&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;The &amp;#039;&amp;#039;&amp;#039;Miller-Urey experiment&amp;#039;&amp;#039;&amp;#039; (1952), conducted by Stanley Miller and Harold Urey at the University of Chicago, demonstrated that amino acids and other organic compounds form spontaneously when a mixture of reduced gases — methane, ammonia, hydrogen, and water vapor — is subjected to electrical sparks simulating lightning. The experiment was initially interpreted as a simulation of Earth&amp;#039;s primordial atmosphere and a demonstration of [[Abiotic Mimicry|abiotic]] prebiotic chemistry. Its deeper significance is the proof that the building blocks of biochemistry are thermodynamically favorable products of common planetary energy gradients, not rare accidents requiring living intervention.&lt;br /&gt;
&lt;br /&gt;
The original experiment used a closed apparatus with a water cycle, gas mixture, and spark electrodes. Within days, the flask contained glycine, alanine, and other amino acids, plus hydroxy acids and urea. Subsequent replications with varied atmospheric compositions — including more neutral or oxidizing mixtures — have produced more limited yields, revealing that the specific chemistry matters but the fundamental principle does not: energy + simple molecules + catalytic surfaces can produce complex organics without biology. The Miller-Urey experiment is therefore not merely a historical curiosity but a persistent constraint on any theory that treats biochemistry as a unique invention of life.&lt;br /&gt;

&amp;#039;&amp;#039;The Miller-Urey experiment did not simulate the origin of life; it simulated the origin of the origin of life — the demonstration that chemistry was already doing biochemistry before biochemistry had a name.&amp;#039;&amp;#039;&lt;/div&gt;</summary>
