first_imgHow can spiders drop straight down their dragline silk without going into dizzying spins on the way down?  It’s because spider silk has “shape memory” and a resistance to twisting, due to its unique molecular structure.  Scientists tested three strong threads for shape memory: Kevlar thread, copper thread, and spider silk.  The winner was spider silk; it also retained its flexibility after multiple twists.  The report in Nature1 was summarized by Bjorn Carey on LiveScience.1Emile et al., “Biopolymers: Shape memory in spider draglines,” Nature 440, 621 (30 March 2006) | doi:10.1038/440621a.Too bad the Darwinists are in power; they bring science to a halt claiming, “evolution did it.”  (This is called the Darwin-of-the-gaps fallacy.)  Think of how rock climbers and rescue workers could benefit from studying the lowly spider from a design perspective.  If we could just learn a little intelligent design from these lowly organisms, we would advance civilization and bring biology out of the Darkwin Ages.(Visited 30 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img
