The Origin of Life: Dangers of Taking Research Claims at Face Value | Evolution News

December 21, 2017

“…In an article here yesterday, I wrote about philosopher Vincent Torley’s critique of my posts related to the origin of life, and I corrected his errors on thermodynamics. Today, I will correct the errors related to the state of origins research. As a general overview, origin-of-life research falls into two categories. The first is experiments that attempt to accurately model the conditions on the early Earth. The classic example is the Stanley Miller experiment which started with a combination of reducing gases (methane, ammonia, and hydrogen) that were believed to exist, and the researchers applied to the mixture electrical discharges. The resulting reactions produced several amino acids, heralded as a major breakthrough.Unfortunately, scientists later recognized that the early atmosphere was not likely so reducing. Instead, it contained a different combination of gases including carbon dioxide. All subsequent experiments conducted with more realistic starting ingredients failed to produce the building blocks of life (amino acids, carbohydrates, nucleotides, and lipids) in significant quantities. An additional challenge for all such experiments, including Miller’s, was that they produced other byproducts that would have caused deleterious cross reactions. Such conditions would have prevented any subsequent stages leading to life. All roads led to dead ends…”
