NASA’s discovery of an arsenic-ingesting microbe in California’s forbidding Mono Lake looks, on the surface, like bad news for Darwinists hopeful to show what a no-big-deal it is for a planet to bring forth life unguided. The bacterium evidently uses arsenic for purposes that all other known organisms would use phosphorus, including incorporating it in DNA. A reporter for Nature News cites UC Santa Barbara geomicrobiologist David Valentine as observing that the discovery may mean “you can potentially cross phosphorus off the list of elements required for life.” That’s interesting. Under Darwinian assumptions, the observation that such an alternative life chemistry is possible means that some planets previously assumed to be inhospitable to life, due to being poor in phosphorus, Read More ›
