon a literal reading of Genesis. Yet with intelligent design, as David Klinghoffer points out, even if the source of the intelligence were identified as a deity, that wouldn’t make it creationism in this sense of Genesis literalism. In short, when it comes to speaking of “creationism,” there is a need for much greater clarity of thought and expression. I can think of no better illustration of Read More ›
