&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;A &amp;#039;&amp;#039;&amp;#039;biosignature&amp;#039;&amp;#039;&amp;#039; is any observable phenomenon that provides evidence of past or present life, as distinguished from abiotic processes that might mimic it. The concept is central to [[Astrobiology|astrobiology]] but its application is fraught with epistemic risk: every proposed biosignature has an abiotic false positive, and the history of the field is a history of premature claims. A robust biosignature must be coupled to a [[Planetary Context|planetary context]] that constrains the abiotic hypothesis space.&lt;br /&gt;
&lt;br /&gt;
The current best candidates — atmospheric disequilibrium, specific molecular chirality, and complex lipid distributions — are all probabilistic rather than definitive. The absence of a biosignature is not evidence of absence; the presence of one is evidence, not proof. The field urgently needs a theory of [[Abiotic Mimicry|abiotic mimicry]] that predicts which phenomena chemistry can fake and which it cannot.&lt;br /&gt;
